 NO:

Do not check the paper width and top edge of the paper. The printer continues to print even if the paper width
does not match the data width, and the printer may print beyond the paper. Because this soils the inside of the
printer, we recommend you select ON. This may result in a wider blank margin at the top of each page.

A paper align error does not occur even if the printed data is out of range of the paper, and the printer continues
to print.

When you select ON, the printer prints the nozzle check pattern before printing each print job or the 10th sheet,

Because the vacuum fan is not operating properly, the paper is not held flat during
printing.

Drying ink is insufficient. Raise the heater temperature and make the print again.

There is a foreign material or dirt absorbing ink around the PRINT HEAD(s). Check around the PRINT HEAD(s) for a dirt or foreign material, and remove it if

The paper is buckling. Re-load the paper once the set heater temperature is reached.

The color dots are smearing and mixing into each-other. The ink dots dry too slowly: try increasing the heater temperature.

Turn on the printer in the serviceman mode, and check whether the VACUUM
FAN(s) operates normally (p.234). If any abnormality is found, check the
connection status and replace the defective VACUUM FAN if necessary.

Symptom Description Remedy/Points to be checked

Ink smear (backside) The backside of the paper is contaminated by ink smear in the paper feed path. Check the platen and PRESSURE ROLLER(s) for ink smudges, and clean them if

any dirt is observed.

If the PAPER SIZE CHECK in the PRINTER SETUP menu has been
set to OFF, the printer will print on the platen which results in the ink
smear, so be careful.

The ink does not have enough time to dry before it is rolled on the Take-up Reel. Try increasing the drying time between the passes, increasing the heater

temperature or put a fan in front of the printer to dry the media before it gets rolled­up.

Horizontal banding Paper setting made in the custom paper menu is wrong. Correct the paper setting of the custom paper menu.

There is something wrong with paper feeding. Carry out the Paper feed adjustment (p.223).

Check the PF ENC SCALE for scratch, contamination, and correct it if any .
Check the PF ENCODER ASSY for contamination, and clean it if needed.

Replace the PF ENCODER ASSY (p.123).
The PRINT HEAD(s) has not been adjusted properly. Carry out the Head slant adjustment ( p.212).
The PF belt’s tension is not proper. Carry out the PF reduction belt tension adjustment (p.222).
The parameter settings of the NVRAM may be incorrect if the banding occurs right

after replacing the MAIN BOARD ASSY.
The print head has a defect. Replace the PRINT HEAD(s) (p.158).
There are too much blanks between the color dots. The ink dots may be drying too fast: try lowering the heaters temperature settings.

Vertical banding Adjustments have not been carried out properly. Carry out the head Uni-D/Bi-D Low/High gap adjustment (p.219).

Import the NVRAM parameters from the old MAIN BOARD ASSY.

The carriage unit cannot move smoothly. Check the CR BELT and the drive pulley for a defect.

Check whether the CR MOTOR is correctly installed. If not, install it correctly.

DISASSEMBLY & ASSEMBLY

CHAPTER

Confidential

Epson Stylus Pro GS6000 Revision F

W A R N I N G

4.1 Overview

This chapter describes procedures for disassembling the main components of Epson
Stylus Pro GS6000. Unless otherwise specified, disassembled units or components can
be reassembled by reversing the disassembly procedure.

 WARNING

Procedures which, if not strictly observed, could result in personal injury are
described under the heading “WARNING”.

 CAUTION

“CAUTION” signals a precaution which, if ignored, could result in damage to
equipment.

 CHECK POINT

Important tips for procedures are described under the heading “CHECK POINT”.

 REASSEMBLY

If the assembly procedure is different from the reversed disassembly procedure,
the correct procedure is described under the heading “REASSEMBLY”.

 ADJUSTMENT

Any adjustments required after reassembly of components or parts are described
under the heading “ADJUSTMENT REQUIRED”. Be sure to perform the
specified adjustments with reference to Chapter 5 “ADJUSTMENT”.

When you have to remove any parts or components that are not described in this
chapter, refer to ?7.3 Parts List? (p262) in the Appendix.

The illustrations of this Service Manual have been made with a sample unit so the color
of some parts (lever handles, carriage cover, etc.) is different from the mass production
units.

4.1.1 Precautions

Before starting the disassembly or reassembly of the product, read the following
precautions given under the headings “WARNING” and “CAUTION”.

 When the Front Cover is opened, a safety-interlock mechanism

causes the CR MOTOR and the PF motor to stop. Never
disable the interlock function for operator protection.

