Chapter 1 Theory of operation
ENWW
Formatter-control system
The formatter is responsible for the following procedures:
●
Controlling sleep mode
●
Receiving and processing print data from the various product interfaces
●
Monitoring control-panel functions and relaying product-status information (through the control
panel and the network or bidirectional interface)
●
Developing and coordinating data placement and timing with the DC controller PCA
●
Storing font information
●
Communicating with the host computer through the network or the bidirectional interface
The formatter receives a print job from the network or bidirectional interface and separates it into image
information and instructions that control the printing process. The DC controller PCA synchronizes the
image-formation system with the paper-input and -output systems, and then signals the formatter to
send the print-image data.
The formatter also provides the electrical interface and mounting locations for an additional DIMM.
Sleep mode
NOTE: In the System Setup menu, this item is termed Sleep Delay.
This feature conserves power after the product has been idle for an adjustable period of time. When the
product is in Sleep Delay, the control-panel backlight is turned off, but the product retains all settings,
downloaded fonts, and macros. The default setting is for Sleep Delay to be enabled, and the product
enters Sleep Delay after a 30-minute idle time.
The product exits Sleep Delay and enters the warm-up cycle when any of the following events occur:
●
A print job, valid data, or a PML or PJL command is received
●
A control-panel button is pressed
●
A cover is opened
●
A paper tray is opened
●
The engine-test switch is pressed
NOTE: Product error messages override the Sleep message. The product enters Sleep Delay at the
appropriate time, but the error message continues to appear.
Input/output
The product has two I/O interfaces:
ENWW
●
A USB 2.0 port for connecting directly to a computer
●
An internal 10/100Base-T network port.
Formatter-control system
5
CPU
The formatter incorporates a 540 MHz Coldfire processor.
Memory
The random access memory (RAM) on the formatter PCA contains the page, I/O buffers, and the font
storage area. It stores printing and font information received from the host system, and can also serve
to temporarily store a full page of print-image data before the data is sent to the print engine. Memory
capacity can be increased by adding a DIMM to the formatter. Note that adding memory might also
increase the print speed for complex graphics.
NOTE: If the product encounters a problem when managing available memory, a clearable warning
message appears on the control-panel display.
Firmware
The firmware is contained on NAND flash memory soldered on the formatter board. A remote firmware
upgrade process is available, which overwrites the firmware in the NAND flash.
Nonvolatile memory
The product uses nonvolatile memory (NVRAM) to store device and user configuration settings. The
contents of NVRAM are retained when the product is turned off or disconnected.
PJL overview
The printer job language (PJL) is an integral part of configuration, in addition to the standard printer
command language (PCL). With standard cabling, the product can use PJL to perform a variety of
functions such as these:
●
Two-way communication with the host computer through a network connection or a USB
connection. The product can inform the host about such things as the control-panel settings, and
the control-panel settings can be changed from the host.
●
Dynamic I/O switching. The product uses this switching to be configured with a host on each I/O.
The product can receive data from more than one I/O simultaneously, until the I/O buffer is full.
This can occur even when the product is offline.
●
Context-sensitive switching. The product can automatically recognize the personality (PS or PCL)
of each job and configure itself to serve that personality.
●
Isolation of print environment settings from one print job to the next. For example, if a print job is
sent to the product in landscape mode, the subsequent print jobs print in landscape mode only if
they are formatted for landscape printing.
PML
The printer management language (PML) allows remote configuration and status read-back through the
I/O ports.
Control panel
The formatter sends and receives product status and command data to and from the control-panel PCA.

Fuser temperature control
The fuser temperature control maintains the fuser heater at its targeted temperature.
The fuser main heater and sub heater control the temperature of the fuser sleeve.
The DC controller monitors the main thermistor and the sleeve thermistor. The DC controller controls
the FUSER MAIN HEATER CONTROL (FSRD1) and the FUSER SUB-HEATER CONTROL (FSRD2)
signals according to the detected temperature. The fuser-heater control circuit controls the fuser heater
depending on the signal so that the heater remains at the targeted temperature.

