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
8. When disassembling or assembling this product, make sure to wear gloves to avoid injuries from metal parts
with sharp edges.
9. Use only recommended tools for disassembling, assembling or adjusting the printer.
10. Observe the specified torque when tightening screws.
11. Be extremely careful not to scratch or contaminate the following parts.
Nozzle plate of the printhead
Ink Supply Unit
CR Scale
PF Scale
Coated surface of the PF Roller
Gears
Rollers
LCD
Exterior parts
12. Never use oil or grease other than those specified in this manual. Use of different types of oil or grease may
damage the component or give bad influence on the printer function.
13. Apply the specified amount of grease described in this manual.
14. Make the specified adjustments when you disassemble the printer.
15. When cleaning this product, follow the procedure described in this manual.
16. 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.
17. Make sure to install antivirus software in the computers used for the service support activities.
18. Keep the virus pattern file of antivirus software up-to-date.

1.3 Detailed Disassembly/Reassembly Procedure for each Part/Unit
Rear Housing
Be careful not to damage the hooks (x2), dowels (x2) and ribs (x8)
that secure the Rear Housing.
Left / Right Cover
Remove the Left/Right Cover carefully not to damage the hooks
(x2 each) and ribs (x3 each) that secure the Left/Right Cover.
When removing the Left/Right Cover, slide it in the direction of the
arrow shown above while slightly pushing the section A.
Left / Right Decoration Plate
Be careful not to damage the ribs (x3 each) that secure the Left/
Right Decoration Plate and hooks (x4) of the Lower Housing.
Stacker Assy
Be careful for ink to flow out then because if tilting is too soon after
the initial ink charge or a similar situation, the ink still on the Waste
Ink Pad which is not yet absorbed flows over out of the printer.
Upper Housing Support Assy (w/Panel Unit)
Disconnect the Panel FFCs (x2) from the connectors on the Panel Board before removing the Upper Housing Support Assy.
Be careful not to damage the hooks (x4) that secure the Upper Housing Support Assy.
Be careful to remove the Upper Housing Support Assy because the I/C Holder Unit Cover Open Sensor Cable is connected to the sensor on the
Disassembly/Reassembly Detailed Disassembly/Reassembly Procedure for each Part/Unit 19
back of the Upper Housing Support Assy.
Pull out the Panel FFCs(x2) from the hole of the Upper Housing Assy before removing the Upper Housing Assy.
Tighten the screws in the order indicated in the figure above.

When installing the LCD Mounting Plate, make sure the LCD is
located inside the protrusions (x3) of the LCD Mounting Plate, and
then secure the plate with the screws.
Decomp Pump Assy
Install the Panel Shield Plate under the protrusion of the Panel
Buttons as shown above. Make sure that the plate contacts the
Housing Support reinforcing plate, and secure it with the screw.
Tighten the screws in the order indicated in the figure above.

Disassembly/Reassembly Detailed Disassembly/Reassembly Procedure for each Part/Unit 20
When installing the Waste Ink Tube/Waste Ink Pads (x10),
confirm the shapes of them and install them in the order shown
above.
When installing the Waste Ink Tube, route it through the
groove of the Waste Ink Pads, and insert the end of the shorter
tube to the section A and longer one to the section B.
When connecting the Decomp Tube to the joint of the I/C
Holder Unit, make sure the gap between the end of the Decomp
Tube to the base of the joint is 1 mm or less, and then secure
the tube with the hooks (x2).
Route the Decomp Tube through the groove of the Lower
Housing and secure the tube with the hook.
When installing the APG Assy, align the marks on the Spur
Gear,14.4 and PG Cam Left to match their phases as shown
above.
Tighten the screws in the order indicated in the figure above.
When installing the Ink Tube Holders (x2), install them on the
locations where the acetate tape (x2) is attached on the Ink Tube.

Printhead / Printhead Mounting Plate
Do not use the electric screwdriver when installing the Printhead
and/or the Printhead Mounting Plate. Doing so applies extra force
when tightening the screw and affects the platen gap.
When installing the Printhead, follow the procedure below.
1. Temporarily tighten the screws (x3) and loosen them half turn.
2. Press the Printhead to the rear of the printer, and tighten the
