original. The zoom ratio is determined as follows, and the same ratio is
applied to both horizontal and vertical sides.
• Detects the image size of the original using the preview function.
• Calculates an appropriate zoom ratio from the image size and the
printable area of the paper.
• If the ratio falls into less than 25%, 25% is applied. 400% is applied
if over 400% likewise.
• For color/B&W copying, the zoom ratio is determined so as to
make a copy of the whole image of the original on the paper.
• For photo copying, the zoom ratio is determined so as not to leave
any margins on the paper.

Making 20 (fixed value) copies in color/B&W becomes available by operating specific
keys (Refer to p. 18). In this copying, the second copy or later are carried out without
scanning by storing the scanned data in the memory to makes copying faster. However,
if the scanned data is bigger than the memory’s capacity, scanning will be repeated for
each copy. The conditions that the scanned data can be stored in the memory are as
follows.

3.1 Overview

3.1.2 Preliminary Checks

This chapter describes how to solve problems.

Before starting troubleshooting, be sure to verify that the following conditions
are all met:

W A R N IN G

„
„
„

C H E C K
P O IN T

„

„

Be careful to avoid electric shocks when checking the electrical
circuit boards (MAIN and PSE/PSB boards) while the power is
turned on.
Touching an FET, transistor or heat sink with one hand while
touching a metal part of the mechanism with the other hand
could result in an electric shock, so carefully avoid this.
After initial filling of ink has been repeated several times,
immediate moving or tilting of the printer could result in
leaking of ink that has not been completely absorbed by the
Waste Ink Pad. When initial filling of ink has been repeated
several times, check the ink remaining in the tip of the Waste
Ink Tube and the waste ink not absorbed by the Waste Ink Pad
before moving the printer.
Disassembly and reassembly of parts is often required when
identifying the causes of problems. The parts should be
disassembled and re-assembled correctly while referring to
“DISASSEMBLY/ASSEMBLY” (p.54) so that the operation
and status of each check item can be correctly verified.
Some individual part and units may require adjustment once
they are removed or replaced. If removing or replacing parts
which have specific instructions for adjustment included in
“DISASSEMBLY/ASSEMBLY” (p.54), be sure to make these
adjustments after repairing the problem location.

3.1.1 Specified Tools
This printer does not require any specified tools for troubleshooting.

TROUBLESHOOTING

† The power supply voltage must be within the specification limits. (Measure the
voltage at the wall socket.)
† The power code must be free from damage, short circuit or breakage, or miswiring
in the power code.
† The printer must be grounded properly.
† The printer should not be located in a place where it can be exposed to too high or
low temperature, too high or low humidity, or abrupt temperature change.
† The printer should not be located near waterworks, near humidifiers, near heaters
or near flames, in a dusty atmosphere or in a place where the printer can be
exposed to blast from an air conditioner.
† The printer should not be located in a place where volatile or inflammable gases
are produced.
† The printer should not be located in a place where it can be exposed to direct rays
of the sun.
† The printer must be placed on a strong and steady level table (without an
inclination larger than five degrees).
† Any vibrating equipment must not be placed on or under the printer.
† The paper used must conform to the specification.
† There is no error in handling of the printer.
† Check the inside of the printer, and remove foreign matters if any, such as paper
clips, staples, bits of paper, paper dust or toner.
† Clean the inside of the printer and the rubber rolls.

6.1 Overview

6.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates
the “Maintenance request error” (This error is displayed as “Service Required” in the
STM3), take the following actions to clear the error.

This section provides information to maintain the printer in its optimum condition.

6.1.1 Cleaning
This printer has no mechanical components which require regular cleaning except the
Printhead. Therefore, when returning the printer to the user, check the following parts
and perform appropriate cleaning if stain is noticeable.
C A U T IO N

„

„
„
„
„

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 or deteriorate the
components of the printer.
Be careful not to damage any components when you clean
inside the printer.
Do not scratch the coated surface of the PF roller. Use a soft
brush to wipe off any dusts.
Use a soft cloth moistened with alcohol to remove the ink stain.
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.

† Exterior parts
Use a clean soft cloth moistened with water, and wipe off any dirt. If the exterior
parts are stained by the ink, use a cloth moistened with neutral detergent to wipe it
off.

6.1.2.1 Printhead cleaning
When dot missing or banding phenomenon has occurred, you need to perform the
Printhead cleaning operation* by using the Printhead cleaning function. This function
can be performed by the control panel operation, the printer driver utility and the
Adjustment program.
* : Epson STYLUS NX100/NX105/SX100/SX105/TX100/TX101/TX102/TX103/
TX105/TX106/TX109/ME 300 have three modes for manual cleaning, and even
during printing, the appropriate cleaning mode is automatically selected and
performed according to various conditions. Therefore the ink consumption amount
for manual cleaning varies depending on each mode.

6.1.2.2 Maintenance request error
Ink is used for the Printhead cleaning or cap flushing operation as well as the printing
operation. When the ink is used for the Printhead cleaning or flushing operation, the
ink is drained via the pump to the Waste ink pads. The amount of the waste ink is
stored as the waste ink counter into the EEPROM on the Main Board. Due to this,
when the waste ink counter has reached the limit of the absorbing capability of the
Waste ink pads, the Maintenance call error is indicated on Status monitor 3. However,
the limit value of the waste ink counter varies according to the usage.

† Inside the printer
Use a vacuum cleaner to remove any paper dust.
† LD Roller
When paper loading function does not operate because friction of the LD roller is
lowered by any paper dust, use a soft cloth moistened with alcohol to remove the
paper dust.

MAINTENANCE

Revision A

C H E C K
P O IN T

Refer to following chapter about indication of the maintenance
request error.
„ Chapter 3 TROUBLESHOOTING (p.27)

When the maintenance request error has occurred, replace the waste ink pad with new
one and clear the waste ink counter stored into the EEPROM. If the waste ink counter
is closed to its limit, we recommend to replace the Waste ink pad with new one. This is
because the Maintenance request error will may occur after returning the repaired
product to the customer.