Fuser protective function
The protective function detects an abnormal temperature rise of the fuser unit and interrupts power
supply to the fuser heater.
The following three protective components prevent an abnormal temperature rise of the fuser heater:
●
DC controller
◦
●
Fuser-heater safety circuit
◦
●
The fuser heater safety circuit interrupts power supply to the fuser heater when the detected
temperature of the main and sub thermistors is abnormal.
Thermal fuse
◦

The DC controller interrupts power supply to the fuser heater when it detects an abnormal
temperature of the fuser heater.
The thermal fuse is broken to interrupt power supply to the fuser heater when the thermoswitch
detects an abnormal temperature of the fuser heater.
Chapter 1 Theory of operation
ENWW
Fuser failure detection
The DC controller determines a fuser unit failure, deactivates the FUSER HEATER CONTROL signal,
releases the relay to interrupt power supply to the fuser heater and notifies the formatter of a failure
state when it encounters the following conditions:
ENWW
●
Abnormal temperature rise: The sleeve thermistor does not rise at a specified temperature within
a specified period after the fuser heater control starts.
●
Abnormally low temperature: The thermistors are at a specified temperature or lower during a print
operation or other fuser heating cycle.
●
Abnormally high temperature: The thermistors are at a specified temperature or higher, regardless
of the fuser control status.
●
Drive circuit abnormality: The frequency in the zerocross circuit is out of a specified range when
the product is turned on or is in the standby period.

Overcurrent/overvoltage protection
The low-voltage power supply has a protective circuit against overcurrent and overvoltage to prevent
failures in the power supply circuit. The low-voltage power supply automatically stops supplying the DC
voltage whenever excessive current flows or voltage abnormally increases.
If the dc voltage is not being supplied from the low-voltage power supply, the protective function may
be running. In this case, turn off the power switch and unplug the power cord. Do not turn the power
switch on until the root cause is found.
The LVPS has two fuses on the PCA. The LVPS 24V output is interrupted to the fuser and the highvoltage power supply if the either of the interlock switches (SW3 and SW4) is in the off position (door
open).
WARNING! The product power switch only interrupts dc voltage from the LVPS. The AC voltage is
present in the product when the power cord is plugged into a power receptacle and the power switch is
in the off position. You must unplug the product power cord before servicing the product.
WARNING! If you believe the overcurrent or overvoltage protection circuits have been activated, do
not plug in the product power cord or turn on the product power until the cause of the failure is found
and corrected.
In addition, fuses in the low-voltage power supply protect against overcurrent. If overcurrent flows into
the AC line, the fuses melt and cut off the power distribution.

Latent-image formation block
During the latent-image formation stage, the laser scanner forms invisible images on the photosensitive
drums in the print cartridges.
Pre-exposure
Step 1: Light from the pre-exposure LED strikes the photosensitive drum surface. This eliminates the
residual electrical charges on the drum surface.
Figure 1-14 Pre-exposure

Photosensitive drum
Primary charging
Step 2: DC and AC biases are applied to the primary charging roller, which transfers a uniform negative
potential to the photosensitive drum.

Laser beam exposure
Step 3: The laser beam scans the photosensitive drum to neutralize negative charges on parts of the
drum surface. An electrostatic latent image is formed on the drum where negative charges were
neutralized.

Developing block
Step 4: In the print cartridge, toner acquires a negative charge from the friction that occurs when the
developing roller rotates against the developing blade. The developing bias is applied to the developing
roller to create a difference in the electric potential of the drum. When the negatively charged toner
comes in contact with the photosensitive drum, it adheres to the latent image because the drum surface
has a higher potential.

Step 5: The toner on the photosensitive drum is transferred to the intermediate transfer belt (ITB). The
ITB is given a positive charge by the bias of the primary transfer roller. The negatively charged toner on
the drum surface is transferred onto the ITB. All four color planes are transferred onto the ITB in this
step.

Step 6: The toner image on the ITB is transferred to the paper. The secondary transfer bias is applied
to the secondary transfer roller to charge the paper positive. As the paper passes between the secondary
transfer roller and the ITB, the complete toner image on the ITB is transferred onto the paper.

