Safety Precautions
All safety procedures described here shall be strictly adhered to by all parties servicing and maintaining this
product.
DANGER
Strictly observe the following cautions. Failure to comply could result in serious bodily injury or loss of life.
1. Always disconnect the product from the power source and peripheral devices when servicing the product or
performing maintenance.
2. When performing works described in this manual, do not connect to a power source until instructed to do so.
Connecting to a power source causes high voltage in the power supply unit and some electronic components
even if the product power switch is off. If you need to perform the work with the power cable connected to a
power source, use extreme caution to avoid electrical shock.
WARNING
Strictly observe the following cautions. Failure to comply may lead to personal injury or loss of life.
1. Always wear protective goggles for disassembly and reassembly to protect your eyes from ink in working. If
any ink gets in your eyes, wash your eyes with clean water and consult a doctor immediately.
2. When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use
of such products containing flammable gas is prohibited.
PRECAUTIONS
Strictly observe the following cautions. Failure to comply may lead to personal injury or damage of the product.
1. Repairs on Epson product should be performed only by an Epson certified repair technician.
2. No work should be performed on this product by persons unfamiliar with basic safety knowledge required for
electrician.
3. The power rating of this product is indicated on the serial number/rating plate. Never connect this product to
the power source whose voltages is different from the rated voltage.
4. Replace malfunctioning components only with those components provided or approved by Epson;
introduction of second-source ICs or other non-approved components may damage the product and void any
applicable Epson warranty.
5. The capacitors on the Main Board may be electrically charged right after the power turns off or after driving
motors which generates counter electromotive force such as when rotating the PF Roller or when moving the
CR Unit. There is a risk to damage the Main Board if the Head FFC is short-circuited with the capacitors on
the Main Board electrically charged, therefore, after the power turns off or after motors are driven, leave the
printer untouched for approximately 30 seconds to discharge the capacitors before starting disassembly/
reassembly.
6. To prevent the circuit boards from short-circuiting, be careful about the following when handling FFC or
cables.
When handling FFC, take care not to let the terminal section of FFC touch metal parts.
When connecting cables/FFC to the connectors on circuit boards, connect them straight to the connectors to avoid
slant insertion.
Confidential
7. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static
wrist straps, when accessing internal components.
8. Do not tilt this product immediately after initial ink charge, especially after performing the ink charge several
times. Doing so may cause ink to leak from the product because it may take some time for the waste ink pads
to completely absorb ink wasted due to the ink charge.
9. 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 doctor immediately.
10. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts

movement and
position*2
3-3.After the PE Sensor checks if paper exists, the PF Motor rotates clockwise for one second and releases the CR lock.
3-4.While checking if the CR Unit does not touch the Change Lever (CR lock) or the foreign material, the CR Unit
moves to the 80-digit side slowly until it touches the Left Frame.
3-5.The distance from the position where the CR Unit touched to the Left Frame is regarded as the standard distance
from the origin position, and the home position is fixed.
From then on, the CR Unit position is monitored according to the signals from the CR Encoder.
3-6.The CR Unit moves to near its home position quickly.

Condition 2: Power-on sequence after recovering from a paper jam error (See Table 1-2.)
Turning on the printer after turning it off with a paper jam fatal error.
There still remains paper on the paper path out of the detecting area of the PE Sensor.
Maintenance error recovery has never been performed.

Operation
CR Unit/PF Roller
movement and
position
4-3.The CR Unit quickly returns to its home position, and displays on the LCD or with flashing LEDs that the paper jam
error occurs.
When the user removes the paper and releases the paper jam error by panel operation, the normal power-on sequence from No.1 (Table 1-1) is executed
again.*2
Note *1: Paper exists is detected when the CR Unit touches the paper. When paper does not exist is detected, the power-on sequence
of condition 1 (Table 1-1) is executed from No.4.
*2: If the paper jam error cannot be solved after repeating the power-on sequence on condition 2 (Table 1-2) twice, the printer turns
into the paper jam fatal error for the third time.
To recover from the maintenance error, the dedicated software that can be downloaded
from the web site which can be accessed from STM3 is required.
The printer operation related to the maintenance error recovery is as follows.
When the waste ink counter reaches the threshold value (1) for the first time and the
maintenance error occurs, the counter threshold of the maintenance error is changed
to threshold value 2 after performing recovery from the maintenance error.
After the threshold value (2) is enabled, the warning; to notify the possibility of ink
leakage out of the printer, is displayed every time the waste ink counter increases by
1%.
If the waste ink counter reaches the threshold value (2), the maintenance error occurs.
Then, the waste ink counter is changed back to the threshold value (1) after recovering
from the maintenance error, and the warning is displayed repeatedly according to the
increment of the waste ink counter until the maintenance error occurs when the
threshold value (2) is reached.
(Recovery from the maintenance error can be performed up to the specified number
of times.)

