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.

You can identify the troubles by using the checklist in this section aft er con fir min g 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.

W A R N I N G
Disconnect the power cable before disassembling or assembling
the printer.
If you need to work on the printer with power applied, strictly
follow the instructions in this manual.
Wear protective goggles to protect your eyes from ink. If ink gets
in your eye, flush the eye with fresh water and see a doctor
immediately.
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
To protect sensitive microprocessors and circuitry, use static
discharge equipment, such as anti-static wrist straps, when
accessing internal components.
Never touch the ink or wasted ink with bare hands. If ink comes
into contact with your skin, wash it off with soap and water
immediately. If you have a skin irritation, consult a physician.
When reassembling the waste ink pads and tray, always make
sure that the waste ink tube is fitted correctly in the specified
place. Fitting the ink tube in other than the specified position can
cause ink leakage.
C A U T I O N
When transporting the printer after installing the ink cartridge,
be sure to pack the printer for transportation without removing
the ink cartridge.
Use only recommended tools for disassembling, assembling or
adjusting the printer. (Refer to Table 2-1 "Tool List".)

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".
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.
Caution for disassembly/assembly of Printer Mechanism
1. "Printer Mechanism" with "Housing, Lower"
• Do not hold "Guide Plate, CR" ⇒ 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
Assy.", "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.
Management of the reference position for installation
[Reason]
Accurate installation for each component of "Printer 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]
• 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]
• Check if the slot of "Frame, Main" is correctly attached to the projection
of "Housing, Lower".
[Z-axis]
• 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".
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 assemb ling/disassembling the printer mechanism, and how to ensure the q uality of reassembled product 35
Page 36
Stylus Photo R300/R310 Revision A
How to install "ASF Assy.", "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.
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.".
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.

4.1 Overview
This section provides information to maintain the printer in its optimum condition .
4.1.1 Cleaning
This printer has no mechanical components which require regular cleaning except the
Print Head. Therefore, when returning the printer from the user, check the following
parts and perform appropriate cleaning if stain is noticeable.
C A U T I O N
Housing
Use a clean soft cloth moistened with water and wipe off any dirt. If the Housings
are stained with ink, use a cloth moistened with neutral detergent to wipe it off.
Inside the printer
Never use chemical solvents, such as thinner, benzine, and
acetone to clean the exterior parts of the printer like the housing.
These chemicals may deform the components of the printer or
deteriorate the quality of the printer.
Be careful not to damage any components when you clean inside
the printer.
Do not scratch the surface of the PF Roller. Use a soft brush to
wipe off dust. Use a soft cloth moistened with alcohol to remove
ink stain.
4.1.2 Service Maintenance
If print irregularity (missing dot, white line, etc.) has occurred or the printer indicates
"Maintenance Error", take the following actions to clear the error.
Head Cleaning
If dot missing or banding phenomenon has occurred, use the Head Cleaning
function and perform the Print Head cleaning operation.* This function can be
performed by operating the control panel, the print driver utility and the
Adjustment Program.
When performed by operating the Control Panel, first make sure that the printer is
in stand-by status. Then, select the cleaning mode by pressing the Maintenance
button on the Control Panel. The message, "Beginning head cleaning" will be
displayed on LED. By pressing the OK button, the printer will start the cleaning
sequence.
When selecting the manual cleaning by the printer driver utility, the most
appropriate cleaning mode will be selected.
The following explanation is the operation process of the printer head cleaning by
the Printer Driver Utility.
Refer to Chapter 3 "ADJUSTMENT" for the operation of the Adjustment
Program.
* This product has three modes for Manual Cleaning, and it automatically selects
the best cleaning mode in accordance with the various conditions and performs
the operation. Therefore, the consumption of the ink by the manual cleaning
will vary according to the selected mode for the condition.
Use a vacuum cleaner to remove any paper dust.
LD Roller
When the paper loading function does not operate because friction of the LD
Roller has gone down due to paper dust, remove the dust by using a soft bruch or
soft cloth moistened with alcohol.

1. Select EPSON Status Monitor 3 in the Printer Driver Utility. Then make sure that
the printer connected to Status Monitor 3 is on standby status. If it is on standby,
the following will be displayed.
Figure 4-1. Display for Status Monitor 3
2. Select Head Cleaning in the Printer Driver Utility and execute the printer Head
Cleaning. After the cleaning, choose "Nozzle Check" and print the Nozzle Check
Pattern. If repeating the Print Head cleaning operation without choosing "Nozzle
Check", CL1, the weakest cleaning, will be repeated.
Maintenance Request Error
Ink is used for operations such as Head Cleaning as well as printing. In that case,
the ink is drained into the Waste Ink Pad and its amount is counted in the Waste
Ink Counter set in the EEPROM on the control board. When the preset value is
reached (Waste Ink Counter = Waste Ink Pad Counter A = variable between 20000
and 46750), The Waste Ink Counter detects that the Waste Ink Pad has reached its
predetermined limit. The Maintenance Request Error will be displayed on Status
Monitor 3 as shown below.
Figure 4-3. Maintenance Request Error Display on Status Monitor 3
If this occurs, replace the Waste Ink Pad and reset the Waste Ink Counter set in the
EEPROM. Resetting of the Waste Ink Counter can be done only from the
Adjustment Program since this product does not have the reset function for the
Waste Ink Counter through the operation Panel Switch. Refer to Chapter 3
"ADJUSTMENT" for the reset procedure. During repair service, the Waste Ink
Counter must be checked according to the firmware version, the Main Board
checker program version and the Nozzle Check Pattern of the Nozzle Check
Pattern Print. Because another "Maintenance Request Error" could occur after
returning the repaired product to the user, if the Waste Ink Counter is close to its
limit, it is recommended that the Waste Ink Pad be replaced.