 This printer is equipped with a lithium battery. When handling

the lithium battery, the following precautions should be
followed.

• When replacing the battery, replace only with a specified

type of battery. Using a different type of battery may cause
excess heat or explosion.

• Dispose of used batteries according to manufacture’s

instructions and local regulations. Contact your local
government agency for information about battery disposal
and recycling.

• When disposing of the battery, be sure to securely cover its

(+) end with tape to prevent combustion or explosion.

• Do not recharge the battery.

• Do not use the battery if it is discolored or damaged, or if any

leakage of electrolyte is observed.

• Do not dismantle, solder or heat the battery. Doing so could

result in leakage of electrolyte, heat generation, or explosion.

• Do not heat the battery or dispose of it in fire.

• If the electrolyte leaked from the battery gets in contact with

your skin or gets into your eyes, rinse it off with clean water
and see a doctor immediately.

 The power switch is installed on the secondary side of the

power circuit, so power is always supplied unless the power
cord is unplugged. Unless otherwise stated, be sure to unplug
the power cord and wait at least for one minute and 30 seconds
before disassembling or assembling the printer to prevent
electric shock and damage to the circuit.

 Always wear gloves for disassembly and reassembly to avoid

injury from sharp metal edges.

 If ink gets in your eye, flush the eye with fresh water and see a

doctor immediately.

 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 irritation occurs, contact a physician.

 Make sufficient work space for servicing.
 Locate the printer on a stable and flat surface.
 The ink-path-related components or parts should be firmly and

securely reinstalled on the printer to prevent ink leaking.

 Use only recommended tools for disassembly, assembly or

adjustment of the printer.

 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.

 Apply lubricants and adhesives as specified.
 Be careful not to soil the printer or the floor with leaked ink

when removing the ink-path-related components or parts.
Spread a sheet of paper or cloth on the floor in advance.

 Do not touch electrical circuit boards with bare hands as the

elements on the board are so sensitive that they can be easily
damaged by static electricity. If you have to handle the boards
with bare hands, use static electricity discharge equipment such
as anti-static wrist straps.

 When reassembling the printer, make sure to connect the

connectors of the electric components or parts correctly and
securely. Use extreme care when connecting FFCs (flexible flat
cables). Improper connection of the FFCs, such as inserting
them diagonally into the connectors, could cause short­circuiting and lead to breakdown of the electric elements on the
boards.

 When reassembling the printer, make sure to route the FFCs

and other cables as specified in this chapter. Failure to do so
may cause an unexpected contact of the cables with sharp metal
edges, or lead to lower the noise immunity.

 When the printer has to be operated with the covers removed,

take extra care not to get your fingers or clothes caught in
moving parts.

 When you have to remove any parts or components that are

provided as after-service-parts but are not described in this
chapter, carefully observe how they are installed and make
sure to remember it before removing them.

 When you removed any parts (especially cables) that are

secured with acetate tape or two-sided tape, be sure to reinstall
and secure them with the tape as exactly the same as they were.

 Disassembling the frame and some components of the printer is

prohibited because they are assembled with precise
measurements in 1/100 mm unit at the factory. (See example p.

96 and p. 103.)

 When replacing the MAIN BOARD ASSY, P/S BOARD ASSY

and harnesses, be sure to check visually if the harnesses are
caught or there is any connection failure.

4.4 Disassembly and Assembly Procedure

This section describes procedures for disassembling the components allowed to be
disassembled. Unless otherwise specified, disassembled units or components can be
reassembled by reversing the disassembly procedure.

4.4.1 Basic Operations

4.4.1.1 Unlocking the Carriage

1. Push and open the MAINTENANCE COVER ASSY (right only). See Figure

4-26.

2. Insert your hand between the Carriage and the frame as shown in the figure below.

3. Push the lock pin to the rear to unlock the Carriage.

4. Push the Carriage to the center.

4.4.1.2 Disposal of Waste Ink

Dispose of waste ink when the ink drain tank is more than half full or when DRAIN
TANK FULL is displayed on the LCD panel.

The waste ink from the printer is industrial waste. It is required to
carry out proper waste ink disposal in compliance with the
industrial waste disposal laws and ordinances of your local
government. Consign disposal of waste inks to an industrial waste
disposer. (At this point, provide the Waste Ink Data Sheet to the
industrial waste disposer, if necessary. You can download it at your
local Epson Web site.)

1. Prepare an empty container to collect the waste ink.

2. Lay a protective material on the floor under the ink drain tank.