Step 7: The elasticity of the paper and the curvature of the secondary transfer opposed roller cause the
paper to separate from the ITB. The static charge eliminator reduces back side static charge of the paper
and controls excess discharge after the transfer process for stable media feed and image quality.

Memory tag
The memory tag is a non-volatile memory chip in the cartridge that stores information about usage for
the cartridge. The product reads and writes the data in the memory tag. The DC controller determines
a memory tag error and notifies the formatter when it fails to either read from or write to the memory
tag.
Cartridge presence detection
The DC controller detects the presence of the cartridges by monitoring the RD sensor. When the DC
controller determines a cartridge absence, it notifies the formatter.
Toner level detection
The DC controller detects the remaining toner level in a cartridge by the optical detection method. The
DC controller notifies the formatter of the remaining toner level.
Cartridge life detection
The DC controller detects the cartridge life by monitoring the total operational wear limit or remaining
toner level of the cartridge. The DC controller determines a cartridge end of life and notifies the formatter
when the operational wear limit of the cartridge reaches a specified amount or the cartridge runs out of
toner.
Developing unit engagement and disengagement control
The developing unit engagement and disengagement control engages the developing unit with the
photosensitive drum or disengages the developing unit from the drum depending on the print mode: fullcolor mode or black-only mode. The developing unit is engaged only when required, preventing a
deterioration of the drums and maximizing their life.
The developing disengagement motor rotates the developing disengagement cam. As the cam rotates,
the developing unit engages with or separates from the photosensitive drum.
When the product is turned on and when each print job is completed, all four of the developing units
disengage from the photosensitive drums. When the print mode is in full-color mode, all of the developing
units engage with the drums. When the print mode is in black-only mode, only black developing unit
engages with the drum.

Chapter 1 Theory of operation
ENWW
The primary transfer roller engagement and disengagement control engages the ITB with the
photosensitive drum or disengages the ITB from the drum depending on the requirements of the print
job. There are three states of the primary transfer rollers.
●
All rollers disengaged: The ITB disengages from all the four photosensitive drums. This is the
state during a standby period, and it is the home position for the primary transfer rollers.
●
All rollers engaged: The ITB engages with all the four photosensitive drums. This is the state for
full-color jobs.
●
Only black roller engaged: The ITB engages with only the black photosensitive drum. This is the
state for the black-only jobs.
The operational sequence of the primary transfer roller engagement and disengagement control is as
follows:
1.
The fuser motor drives the primary transfer disengagement solenoid to rotate the primary transfer
disengagement cam.
2.
As the cam rotates, the YMC slide plate or the Bk slide plate moves to right or left. This causes the
primary transfer roller to move up or down.
3.
The ITB engages with or disengages from the photosensitive drum depending on the movement
of the primary transfer rollers.
The DC controller determines an abnormal primary transfer roller disengagement mechanism and
notifies the formatter when it does not detect a specified signal from the primary transfer disengagement
switch even though the primary transfer disengagement solenoid is driven.
ITB unit presence detection
The DC controller detects the ITB unit presence by monitoring the primary transfer disengagement
switch. The DC controller drives the primary transfer disengagement solenoid for specified times during
the initial rotation period of the following:
●
The product is turned on
●
The product exits Sleep mode
●
The door is closed
The DC controller determines an ITB unit absence and notifies the formatter when it does not detect a
specified signal from the primary transfer disengagement switch.
ITB cleaning mechanism
The cleaning blade in the ITB cleaner scrapes the residual toner off the ITB surface. The ITB motor
drives the residual toner feed screw and the screw deposits the residual toner in the toner collection
unit.
The DC controller detects whether the toner collection unit is full by monitoring the ITB residual toner
full sensor. When the DC controller determines the toner collection unit is full, it notifies the formatter.

The DC controller also detects the presence of the toner collection unit by monitoring the toner collection
unit switch.

