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.

1.3 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.

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

2.2 Caution regarding assembling/disassembling
the printer mechanism, and how to ensure the
quality of reassembled product

For the existing Low End models, it is basically forbidden to remove "Housing,
Lower" from "Printer Mechanism". This is because the strength of "Frame, Main" is
not strong enough, therefore, "Frame, Main" may be transformed when removing/
reinstalling it from/to "Housing, Lower".
For that reason, when replacing "Ink System" or "PF Motor", it is recommended to
replace not only "Housing, Lower" but also "Printer Mechanism".

For this printer, it is necessary that "Housing, Lower" be removed from "Printer
Mechanism" when replacing "Waste ink Pads" or "Ink System Unit".
Therefore, this chapter specifies the disassembly/assembly of "Printer Mechanism"
which "Housing, Lower" has been taken out in order to secure the quality of the
repaired items.

o Caution for disassembly/assembly of Printer Mechanism

1. "Printer Mechanism" with "Housing, Lower"

• Do not hold "Guide Plate, CR" Þ Transforming of "Frame, Main" and
"Guide Plate, CR" may give some bad influence to PG or printing.

• Do not touch "CR Guide Shaft" and/or the surface of the head nozzle.

2. "Printer Mechanism" without "Housing, Lower"

• Manage the standard values for installation. (See below)

• First, remove "Support Plate, Frame, Main". Then, remove "Roller PF
Unit", "Roller EJ Assy." and "Paper Guide, Front".

• Make sure to manage "Waste Ink Tube".

• Be careful with the interconnection of "Star Wheel/CDR Sensor"
connector cable.

• Assemble "Cam, CR, Left" while gearing with the APG gear.

n Management of the reference position for installation

[Reason]
Accurate installation for each comp onent of "Prin ter Mechanism" is on a basis
of "Housing, Lower".

[Support for Service]
Check if there is no gap between "Frame, Main" and "Housing, Lower".

[Reference]
In order to ensure the accuracy for installation, it is necessary to manage the
reference position for installation in X, Y and Z direction.

[X-axis direction]

• Check if "Frame, Main" is correctly set to the groove of "Housing,
Lower".

• Check if there is no gap between "Frame, Main" and "Housing, Lower".

[Y-axis direction]

• Check if the slot of "Frame, Main" is correctly attached to the projection
of "Housing, Lower".

[Z-axis direction]

• Check if there is no gap between "Frame, Main" and "Housing, Lower".

• Check if correctly secured with the hooks (2 on the left, 1 on the right, 1
on the right front) of "Printer Mechanism".

n Management of the perpendicular accuracy of "Guide Plate, CR" (The

standards of the guide rail's perpendicular direction is on the basis of the
hooks of "Carriage Unit" and "Print Head".)

[Reason]
Deformation of "Guide Plate, CR" may cause the defective print/operation.

[Support for Service]
Specify the correct raising position for "Main Frame" so that it will not be
deformed.

DISASSEMBLY AND ASSEMBLY Caution regarding assembling/disassembling the printer mechanism, and how to ensure the quality of reassembled product 34

EPSON Stylus Photo R200/R210 Revision A

n How to install "ASF Unit", "Main Board" and "Paper Guide, Upper"

[Reason]
When installing these three components, too much force can be given to
"Frame, Main", therefore, it may be deformed and cause the defective print/
operation.

[Support for Service]
Hold the opposite side of the components securely, when installing them.

3. CDR Guide Assy.

n Management of the level accuracy of "CDR Guide Assy."

[Reason]
Deformation of "CDR Guide Assy." may cause the defective print.

[Support for Service]
Disassemble/assemble carefully "CDR Guide Assy.".

o How to secure the quality for reassembled products

It can be judged that the quality for the reassembled products is guaranteed if the
printing test with the Adjustment program is successful.
