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, fo r 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.

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.

This section provides information to maintain the printer in its optimum condition.
In this chapter, the product names are called as follows:

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.

Carriage/PF roller
movement and position

2. Seeking the home position
2-1.The carriage moves to the 80-digit side slowly and confirms it touches the CR lock.
2-2.The carriage moves to the 0-digit side slowly to leave from the CR lock.
2-3.Checks if paper does not exist with the PE sensor and the PF Motor rotates clockwise to release the CR lock.
2-4.The carriage moves to the 80-digit side slowly and confirms that the CR lock is released.
2-5.The carriage quickly moves to the 80-digit side by the Left Frame.
2-6.After the carriage continuously moves to the 80-digit side slowly and confirms it touches the Left Frame, sets the
distance from the home position to the Left Frame as the theoretical value.
2-7.The carriage quickly moves to the 0-digit side and slows down as it gets to its home position, and stops there.
3. Low temperature operation sequence
3-1.The carriage moves back and forth between the 0-digit side and the 80-digit side for two times.