Calibration
The product calibrates itself to print a high-quality image. The calibration corrects a color-misregistration
and color-density variation caused by environment changes or variation inherent in the product. The
product performs the following calibrations:
●
Color-misregistration control
●
Environment change control
●
Image stabilization control
Color-misregistration control
The color-misregistration control corrects the misaligned color caused by the variation inherent in the
laser scanner units or cartridges. The color-misregistration control corrects the following:
40
●
Horizontal scanning start position
●
Horizontal scanning magnification
●
Vertical scanning start position
Chapter 1 Theory of operation
ENWW
The DC controller forms pattern of toner on the surface of the ITB and measures a misaligned length
with the RD sensor and the RDL sensor. Accordingly, the formatter calibrates the color-misregistration.
Figure 1-29 Color-misregistration control
RD sensor
ITB

Pattern of toner
The DC controller commands the formatter to perform the color-misregistration control whenever one
of the following occurs:
●
The product is turned on or the door is closed, after replacing any one of the cartridges
●
The product is turned on or the door is closed, after replacing the ITB unit or the laser scanner unit
●
A specified number of pages have been printed
●
Continuous printing for a specified period of time
●
Cold starting of the fuser when the product is turned on
If data from the RD or RDL sensor is out of a specified range during the cartridge-presence detection
or when starting the color-misregistration control, the DC controller determines an abnormal sensor and
notifies the formatter.
Environment change control
The environment change control calibrates each high-voltage bias to obtain an appropriate image
according to the environment changes. The DC controller determines the environment, where the
product is installed, based on the surrounding temperature and humidity data from the environment
sensor. It adjusts the high-voltage biases to accommodate environmental changes.
The DC controller determines an environment sensor abnormality and notifies the formatter when it
detects out of specified range data from the environment sensor.
Image stabilization control
The image stabilization control reduces the fluctuations in image density caused by environmental
changes or deterioration of the photosensitive drums or toner. The two kinds of image stabilization
controls are image density control (DMAX) and image halftone control (DHALF).
ENWW
Image-formation system
41
Image density control (DMAX)
The image density control calibrates each high-voltage bias to stabilize the image density variation
caused by the deterioration of the photosensitive drum or toner. The DC controller commands the
formatter to control the image density under the following conditions:
●
The detected temperature of the fuser is a specified degree or lower when the product is turned
on
●
The product is turned on or the door is closed and also whenever a specified number is printed
after replacing any one of the cartridges
●
The product is turned on or the door is closed after replacing the ITB unit or the laser scanner unit
●
A specified number of pages have been printed
●
After a specified period of time from the previous image density control
●
The environment is changed for a specified condition after the previous image density control
Image halftone control (DHALF)
The image halftone control is performed by the formatter to calibrate the halftone. The DC controller
measures the halftone pattern according to a command from the formatter. Accordingly, the formatter
calibrates the halftone. The DC controller controls the image halftone under the following conditions:
42
●
The image density control is completed
●
The formatter sends a command

Pickup and feed block
The pickup-and-feed block picks one sheet of paper from the cassette or the MP tray and feeds it into
the fuser.
Cassette pickup
The operational sequence of the cassette pickup is as follows:
ENWW
1.
The product is turned on or the cassette is inserted.
2.
The lift-up operation and the lifting plate spring move up the lifting plate to the position where the
paper can be picked up.
3.
The DC controller rotates the pickup motor when it receives a print command from the formatter.

4.
The cassette (CST) feed roller rotates.
5.
The cassette (CST) pickup solenoid is driven at a specified timing.
6.
The cassette (CST) pickup roller rotates and picks up the paper.
7.
The cassette (CST) separation roller removes any multiple-fed sheets.
8.
One sheet of paper is fed into the product.
NOTE: The lift-up operation pushes up the lifting plate to keep the stack surface of paper at the pickup
position.

Cassette multiple-feed prevention
The product uses a separation roller method to prevent multiple sheets of print media from entering the
paper path. The cassette separation roller does not have its own driving force. Therefore the cassette
separation roller follows the rotation of the cassette pickup roller.
During normal feed, when the product picks up one piece of paper, the cassette separation roller is
driven by the cassette pickup roller through one sheet of paper. Thus the separation roller rotates in the
paper feed direction.
During multiple-feed, when the product picks up more than one piece of paper, the low friction force
between the sheets weakens the driving force from the cassette pickup roller. In addition, some braking
46
Chapter 1 Theory of operation
ENWW
force is always applied to the cassette separation roller, so the weak rotational force of the pickup roller
is not enough to rotate the separation roller. Therefore, the separation roller holds back any multiplefed sheets, and one sheet of paper is fed into the product.

