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. In order to protect sensitive microprocessors and circuitry, use static discharge equipment, such as anti-static
wrist straps, when accessing internal components.
6. 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.
7. 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.
Confidential

Revision F
2.1 Required Adjustments
 When the EEPROM Data Copy cannot be made for the Main Board that needs to be replaced, the
Waste Ink Tray Assy must be replaced after replacing the Main Board with a new one.
 After all required adjustments are completed, use the “Final check pattern print” function to
print all adjustment patterns for final check. If you find a problem with the printout patterns,
carry out the adjustment again.
 When using a new Main Board for replacing the Printer Mechanism, the Initial setting must have
been made to the Main Board.
The table below lists the required adjustments depending upon the parts being repaired or replaced. Find the part(s) you removed
or replaced, and check which adjustment(s) must be carried out.
Note: <Meaning of the marks in the table>
“O” indicates that the adjustment must be carried out. “O*” indicates that the adjustment is recommended. “---” indicates that the adjustment is not required. If you have
removed or replaced multiple parts, make sure to check the required adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry out
them in the order given in the “Priority” row.
In this chapter, the product names are called as follows:

2.2 Revision FDetails of Adjustments
This section provides adjustment procedures for which explanation in details is necessary. See " 2.1 Required
Adjustments (p24)" for the adjustments not explained here.
2.2.1 TOP Margin Adjustment
Three adjustment patterns are printed on the top of the paper as shown in Figure 2-1.

How to Judge
Check if the top edge of the paper is within -3 to +3 steps from the standard line.
Additional Information
If it is not within the OK range, select the adjustment value (-4 to +4 steps) on the adjustment program to adjust the top edge
of paper until it becomes within -3 to +3 steps from the standard line. Then, print the adjustment pattern again to check the
result.
 The patterns are printed on three sections. If those three patterns
are in different position to the top edge of paper, the paper was
fed on a skew. Set the papers correctly and print it again to
adjust the top margin correctly.
 The following pattern is printed with the optimal adjustment
value.

3.1 Overview
This section provides information to maintain the printer in its optimum condition.
In this chapter, the product names are called as follows:
 NX125 series: Epson Stylus NX125/NX127/TX120/TX125/TX123/SX125/TX121/TX121x/
TX129/Epson ME 320/ME 330/ME 350
 T13 series:
Epson Stylus T13/T13x/T12/N10/N11/T22/T25/S22/T22E/
Epson ME 10/ME 32/ME 33/ME 35
 NX130 series: Epson Stylus NX130/TX130/TX133/TX135/SX130/Epson ME 340
3.1.1 Cleaning
Except for the printhead, there are no other mechanism components 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 parts with glossy surfaces 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.
 Instructions for cleaning ink stains
Wipe the stains off with a cloth wrung out of 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.
3.1.2 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 " 3.2 Lubrication Point (p29)" for the repairing procedures below, and
apply the specified type and amount of the grease to the specified part of the printer mechanism.
