Prohibited Matters
Never deactivate the safety equipment installed on the product for any reason
whatsoever.
Never modify the safety equipment or replace it with part not approved by
EPSON. Doing so may cause the safety functions to stop working properly, and
may result in fire or injury.
Never modify the product. If you are instructed to do so, however, fully
understand the instruction and perform the modification.
To prevent an electric shock, burn, injury, etc., always turn the
printer off and unplug the power cord before starting maintenance
work. When the power supply cable must be connected to measure
voltage or for any other task, strictly follow the instructions and use
extreme caution in working on electronic components.
Pay particular attention to the high-voltage part indicated with the
symbol on the left.
Do not touch the high temperature parts indicated with the symbol
on the left. Those parts are extremely hot immediately after use. If
you need to replace those parts, leave the printer until it cools.
Connect the printer to an electrical outlet that matches the printer’s
rated voltage and power requirements.
Do not connect any other devices to the electrical outlet supplying
the printer. Doing so can cause overloading of the electrical circuit
and may cause a fire.
Do not use extension cords or power adapters to plug multiple
devices into the same outlet. Power plug and electrical outlet should
be free from dust or foreign objects.
The printer should be properly grounded to prevent electric shock.
The grounding terminal should be one of the followings:
a. One of the electrical outlet
b. One that is grounded by a D-type grounding construction.
(The former third-type grounding construction; grounding
resistance under 100 Ω).
Power cord should not be deformed or damaged. If the cord is
damaged, replace it with a new one dedicated for the product.
Use the specified service parts for repair and maintenance.
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.
After replacing the Fuser Unit or any other parts to which AC
voltage is applied, be sure to check the part is properly installed and
the connecting cables are not caught between metal parts.
Otherwise a fire or an electric shock may occur.
Fuse on the Power Supply Unit must not be replaced under any
circumstances.
Page 8
Before performing repair and maintenance work, read and
understand the documents of the product (e.g. service manual).
Be sure to follow the specified steps and use the prescribed tools
described in the documents.
When disassembling or assembling the product, make sure to wear
gloves to avoid injury from metal parts with sharp edges.
Take care not to drop any screws, washers, or clips inside the
printer body. Should it fall in, do not boot up your printer until the
part has been safely removed.
After reassembling the printer, make sure all the parts and the
screws are put back in place and the cables are not caught between
metal parts.
Do not use vacuum cleaner for home use to clean up spills of
powdered toners. The very fine particles can cause fire/explosion.
Sweep them thoroughly with a broom or wipe them with a cloth
moistened with neutral detergent. If a large amount of toner is
spilled, use a toner vacuum designed specifically to clean toner.
Ozone gas is generated by the printer as a by-product of the
printing process. The amount of gas is too small to be harmful,
however, some users may feel uncomfortable under the following
conditions. It is desirable to advice the users to ventilate the room
when using the printer.
When using the printer for a long period of time in a room with
poor ventilation.
When printing a large amount of documents at a time.
When using multiple printers in the same room.
In order to protect sensitive microprocessors and circuitry, use
static discharge equipment, such as anti-static wrist straps, when
accessing internal components.
Though toner and developer are safe for human body, they may
cause irritation to skin and eyes. If toner gets into your eyes, wash it
away immediately with water. If irritation continues, see a physician.
If toner gets in your mouth, rinse immediately with plenty of water.
If swallowed, induce vomiting and consult a physician.
Do not throw used toner cartridges or toner into the flames.
Do not use thinner or alcohol when cleaning the product as it may
result in discoloration or deformation.

2.2 Technical Explanation of Print Process
2.2.1 Charging
DRUM SECTION
The durable layer of organic photoconductor (OPC) is coated over the aluminum
cylinder base. The OPC tend to reduce its own electrical conductance when exposed to
light. After a cyclic process of charging, exposure, and development, the electrostatic
image is constituted over the OPC layer. Since the OPC is materialized by resin, it is
susceptible to damage caused by sharp edges such as a screwdriver, etc., resulting in a
print quality problem. Also, finger prints can cause deterioration of the OPC layer,
therefore, the drum (in the drum unit) must be handled with care. Substances like water,
alcohol, organic solvent, etc., should be strictly avoided. As with all other OPC drums,
the exposure to a strong light source for a prolonged period can cause a print quality
problem. The limit is approximately 500 lux for less than five minutes. If the drum
(drum unit) remains removed from the printer, it should be stored in a cool, dark place.
Drum cover A
MAIN CHARGER UNIT
As the drum rotates in a “clean (neutral)” state, its photoconductive layer is given a
uniform, positive (+) corona charge dispersed by the main charger wire. Due to highvoltage scorotron charging, the charging wire can get contaminated by oxidization
after a long run. Therefore, the charger wire must be cleaned at a specific interval.
Cleaning the charging wire prevents print quality problems such as black streaks.

