EPSON Stylus Photo R200/R210 Revision A
1.1 Overview
This chapter describes how to identify troubles in two levels: unit level repair and
component level repair. Refer to the flowchart in this chapter to identify the defective
unit and perform component level repair if necessary. This ch apter also ex plains m otor
coil resistance, Sensor specification and error indication.

Since "CR Motor" and APG Motor are DC motors, the resistance among the electric
poles varies. Therefore, judge if it is normal or abnormal based on if there is operation
of the motor or not; the resistance values cannot be used to judge the abnormality.
However, it is difficult to judge accurately, if it is not clear, replace the motor.

1.2 Troubleshooting with LED/LCD Indications and Status Mo nit or 3 Message
This section describes the LED/LCD indication, the STM3 message and the error condition when the printer detects an error in each operation such as the power on, the paper
loading/feeding and the ink absorption operatio n. (As for the screen shot in STM3 message, it’s used screen shot of Stylus Photo R300/310 as a substitute for that of Stylus Photo
R200/210.)

This error is detected when replacing the Ink
Cartridge, if the new cartridge is defective.
This error is detected when the ink consumption
reaches about 90%.
(Note)
When the Ink Low Condition is detected, the
Maintenance LED will blink. The printer will
continue to keep this LED status even if a new
Ink Cartridge is installed in the Ink Cartridge

1.3 Unit Level Troubleshooting
You can identify the troubles by using the checklist in this section after confirming the
LED/LCD indication on the control panel or the error message displayed on STM3 of
the PC connected to the printer. As a result, you can save the whole repair time. When
finding any faulty parts, refer to Chapter 2 "ASSEMBLY/DISASSEMBLY" and
replace them. Following tables describe the error conditions (LED/LCD and STM3)
and their possible cause.

Phenomenon Detail
When turning on the power, the printer
does not operate at all.
When turning on the power, the
initialization is performed correctly.
However, a Communication Error is
displayed on ST M3 even transf erring the
printing job to the printer.

1. Check if "Power Supply Bo ard Cable" is connect ed to
the CN2 on "Main Boa r d" .
2. Check if "Power Supply Board Cable" is not da maged.
1. Check if the correct mod el name is written in EEPROM
on "Main Board".
1. Check if "USB Cable" is connected properly bet ween
the printer and the PC.
1. Check if the Stylus Photo R200/R210 Printer Driver is
used for the printer job.
The following is the example of how to use the tables.
Example) When "Carriage Unit" is out of the home position at the power on timing,
the Fatal Error may be caused by the failure of "CR Motor". Moreover,
there are 3 possible causes on "CR Motor" failure.
(Note)
When individual part that makes up "Roller EJ Assy.", "PF Motor" and "Ink System
Assy." is defective, replace the Printer Mechanism with a new one basically. However,
if an individual part needs to be replaced urgently, execute the necessary operation by
referring to Chapter 2 "ASSEMBLY/DISASSEMBLY".
Check Point Remedy
1. Connect "Power Supply Board cable" to the
CN2 on "Main Board".
2. Replace "Power Supply Board" with a new
one.
* If the problem still occurs, replace "Main
Board".
1. Write proper Market Setting in the Adjustment
Program.
1. Connect the printer and the PC with a "USB
Cable".
1. Install the Stylus Phot o R200/R210 Pri nter
Driver in the PC.
