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;

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.

2.1 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.
If the EEPROM data cannot be read out from the old Main Board using the Adjustment
Program when replacing the Main Board is required, the Waste Ink Pad and Lower
Paper Guide Ink Pad Tray must be replaced with the Main Board at the same time.
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.
• “O” indicates that the adjustment must be carried out.
• “---” indicates that the adjustment is not required.
• The “Mechanism Adjustment” should be performed just after reinstalling or
reassembling the part or unit. (See “ Table2-1 Required Adjustment List (Mechanism
Adjustment) (p34)”)
• The “Adjustments using the Adjustment Program” need to be performed after
reassembling the printer completely. (See “ Table2-2 Required Adjustment List
(Adjustment Program) (p35)”)
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.

This section describes PF Timing Belt tension adjustment.
Tools
Sonic tension gauge
Plastic tweezers
Adjustment procedure
When performing the PF Timing Belt tension measurement, make sure of the following.
Bring the microphone of the sonic tension gauge within 5 mm from the Timing Belt but do
not let it touch the belt.
Flip the Timing Belt as weak as the sonic tension gauge can measure it.
Be careful not to damage the Timing belt when flipping it with the plastic tweezers.
1. Set the following parameters to the sonic tension gauge.
Weight: 001.2 g/m
Width: 005.0 mm
Span: 0048 mm
2. Bring the microphone of the sonic tension gauge close to the upper center of the PF Timing Belt.
3. Press the “MEASURE” button on the sonic tension gauge and flip the timing belt with plastic tweezers.
Figure 2-1. Microphone Position
The standard tension range of the PF Timing Belt Tension Adjustment is as follows:
Standard value: 10.5 2N (8.5 - 12.5N)
4. The adjustment is not necessary if the measured value falls within the standard value.
If not, loosen the screws that secure the PF Motor, and change the position of the PF Motor adjuster part of
the PF Motor attachment location little by little to adjust the belt tension. Repeat Step 3 until the measured
value falls within the standard value.

Adjustment procedure
Before starting PG Adjustment, completely wipe drops of ink around the Print Head.
Remaining drops of ink will stick to the continuity measurement point of the adjustment
gauge, and cause continuity before the continuity measurement point makes contact with
the metal frame around the Print Head, interrupting accurate PG Adjustment.
As the ink in the Print Head may stick fast and damage the Print Head during PG
Adjustment, make the continuity time detected with a tester as short as possible.
(Maximum three minutes.)
Move the CR Unit by moving the timing belt.
Place the printer on a level, warp-free table. PG Adjustment cannot be performed
normally on a warped table.
Make sure that the Ink Supply Unit and the CR Support Plate are secured when

2.2.8.1 Overview of the Colorimetric Calibration
Purpose
Measuring the color of the ink discharge amount information and registering/controlling this information
improves calibration accuracy and ensures consistent color quality.
As color measurement is performed with the fully assembled product, the electrical
characteristics which are unique to each Main/Power Board are also compensated in addition
to the Printhead.
To reduce unit-to-unit and mode-to-mode variations in color.
To improve the accuracy of the Ink Counter.
The Color ID can improve the Ink Counter accuracy, which reduces the running cost of ink.
Colorimetric Calibration Technology
The Principle
The ink discharge amount characteristic of a printer is measured by measuring color difference (L*a*b*) of a
printed chart with a calibrator. Created Color ID information based on the obtained L*a*b* values is stored on the
printer.
When printing, the printer sends the Color ID to the printer driver to compensate the number of ink droplets (dot
generation rate) for each of nine
printers to provide consistent print quality reducing unit-to-unit variation.
Example: Compensation of ink amount ejected from a Printhead (dot generation rate)
• When the standard printer generates ten dots.
If the ink discharge amount is insufficient by 10%, this is compensated by generating 11 dots.
Note"*1":Three different sized droplets (small, medium, large) for each of three waveforms (VSD1, 2, 3)
Head ID
In the conventional color calibration with a Head ID, the printhead characteristics (weight of discharged ink) are
measured and compensated. The following shows the correlation between conventional Head ID adjustment and
Colorimetric Calibration.

different sized droplets of each color. This method allows mass-produced
Table 2-3. The Difference in Calibration Method between Head ID and Colorimetric Calibration
Conventional Head ID adjustment Colorimetric Calibration
In the printhead manufacturing process, ink discharge amount of
each head is actually measured to get individual characteristic
information. The information is stored on the printer as Head ID
to control the printhead.
By printing and measuring a color chart, a variation from the
standard machine is obtained and registered as the correction
value (Color ID) to control the amount of ink droplets.
Before performing Colorimetric Calibration, the conventional Head ID must be pre-
registered. This is because the Head ID contains information to create a waveform to
drive the head, which is also required for the Colorimetric Calibration.
If you do not perform Colorimetric Calibration after performing Head ID adjustment,
the printer will be controlled only by the Head ID, which affects the following.
• Ink Counter
The ink consumption counter table switches from the table for Color ID to the one for
Head ID. This change causes an ink out error to occur 2 to 5 percent earlier than when
using the table for Color ID. This varies depending on the print mode (dot type).
• Color quality
Color quality will be at the same level as that of printers adjusted by the conventional
Head ID, and the same color quality as mass-produced printers cannot be maintained.

Supplement: Regarding remaining ink amount
When the Ink Counter detects ink out, a certain amount (safety margin) of ink is still remaining in the
cartridge to prevent the printhead from damages caused by printing without ink. This safety margin is
important especially for a printer that discharges larger amount of ink.

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.
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 Lubrication
The type and amount of the grease used to lubricate the printer parts are determined based on the results of the