Tray 1 (MP tray) paper pickup
The operational sequence of the MP tray pickup is as follows:
ENWW
1.
The DC controller rotates the pickup motor when it receives a print command from the formatter.
2.
As the MP tray pickup solenoid is driven, the MP tray pickup roller rotates and the lifting plate moves
up.
3.
The MP tray pickup roller picks up the paper.
4.
The MP tray separation pad removes any multiple-fed sheets and one sheet of paper is fed into
the product.

Tray 1 (MP tray) last-paper detection
The product detects whether the print media on the MP tray is the last sheet during continuous printing
to prevent toner contamination on the photosensitive drums and the ITB.
The product attempts to form the next image before the DC controller detects a media absence because
the paper path between the MP tray media-presence sensor and the registration roller is short. To
prevent the photosensitive drums and the ITB from being contaminated with toner, the last-paper sensor
detects the last-paper. The MP tray last-paper detection roller rotates when the last-paper is picked up.
48
Chapter 1 Theory of operation
ENWW
The DC controller notifies the formatter of a media absence when it detects the last-paper by the lastpaper sensor.

Paper feed
After the paper pickup operation, the paper picked up from either the cassette or MP tray is then fed to
the fixing-and-delivery block.
ENWW
1.
The registration shutter corrects the skew-feeding of the paper that is picked up from the cassette
or MP tray.
2.
When the TOP sensor detects the leading edge of paper, the DC controller controls the rotational
speed of the pickup motor to align with the leading edge of toner image on the ITB.
3.
The toner image on the ITB is transferred onto the paper, and the paper is fed to the fusing-and
delivery block.
Pickup, feed, and delivery system
49
The DC controller notifies the formatter of a paper size mismatch error when the paper length detected
by the TOP sensor does not match the paper size specified by the formatter.

Skew-feed prevention
The printer corrects the skew feed without decreasing the throughput.
1.
The leading edge of paper strikes the registration shutter and aligns.
2.
As the feed rollers keep pushing the paper, the paper gets warped against the registration shutter.
3.
The stiffness of paper pushes up the registration shutter and the realigned paper passes through

Fusing and delivery block
The fusing-and-delivery block fuses the toner image onto the print media and delivers the printed page
to the output bin.
Loop control
The product controls the loop (slackness) of print media to prevent the defects of print quality and media
feed.
52
●
If the fuser sleeve rotates slower than the ITB, the paper loop increases and an image defect or
paper crease occurs.
●
If the fuser sleeve rotates faster than the ITB, the paper loop decreases and an image is stretched
because the toner image is not transferred to the paper correctly
Chapter 1 Theory of operation
ENWW
Two loop sensors located between the fuser sleeve and the ITB detect the paper loop. Accordingly the
DC controller controls the rotational speed of the fuser motor to keep the loop amount properly.
●

●
Loop sensor 2: Detects the paper loop for plain media other than heavy media

Pressure roller pressurization and depressurization control
The product releases the pressure roller from the fuser sleeve, except during printing, to prevent
deforming the fuser sleeve and the pressure roller and to facilitate the jam-clearing procedure.
1.
The DC controller reverses the fuser motor to rotate the fixing pressure release cam.
2.
The pressure roller is pressurized or depressurized depending on the position of the cam.
The DC controller determines a fuser pressure-release mechanism abnormality and notifies the
formatter when it does not sense the fuser pressure-release sensor for a specified period from when it
reverses the fuser motor.

Introduction
This chapter describes the removal and replacement of field-replaceable units (FRUs) only.
Replacing FRUs is generally the reverse of removal. Occasionally, notes and tips are included to provide
directions for difficult or critical replacement procedures.
HP does not support repairing individual subassemblies or troubleshooting to the component level.
Note the length, diameter, color, type, and location of each screw. Be sure to return each screw to its
original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can become
damaged or broken. Frayed or pinched harness wires can be difficult to find. When replacing wire
harnesses, always use the provided wire loops, lance points, or wire-harness guides and retainers.

