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.

MAINTENANCE
Confidential
L200/L201/L100/L101 Revision A
3.1 Overview
This section provides information to maintain the printer in its optimum condition.
3.1.1 Cleaning
Except for the printhead, there are no other mechanism 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.
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 Points and Instructions (p39)” for the repairing
procedures below, and apply the specified type and amount of the grease to the specified part of the printer
mechanism.
Before applying the grease, make sure to wipe off old grease completely with BEMCOT.
