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

disassembly/reassembly procedures.
Table 1-1. List of Tools
1.1.2 Checks and Precautions before Disassembling
1.1.2.1 Factors which Affect the Print Quality
HOW TO PLACE THE INK TANK ASSY WHEN DISASSEMBLING/
REASSEMBLING
The film under sealing film attached on the Ink Supply Tank Assy of this
printer is ventilation film. The ink in the ink tanks is vented to atmosphere
through this film to keep ink supply to the Printhead stable. If the film gets wet
with ink, the ink in the tanks is not properly vented and printing may not be
capable.
In order to prevent this from occurring, make sure to place the Ink Supply Tank
Assy as shown below after removing it.

DISCHRGING INK FROM THE INK SUPPLY TANK
Discharging ink is recommended only when disconnecting the Ink Supply Tank
Tube Assy from the Ink Supply Tank. Before performing the above
disconnection, discharge ink from the Ink Supply Tank as follows.
Necessary tools
• Containers (x 6) for each discharged ink
• Injector (with a tip of φ3.2 mm)
• Tube (capable to be connected to the joint)

P O I N T
Discharging procedure
The photos in the following procedure are for L200/L201, but
the procedure for L800/L801 is the same; the numbers of the
tube and the location of the Ink Supply Tank Assy in the
photos are different from those of L800/L801, though.
Prior to the following steps, connect the injector with the tube,
and then discharge ink according to the procedure.
1. Remove the Housing Upper Assy. (p. 25)
2. With the choke value closed (p.11), place the Ink Supply Tank Assy on a
place where its bottom is higher than the top of the Printhead.
3. Prepare a container for ink to discharge, then disconnect the Ink Supply
Tube from the joint and put its tip into the container for the ink.

Table 2-2. Maintenance Items
Maintenance Item
Head cleaning
Maintenance counter
Ink charge
Small ink counter reset
This function is used to execute Cleaning efficiently when ink is not
delivered from the Head properly, e.g. dot missing.
The printer causes a maintenance error when the maintenance counter
(for the Waste Ink Tray, Waste Ink Pad Lower) reaches its maximum.
Use this to reset the counter after replacing the Waste Ink Pad and Waste
Ink Pad Lower, and use this to reset the ink tube counter when replacing
the Ink Supply Tube. If you find the counter is close to the maximum
during servicing, carry out the pad replacement and the counter reset to
avoid the printer returned from the user due to the maintenance error.
This function is used to charge ink to the components composing the ink
path such as Printhead after replacing them.
When an ink out error occurs even though some ink is still in the Ink
Supply Tank Assy (in the case when the ink counter in the printer and the
actual ink remaining amount do not match), this function can decrease
the ink counter (resetting the counter partially) to adjust the counter with
the actual ink remaining amount.
Purpose Method Outline Tool
The cleaning can be selected from the normal cleaning or the power
cleaning. Whether to reflect the discharged ink amount to the waste ink
pad counter or not can also be selected as an option. The head cleaning is
performed automatically. After the cleaning, print a nozzle ch
to check if all nozzles are firing ink properly.
Select the replaced parts, and reset the corresponding counters.
The ink charge can be selected from the charge to Printhead only or the
charge through Ink Tube, Adapter to Printhead. Whether to reflect the
discharged ink amount to the waste ink pad counter or not can also be
selected as an option.
Select the range to charge ink and options, and then press the execute
button to execute the ink charge to the selected range automatically.
After ink charge, print a nozzle check pattern to check if all nozzles are
firing ink properly.
If the execute button is pressed, the ink counter value is automatically
set. But if no ink out error is occurring, the message which says the
function cannot be executed appears and no reset will be made.

2.2 Using the Adjustment Program
This section describes how to judge the adjustment patterns printed by the
Adjustment Program. For information on how to operate the Adjustment
Program, see the instructions displayed by the Adjustment Program.
2.2.1 Top Margin Adjustment
Patterns are printed as shown below.
[Judging Standard]
The distance from a paper top edge to a line is:
• 4 mm or more: Choose the “-” from a combobox.
• 2 mm or less: Choose the “+” from a combobox.
Figure 2-1. Top Margin Adjustment Pattern
How to Judge
Measure the distance from the top edge of paper to the printed line, and enter
any one of the “-”, “0”, “+” according to the judging standard.
2.2.2 Head Angular Adjustment
Two patterns are printed as shown below.

2.2.6 PG Adjustment
Described below is the platen gap (PG) adjustment.
Purpose:
Adjust the distance between the head surface and the Paper Guide Front Assy
(platen) properly and adjust the parallelism on the 0th column side and on the 80th
columns side to ensure reliable print quality.
Once the Carriage Assy and/or Adjustment Bushes have been removed or
whenever necessary for any other reason, make this adjustment to correct the
deviation of the platen gap.

The thickness gauge to be used must be free from dust and dirt
and from deformation. Be sure to clean it before use.
Take care that the Print Head is not soiled or scratched.
To ensure high accuracy of adjustment, install the Adapters in
the carriage, and move the carriage right and left by pulling the
belt without holding the carriage.
Make this adjustment after installing the Printer Mechanism
and CISS section. (Install the Linear Scale after adjustment.)
Refer to “1.2.2 Disassembly Flowchart” (p.18).
With L800/L801, four stages of PG setting are available by
means of the APG Mechanism. However, make this adjustment
with the mechanism in the minimum PG position (PG-: 1.2

3.1 Overview
This section provides information to maintain the printer in its optimum
condition.
3.1.1 Cleaning
Except for the printhead, there are no other mechanical parts or units that
require periodic cleaning. However, if need arises, clean the component
observing the following instructions.
Instructions for cleaning
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 LD 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.
C A U T I O N
Do not use alcohol for cleaning the transparent parts. Doing so
may cause them to get cloudy.
When wiping paper dust off the LD 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 cloth to remove alcohol traces fully.
3.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the printer
indicates the “Maintenance request error”, take the following actions to clear
the error.
(This error is displayed in EPSON Status Monitor 3 and with LED.)
3.1.2.1 Printhead cleaning
When dot missing or banding appears on images, run the Printhead cleaning
cycle.* The cleaning be activated from the control panel, the printer driver
utility or the Adjustment program.
Note * : This printer has three manual cleaning modes. The appropriate cleaning mode is
automatically selected and performed according to various conditions. The ink
consumption amount for manual cleaning varies depending on the mode.
3.1.2.2 Maintenance request error
Ink is consumed also for cleaning and flashing operations. When the ink is used
for cleaning and flashing operations, the ink is drained to the Waste Ink Pads
via the Pump. The amount of the waste ink is stored as the waste ink counter
into the EEPROM. When the waste ink counter has reached the limit of the
absorbing capability of the Waste Ink Pads, the maintenance request error is
displayed. This printer takes the ink evaporation amount into consideration,
therefore the counter limit differs depending on how often printing is made.
When the maintenance request error appears, replace the Waste ink pads with a
new one and reset the waste ink counter using the Adjustment program. If the
waste ink counter is close to its limit, recommend that the Waste ink pads will
be replaced with new one. This is because the “Maintenance request error” will
may occur after returning the repaired product to the customer.