2.2.2 Exposure
LASER SCANNER UNIT (LSU)
The charged surface of the drum is then scanned by the laser beam from the laser
scanner unit.
The laser beam (780 nm wavelength) beam is dispersed as the polygon motor revolves
to reflect the laser beam over the drum. Various lenses and mirror are housed in the
laser scanner unit, adjust the diameter of the laser beam, and focalize it at the drum
surface.

2.2.3 Development
The latent image constituted on the drum is developed into a visible image. The
developing roller contains a 3-pole (S-NS) magnet roller and an aluminum cylinder
rotating around the magnet roller. Toner attracts to the magnet sleeve since it is
powdery ink made of black resin bound to iron particles. Developing blade,
magnetized by magnet, is positioned approximately 0.3 mm above the magnet sleeve to
constitute a smooth layer of toner in accordance with the magnet sleeve revolution.
The developing roller is applied with the AC-weighted, positive DC power source.
Toner on the magnet sleeve is given a positive charge. The positively charged toner is
then attracted to the areas of the drum which was exposed to the laser light. (The gap
between the drum and the magnet sleeve is approximately 0.32 mm.) The non-exposed
areas of the drum repel the positively charged toner as these areas maintain the positive
charge.The developing roller is also AC-biased to ensure contrast in yielding by
compensating the toner’s attraction and repelling action during development.

2.2.4 Transfer/Separation
The transfer/separation section consists of the transfer roller, discharger brush and
paper chute guide. A high voltage generated by the HVPS (High Voltage Power
Supply) is applied to the transfer roller for transfer charging. Paper after transfer is
separated from the drum.

2.2.5 Cleaning
After the transferring process, the drum needs to be physically cleaned of toner which
is residual after the development process. The cleaning blade is constantly pressed
against the drum and scrapes the residual toner off to the sweep roller. The waste toner
is collected at the output end of the sweep roller and sent back to the toner container,
into the waste toner reservoir.
After the drum is physically cleaned, it then must be cleaned to the electrically neutral
state. This is necessary to erase any residual positive charge, ready to accept the
uniform charge for the next print process. The residual charge is canceled by exposing
the drum to the light emitted from the eraser lamp (PWB). This lowers the electrical
conductivity of the drum surface making the residual charge on the drum surface
escape to the ground.

2.2.6 Fusing
The toner on the paper is molten and pressed into the paper as it passes between the
heat roller and the press roller in the fuser unit. The heat roller has a heater lamp inside
which continuously turns on and off by the fuser thermistor to maintain the constant
temperature onto the heat roller surface. The heat roller is resin coated by florin to
prevent toner from accumulating on the roller after a long run. Care must be taken
while handling the heat roller not to scratch the roller surface as doing so may result in
print problems. Fuser temperature is optimized to the paper type. The heat roller has
four separators (claws) which are continuously in contact with its surface. These
separators (claws) prevent the paper on which toner has been fused from being wound
around the heat roller causing paper jam. The press roller is made of the heat-resistant
silicon rubber. This roller is used to strongly press the paper towards the heat roller by
means of press springs. The temperature of the heat roller is constantly monitored by
the main board assy. using the fuser thermistor. Should the temperature of the heat
roller exceed the predetermined value, the fuser thermal cutout is activated to
effectively disconnect the heater lamp from power.

2.2.7 Paper exit section
The paper exit section transports the paper which passed the fuser unit towards the top
tray. The paper which passed through the fuser unit turns on the actuator (exit sensor)
in the fuser unit, and is led by the guide comprised of the rear cover, frame and the FD
cover guide, finally reaching the upper FD roller. The paper is delivered to the top tray
by the rotation of the upper FD roller.

3.4.3 Controller-related Service Call Errors
Remedy
When a controller-related error occurs, first check on the initial check items listed
below. If the printer still does not recover, troubleshoot the problem with reference
to the tables given on the following pages. Find the error you face in the tables,
and replace the error-causing parts one by one.
Initial check
Is the printer properly grounded?
Are the connectors properly connected to the controller board?
Is the DIMM properly installed on the controller board?
Does the printer recover by turning the power off and back on several times?
Is there any equipment that causes noise around the printer?
When turning the printer off and on for the above initial check,
wait for several seconds before turning it back on. Do not turn it
back on immediately after power-off.
