procedures preceded by DANGER Headings.
Signals a precaution which, if ignored, could result in damage to equipment.
DANGER
1. ALWAYS DISCONNECT THE PRODUCT FROM THE POWER SOURCE AND PERIPHERAL DEVICES PERFORMING ANY MAINTENANCE OR
REPAIR PROCEDURES.
2. NOWORK SHOULD BE PERFORMED ON THE UNIT BY PERSONS UNFAMILIER WITH BASIC SAFETY MEASURES AS DICTATED FOR ALL
ELECTRONICS TECHNICIANS IN THEIR LINE OF WORK.
3. WHEN PERFORMING TESTING AS DICTATED WITHIN THIS MANUAL, DO NOT CONNECT THE UNIT TO A POWER SOURCE UNTIL
INSTRUCTED TO DO SO. W HEN THE POWER SUPPLY CABLE MUST BE CONNECTED, USE EXTREME CAUTION IN WORKING ON POW ER
SUPPLY AND OTHER ELECTRONIC COMPONENTS.
WARNING
1. REPAIRS ON EPSON PRODUCT SHOULD BE PERFORMED ONLY BY AN EPSON CERTIFIED REPAIR TECHNICIAN.
2. MAKE CERTAIN THAT THE SOURCE VOLTAGES IS THE SAME AS THE RATED VOLTAGE, LI STED ON T HE SERIAL NUMBER/RATING PLAT E. IF
THE EPSON PRODUCT HAS A PRIMARY AC RATING DIFFERENT FROM AVAILABLE POW ER SOURCE, DO NOT CONNECT IT TO THE POW ER
SOURCE.
3. ALWAYS VERIFY THAT T HE EPSO N PRODUCT HAS BEEN DI SCONNECT ED FRO M THE POWER SOURCE BEFORE REMOVING OR REPLACING
PRINTED CIRCUIT BOARDS AND/OR INDIVIDUAL CHIPS.
4. IN ORDER TO PROTECT SENSITIVE MICROPROCESSORS AND CIRCUITRY, USE STATIC DISCHARGE EQUIPMENT, SUCH AS ANTI-STATIC
WRIST STRAPS, WHEN ACCESSING INTERNAL COMPONENTS.

1.3.2.1 Switches
On line switch:Switches the printer between on line and off line
status.
Form feed switch: When the printer is off line and data remains in the
printer’s memory, prints out the data and clears the
buffer. If used in combination with the Alt button, a
status sheet is printed.
Continuous switch:Enables the printer to resume printing after certain
maintenance-required conditions or errors have been
cleared. If used in combination with the Alt button, the
printer is reset.
Alternate switch:Use this button in combination with the Continue
button in order to stop printing and reset (Warm boot).
In the reset condition, if both Alt switch and Continue
switch are pressed more than 5 seconds, the printer
goes to “Reset All” condition.
1.3.2.2 Lights
On Line LED(green):Displays a non-flashing light when the printer
is on line, indicating the printer can receive
print data. When the printer is off line, this light
is off. The light flashes as the system switches
between on-line and off-line status.
Form Feed LED(yellow): Comes on when data is received and stored in
the printer’s buffer prior to printing. Flashing
indicates the printer is processing data. When
no data remains in the printer buffer(the
section of memory reserved for receiving
data), this light is off.
Continue LED(red):Flashes when an error is detected or a
maintenance procedure must be performed.
Paper LED(yellow):Displays a non-flashing light when a general
paper error, or “Printer Open” error has
occurred.
Toner LED(yellow):Displays a non-flashing light when it is time to
change the developer cartridge (toner).
Flashes to indicate the toner is low.

occurred. Flashes when the resolution is
reduced from 600 to 300 dpi, because of lack
of memory size.
This printer has no LCD display in the control panel, so it is not possible to
make function settings from the control panel, excluding toner left quantity
reset and OPC drum life reset by the special operation and status sheet.
Refer to Chapter 3 for error conditions.
Function settings can be performed using “RCP”(remote control panel).
In the Table below, note that the bold and italic value in the “Value” column
CAUTION
This printer has EEPROM to maintain the function
setting. Data-writing to EEPROM can not be
guaranteed, if the power is turned off during
writing. Therefore, sometimes service error call
occurs or the panel setting returns to the initial
setting by all reset or at the next power on. In
order to prevent this, do not turn off the printer at
the following conditions, since data-writing to
EEPROM is performed.

1.3.4.2 Up-dating ROM Program
Since the ROM programs, which were produced during the initial massproduction, are using Flash-ROM, they can be up-dated through the parallel
interface from the host computer, when it becomes necessary to up-date.
Procedure for up-dating
1. Connect the printer and host computer by parallel interface cable.
2. Turn the power of the printer on, while pressing On-line, Form Feed and
Continue switches.
3. Stop pressing switches after Paper, Toner and Memory lights turn on.
Continue light and From Feed light turns off 3 seconds after other lights turn
on with flashing On-line light. The printer is ready to receive the program
data from the host computer.
4. Transfer the program data by COPY command of DOS from the host
computer, as it is shown below.
>COPY_/B_File Name_LPT1 press Return key.
Note)
”_” above means to take one space.
CHECK POINT
9
The printer indicates that old program is being erased, turning the Toner,
Memory and Form Feed lights on and blinking the on-line light.
Then, the printer indicates that new program is being written, turning the
Memory and Form Feed lights on and blinking On-line light.
5. On-line light blinks and other lights turns off after up-date process is
completed normally.
6. Press On-line switch and re-boot the printer.
Printer should be receiving condition before the
data is sent from the host computer.
CAUTION
If you fail to up-date the program ROM correctly,
Service Req. Error appears and the printer will not
be able to start.
Solution when error occurs.
If up-dating RON fails, error is indicated and goes to Check SUM error
(service req. error) without appropriate operations.
Write Error
Because of defective device of Flash-ROM or defective confection
with DIMM slot, Paper, Continue and Form Feed lights turn on while
writing or erasing program , then On-line light blinks and light error is
indicated. Operation is canceled by pressing Alt switch. In this case,
old program still remains and transferred data is red but abandoned.
Up-date is proceeded by pressing On-line switch, but the printer does
not operate well.
Data Error
Data error is indicated by turning Toner, Continue and Form Feed
lights on and blinking On-line light.
Operation is canceled by pressing Alt switch. In this case, old
program still remains and transferred data is red but abandoned.
Up-date is proceeded by pressing On-line switch, but the printer does
not operate well.
Address Error
This error occurs when writing address to program ROM is done out
of range. Address error is indicated by turning Toner, Continue and
Form Feed lights on and blinking On-line light. Operation is canceled
by pressing Alt switch. In this case, old program still remains and
transferred data is red but abandoned. Up-date is proceeded by
pressing On-line switch, but the printer does not operate well.
Check SUM Error of Program ROM
When up-dating ROM fails, Check SUM error appears. Memory and
Continue lights turn on and On-line light blinks to indicate Check SUM
error. Press On-line switch and re-boot the printer.
