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
with sharp edges.
11. Use only recommended tools for disassembling, assembling or adjusting the printer.
12. Observe the specified torque when tightening screws.

damage the component or give bad influence on the printer function.
15. Apply the specified amount of grease described in this manual.
16. Make the specified adjustments when you disassemble the printer.
17. When cleaning this product, follow the procedure described in this manual.
18. When transporting this product after filling the ink in the printhead, pack the printer without removing the
ink cartridges in order to prevent the printhead from drying out.
19. Make sure to install antivirus software in the computers used for the service support activities.
20. Keep the virus pattern file of antivirus software up-to-date.
21. When disassembling/reassembling this product, if you find adhesive power of the double-sided tape which
secure the parts or FFC is not enough, replace the tape with new one and attach it correctly to the specified
points where the parts or FFC should be secured.

3.1 Required Adjustments
The table from the following page 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.
„ 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 replacing the Main Board and the Printer Mechanism at the same time, the
adjustment should be made after performing the initial setting.
„ The table items and marks used in the “Required Adjustment List” provided on the
following pages have the following meanings.
• “---” indicates that the adjustment is not required.
• The “Mechanism Adjustment” should be performed just after reinstalling or
reassembling the part or unit.
• The “Adjustments using the Adjustment Program” need to be performed after
reassembling the printer completely.
„ 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.

the same way as performed in the traditional procedure, the nozzle surface may be
damaged. When performing the PG Adjustment or checking the platen gap, make sure
to apply Teflon tape (thickness: 0.08 mm) on all the thickness gauges used for the
adjustment or check in advance.
„ Use commercially available Teflon tape of 0.08 mm in thickness.
„ When applying Teflon tape on the thickness gauges, make sure no bubbles or foreign
material remain under the tape.

„ 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 Pickup 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 Pickup Roller/Middle 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