Use HP ToolboxFX to troubleshoot print-quality problems
NOTE: Before proceeding, print a Supplies status page to see the approximate number of pages
remaining for each print cartridge. See Reports menu on page 211.
From the HP ToolboxFX software you can print a page that helps identify whether a specific print
cartridge is causing the problem, or if the problem is with the product itself. The print-quality
troubleshooting page prints five bands of color, which are divided into four overlapping sections. By
examining each section, you can isolate the problem to a particular cartridge.
Section

This page helps identify four general issues:
●
Streaks in only one color: This is most likely a cartridge issue. Remove the cartridge and look
for debris on it. If no debris is found and the defect continues after the cartridge is reinstalled,
replace the cartridge.
●
Streaks in all colors (in same location): Clean the printer. See Solve image-quality problems
on page 240.
●
Repeating defect in multiple colors:
Repeating dot in multiple colors: If the dot repeats at roughly 76 or 79 mm, run a cleaning page to
clean the fuser, and run several white pages of paper to clean the roller. If defect does not repeat
at 76 or 79 mm, replace the cartridge of the color of the dot.

so they hold the stack firmly in place without bending it.
The media is binding or sticking together.
Remove the media, flex it, rotate it 180 degrees, or flip it over.
Reload the media into the input tray.
NOTE: Do not fan paper. Fanning can create static
electricity, which can cause paper to stick together.
The media is removed before it settles into the output bin.
Wait until the page completely settles in the output bin before
removing it.

How to use the parts lists and diagrams
The figures in this chapter show the major subassemblies in the product and their component parts. A
parts list table follows each exploded view assembly diagram. Each table lists the item number, the
associated part number, and the description of each part. If a part is not listed in the table, then it is not
a field replacement unit (FRU).
CAUTION: Be sure to order the correct part. When looking for part numbers for electrical components,
pay careful attention to the voltage that is listed in the description column. Doing so will ensure that the
part number selected is for the correct all-in-one model.
NOTE: In this manual, the abbreviation “PCA” stands for “printed circuit-board assembly.”
Components described as a PCA might consist of a single circuit board or a circuit board plus other
parts, such as cables and sensors.

Customer self-repair warranty service
HP products are designed with many Customer Self Repair (CSR) parts to minimize repair time and
allow for greater flexibility in performing defective parts replacement. If during the diagnosis period, HP
identifies that the repair can be accomplished by the use of a CSR part, HP will ship that part directly to
you for replacement. There are two categories of CSR parts: 1) Parts for which customer self repair is
mandatory. If you request HP to replace these parts, you will be charged for the travel and labor costs
of this service. 2) Parts for which customer self repair is optional. These parts are also designed for
Customer Self Repair. If, however, you require that HP replace them for you, this may be done at no
additional charge under the type of warranty service designated for your product.
Based on availability and where geography permits, CSR parts will be shipped for next business day
delivery. Same-day or four-hour delivery may be offered at an additional charge where geography
permits. If assistance is required, you can call the HP Technical Support Center and a technician will
help you over the phone. HP specifies in the materials shipped with a replacement CSR part whether
a defective part must be returned to HP. In cases where it is required to return the defective part to HP,
you must ship the defective part back to HP within a defined period of time, normally five (5) business
days. The defective part must be returned with the associated documentation in the provided shipping
material. Failure to return the defective part may result in HP billing you for the replacement. With a
customer self repair, HP will pay all shipping and part return costs and determine the courier/carrier to
be used.

Safety statements
Laser safety
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration has
implemented regulations for laser products manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. The device is certified as a “Class 1” laser product
under the U.S. Department of Health and Human Services (DHHS) Radiation Performance Standard
according to the Radiation Control for Health and Safety Act of 1968. Since radiation emitted inside the
device is completely confined within protective housings and external covers, the laser beam cannot
escape during any phase of normal user operation.
WARNING! Using controls, making adjustments, or performing procedures other than those specified
in this user guide may result in exposure to hazardous radiation.
