Chapter 2 Operating Principles 2.1 Overview 22
2.1 Overview
This chapter describes the operating principles of the printer mechanism and electric
circuit boards of Stylus Photo R280/R285/R290.
2.1.1 Printer Mechanism
The main components of the printer mechanism are shown in the table below.
The main control boards are shown in the table below.
Figure 2-1. Printer Mechanism Diagram
Table 2-1. Printer Mechanism Main Components
Component Function
CR Unit
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.
APG Unit
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.
PF Unit Rotates the PF roller shaft to feed paper being powered by the PF motor.
ASF Unit
Being powered by the PF motor, feeds paper loaded on the ASF into the printer
mechanism.
EJ Unit
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.
Ink System
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.

Chapter 2 Operating Principles 2.2 Electrical Circuit Operating Principles 24
2.2 Electrical Circuit Operating Principles
The electric circuits of the Stylus Photo R280/R285/R290 consist of the following
boards.
2.2.1 Main Features
The circuits support multi-common printing method that achieves high-speed printing
reducing the number of carriage movements.
! Features of C691Main Board
An EEPROM and a reset circuit are mounted individually to reduce the cost.
This is achieved by removing a complex RTC circuit that is mounted on the
previous model (R260/R265/R270/R360/R380/R390). Stylus Photo R280/
R285/R290 do not need the complex RTC circuit because a backup timer is
not required for them.
! Operations to reduce power consumption
The printer carries out the following operations to go into sleep mode.
Decreases the power voltage.
Shuts off photoelectric current of photo interrupter sensors.
Stops the motor drive circuit.
Stops some part of the clock in the ASIC.
De-energizes the motors.
Makes the head drive circuit go into standby state.

Chapter 2 Operating Principles 2.3 Banding Reduction System (BRS) / Paper Feed Amount Profile Correction (PFP) 26
2.3 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.
! 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.

BRS
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.

PFP
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.

3.1 Overview
This chapter provides how to troubleshoot problems analyzing the cause based on the
messages shown by the printer driver, printer’s LED status and the observed symptom.
Identify and troubleshoot the problem referring to the tables on the following pages.
When some parts need to be replaced, make sure to follow the procedure given in
Chapter 4 and carry out required adjustments. If any abnormality is observed in motors
or sensors, check the electrical value referring to the 3.1.1 “ Troubleshooting on Motors
and Sensors”(p.28).
Figure 3-1. Troubleshooting Flowchart
3.1.1 Troubleshooting on Motors and Sensors
The following tables show the normal electric values of each motor and sensor. When
any abnormality is observed in motors and sensors, check their electric values and
compare them with the values given in the tables to see if the motors or sensors are
broken or not.
Note : See 2.1.2 “Motors & Sensors”(p.23) for locations of the motors and sensors.

3.2 Warning / Error Indications
This section describes how the printer indicates an error/warning status with LEDs, or
on the screen of the printer driver when a problem arises during various operations;
power-on sequence, paper feeding, ink drawing, printing, and so on.
3.2.1 Error Indication Method
The Stylus Photo R280/R285/R290 are equipped with LEDs. You can check most of
the troubles with the status of the LEDs or messages shown on the windows of
“EPSON Status Monitor 3”. (See 1.5.3 “Operation Buttons & LEDs Functions ”(p.18))
