2.1 Overview

This chapter describes the operating principles of the printer mechanism and electric
circuit boards of Stylus Photo R280/R285/R290 and Epson Artisan 50/Epson Stylus
Photo T50/T59/T60/P50.

2.1.1 Printer Mechanism

The main components of the printer mechanism are shown in the table below.

Table 2-1. Printer Mechanism Main Components

Component Function

CR Unit

APG Unit

PF Unit Rotates the PF roller shaft to feed paper being powered by the PF motor.

ASF Unit

EJ Unit

Ink System

The main control boards are shown in the table below.

Main Board

Power Supply Board
(P/S ASSY)

Panel Board Located inside the Panel Unit and controls the operation panel.

Chapter 2 Operating Principles 2.1 Overview 23

Moves along the CR shaft to print on paper being powered by the CR motor.

The unit includes Printhead, PW sensor, and CR encoder sensor.

Moves the carriage upward/downward to adjust the platen gap being powered by
the PF motor. There are 4 preset levels of platen gap and the unit moves the
carriage to one of the levels according to the current carriage position detected by
the APG sensor.

Being powered by the PF motor, feeds paper loaded on the ASF into the printer
mechanism.

Being powered by the PF motor, ejects paper or the CDR tray.

The EJ frame moves corresponding to the stacker position so that the frame
matches with the paper size.

Located on the right side of the printer mechanism. Covers the printhead with the
cap holder when the printhead is not used, and draws waste ink out of the
printhead. The waste ink is sent to the Waste Ink Tray through the waste ink tube.

Table 2-2. Main Control Boards

Board Function

Located on top of the printer mechanism and controls all over the
printer operations.

Located on the Lower Housing and generates required voltages for the
printer using the power supplied from the AC power line.

2.2 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP)

 Overview

In order to ensure high print quality and high print speed, this product incorporates the Banding Reduction System (BRS) and Paper Feed Profile (PFP) Correction system. The
overview of them is described in the table below.

Summary

Conventional models perform overlapping printing (2-path or 4­path print) to reduce banding problem. Printers that incorporate the
Banding Reducing System do not perform the overlapping printing.
They carry out 1-path printing correcting ink drop amount for each
raster mode in order to avoid making a gap between each path
(printed line). This enables to achieve both high print quality (less
banding) and high print speed.

In the conventional method to improve paper feed accuracy, the
adjustment value is calculated based on a value obtained at a
certain point of paper. Therefore, correcting the total paper feed
amount (from when paper is fed and to when finishing printing)
was impossible. The Paper Feed Amount Profile Correction offers
more precise control over the paper feeding. Paper feed errors are
measured at various points and a correction value is calculated for
each of the points. This enables to ensure print quality in the target
print mode.

 Adjustment/Correction method

Correction values of the BRS and the PFP are automatically calculated when a pattern printed by the printer is scanned by a specified scanner. The created correction
values are stored into the serial flash ROM on the main board, and applied when printing in the target print mode.

For information on how to carry out the BRS and PFP,
See Chapter 5 Adjustment.
