Disassembly and Assembly Overview 10

EPSON Stylus C63/64/83/84 Revision A

1.2 Caution regarding assembling/disassembling
of the printer mechanism, and how to ensure
of quality on re-assembled product

On current low end models, we basically forbided to remove Housing (Lower) from
Printer mechanism in your repair. This is because there is a possibility of main frame
deformation when a part (such as Ink system) is removed from Printer mechanism
without Housing (Lower).
Therefore, if you want to replace Ink system/PF motor, we reco mmend to replace with
new Printer mechanism w i th Housing (Lower).

On these models, you have to remove Housing (Lower) from printer mechanism when
replacing [Porous Pad] with new one.
Therefore, we clarify caution regarding assembling/disassembling of the printer
mechanism without Housing (Lower), and how to ensure of quality on repaired
productsin this section.

[Caution regarding assembling/disassembling of the printer mechanism]

1) Main frame
(a) Control of assembled standard position.
[Reason]
The assembed accuracy of each part composed of Printer mechanism is
based on Housing (Lower).
[Service treatment]
Confirm that there is no gap between main frame and Housing (Lower).
[Reference]
To ensure the assembled accuracy, you have to control the assembled
standard position of main frame against X/Y/Z-axis direction.
[X-axis direction]

- Make sure that main frame is correctly placed on the groove of Housing
(Lower).

- Make sure that there is no gap between main frame and Housing (Lower).
[Y-axis direction]
Make sure that cut-out portion of main frame is correctly placed on the
square protrusion of Housing (Lower).
[Z-axis direction]

- Make sure that there is no gap between main frame and Housing (Lower).

- Make sure that the left side of Printer mechanism is correctly fixed by
two hooks.

(b) Control of vertical level of guide rail (Guide rail means the portion latched by
hooks of IC holder & Print head assy..)
[Reason]
There is a possibility that printing failre/operation failure occurs by guide rail
deformation.
[Service treatment]

- Do not remove [Mounting Plate, M/B] from Printer mechanism.

- Hold up the specified position of main frame to avoid the deformation.
(c) How to assemble of ASF unit/Circuit board/Paper guide upper

[Reason]
There is a possibility that main frame deformation is caused extra force in
assembling. As the result, printing failre/operation failure occurs.
[Service treatment]
Hold the opposite side by by hand while you are installing the above parts.

2) Front frame
(a) Control of vertical level
[Reason]
There is a possibility that printing failre occurs by front frame deformation.
[Service treatment]
Handle Front frame in assembling/disassembling carefully.

3) IC holder
(a) Handling of IC holder
[Reason]
If IC holder is damaged in assembling/disassembling of your repair, there is a
possibility that vital problem occus in user’s futher operation.
[Service treatment]
Released two hooks of IC holder from the inside of IC holder by the tweezer.

[How to ensure of quality on re-assembled product]
We judge that the quality of re-assembled product is ensured if there is no problem
about the print result by adjustment program..

MAINTENANCE

CHAPTER

EPSON Stylus C63/64/83/84 Revision A

3.1 Overview

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

3.1.1 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 I O N

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.

n Be careful not to damage any components when you clean inside

the printer.

n Do not scratch the coated surface of the PF roller. Use soft brush

to wipe off any dusts. Use a soft cloth moistened with alcohol to
remove the ink stain.

n Do not use cleaning sheet included in the media for normal usage.

It may damage the coated surface of PF roller.
If the adhesive surface of the cleaning sheet is set to the LD roller
shaft side and used to clean the LD roller surface, it is no
problem.

3.1.2 Service Maintenance

If any abnormal print (dot missing, white line, etc.) has occurred or the p rinter indicates
the "Maintenance request error" (This error is displayed as "Maintenance call error" in
the STM3), take the following actions to clear the error.

o Printhead cleaning

When dot missing or banding phenomenon has occurred, you need to perform the
printhead cleaning operation
function can be performed by the control panel operation, the printer driver utility
and the Adjustment program.
In case that the cleaning sequence is performed by the control panel operation,
confirm that the printer is in stand-by state (the Power LED is lighting), and hold
down the Error reset button on the control panel for more than 3 seconds. Then,
the printer starts the cleaning sequence (the Power LED blinks during this
sequence).
In case that you select and perform the manual cleaning by the printer driver
utility, the most appropriate cleaning mode is selected. The following is the
process to perform the printhead cleaning from the printer driver utility.
As for the operation of the Adjustment program, refer to Chapter 5 Adjustment.

*1: The Stylus C63/C64/C83/84 has four modes for manual cleaning, and even
during printing, the appropriate cleaning mode is automatically selected and
performed according to variou s conditions. Th erefore the ink co nsumption am ount
for manual cleaning varies depending on each mode.

*1

by using the printhead cleaning function. This

o 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.

o Inside the printer

Use a vacuum cleaner to remove any paper dust.

o LD Roller

When paper loading function does not operate because friction of the LD roller is
lowered by any paper dust , set t he adhesive s ide up of t he cleanin g sheet (incl uded
in the media) to remove any paper dust. Repeat loading the cleaning sheet several
times.

Maintenance Overview 41

EPSON Stylus C63/64/83/84 Revision A

1. Select the “EPSON Status Monitor 3” in the printer driver utility, and make sure
that the printer is in stand-by state by using the Status monitor 3. If the printer is in
stand-by state, the following figure is indicated on the monitor.

Figure 3-1. Status monitor 3 indication

2. Select the “Head Cleaning” in the printer driver utility, and perform the printhead
cleaning. After performing the printhead cleaning operation, print a nozzle check
pattern by selecting the “Nozzle Check“. If you repeat the printhead cleaning
operation without selecting the “Nozzle Check”, CL1, the weakest cleaning, will
be repeated.

Maintenance request error (Maintenance call error)

o

Ink is used for the printhead cleaning operation as well as the printing operation.
When the ink is used for the printhead cleaning op erat ion, the ink is drained to the
Waste drain ink pad and 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 (Waste ink counter = Protection counter A = 47000
points (C83/C84), 25000 points (C63/C64)) of the absorbing capability of the
Waste drain ink pad, the Maintenance call erro r is indicated on Status moni tor 3 as
following figure.

Figure 3-3. Maintenance error indication in STM3

In this case, replace to new Waste drain ink pad and clear the waste ink counter stored
into the EEPROM. The waste ink counter can be reset only from the Adjustment
program because this printer dose not have the waste ink counter reset function by the
control panel SW. As for the procedure, refer to Chapter 2 Adjustment.
In your repair activity, check the waste ink counter along with the firmware version,
Main board checker program version and nozzle check pattern on the nozzle check
pattern printing. If the waste ink counter is closed to its limit, recommend that the
Waste drain ink pad will be replaced with new one. This is because the "Maintenance
request error" will may occur after returning the repaired product to the customer.