To measure the manufacturing variations of the DC motors (CR Motor/PF Motor), Main Board and Power
Supply Board to determine the correction value used for estimating the current values of the motors.
Risks if the
adjustment is not
correctly made
The printer cannot measure the current value of motor correctly, then the heat generation caused by motor
drive cannot be estimated accurately either, and which may results in trouble such as incorrect control of
motors when allotting a cool down period according to each heat generation.
In the worst case, excessive heat generation may cause smoke or ignition.
Procedure
1. Select from the menu of the Adjustment Program. Check the check box of the replaced parts and press the
Execute button to measure the correction value.
2. The correction value is automatically measured and the measurement value is written to the EEPROM on
the Main Board.

Revision A
To measure the manufacturing variation of the DC motor (Scanner) to determine the correction value used for
estimating the current value of the motor.
Because the printer cannot measure the current value of the motor accurately, even if just a mechanical load
with which the Scanner Carriage can operate without any problem is applied, the printer cannot control the
drive of the motors correctly, which may result in occurrence or generation of scanner fatal error, vibration, or
noises.
Procedure
1. Select from the menu of the Adjustment Program and press the Perform button to measure the correction
value.
2. Turn off the printer and turn it back on.
After the Scanner Carriage is operated, the correction value is automatically measured and the measurement
value is written to the EEPROM on the Main Board.
3. Press the Check button to confirm the written value in the EEPROM is within the standard range.

4.1 Overview
This section provides information to maintain the printer in its optimum condition.
4.1.1 Cleaning
Except for the Printhead, there are no other mechanical parts or units that require periodic cleaning. However, if
need arises, clean the component observing the following instructions.
Instructions for cleaning
Exterior parts such as housing
Wipe dirt off with a soft clean cloth moistened with water. For glossy or transparent parts, use of unwoven cloth is
recommended to avoid scratching those parts.
Inside of the printer
Remove paper dust with a vacuum cleaner.
Rubber or plastic rollers such as an LD roller used to feed paper
If paper dust adhered to the rollers decreases the frictional force of the rollers and the rollers cannot properly feed
paper, wipe off the paper dust with a soft cloth moistened with diluted alcohol.
Do not use alcohol for cleaning the transparent parts. Doing so may cause them to get
cloudy.
When wiping paper dust off the LD Roller, be careful not to rub against the surface
asperity.
To minimize the effect on the parts, use diluted alcohol such as 70% diluted ether.
After using alcohol for cleaning, make sure to wipe the part off with a soft dry dust-free
cloth to remove alcohol traces fully.
4.1.2 Lubrication
The type and amount of the grease used to lubricate the printer parts are determined based on the results of the
internal evaluations. Therefore, refer to "4.2 Lubrication Points and Instructions (p75)" for the repairing
procedures below, and apply the specified type and amount of the grease to the specified part of the printer
mechanism.
"4.2 Lubrication Points and Instructions (p75)" also provides information about whether or not the parts which
require lubrication are supplied as ASP and the lubrication status when supplied as ASP. For the parts which are
not supplied as ASP, if their movement is not smooth enough, check their lubrication status and lubricate them if
necessary.

Method
In order to prevent damaging the Change Lever, the CR Unit should be secured at the
position indicated in Step 2. Therefore, when securing the CR Unit with strong tape, hold
the Timing Belt to keep the position of the CR Unit as is and avoid the CR Unit from
moving to the 0-digit side.
When securing the CR Unit of the multifunction printer, attach the strong tape so that the
gap between the strong tape and ink replacement label attached on the Housing Right is 2
1 mm.
1. Turn off the printer to set the CR Unit to its home position.
2. Pull the CR Timing Belt, and move the CR Unit to the 80-digit side slightly so that the CR Unit can touch
the side of the tip on the Change Lever.
3. Attach the not-folded end of strong tape on the bottom of the CR Unit.
4. Attach the strong tape on to the Housing Right, and secure the CR Unit.
