PRECAUTIONS
Precautionary notations throughout the text are categorized relative to 1)Personal injury and 2) damage to equipment.
DANGER
WARNING
The precautionary measures itemized below should always be observed when performing repair/maintenance procedures.
Signals a precaution which, if ignored, could result in serious or fatal personal injury. Great caution should be exercised in
performing 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 UNFAMILIAR 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. WHEN THE POWER SUPPLY CABLE MUST BE CONNECTED, USE EXTREME CAUTION IN WORKING ON
POWER 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, LISTED ON THE SERIAL NUMBER/RATING
PLATE. IF THE EPSON PRODUCT HAS A PRIMARY AC RATING DIFFERENT FROM AVAILABLE POWER SOURCE, DO NOT CONNECT IT
TO THE POWER SOURCE.
3. ALWAYS VERIFY THAT THE EPSON PRODUCT HAS BEEN DISCONNECTED FROM 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 ANTISTATIC WRIST STRAPS, WHEN ACCESSING INTERNAL COMPONENTS.
5. REPLACE MALFUNCTIONING COMPONENTS ONLY WITH THOSE COMPONENTS BY THE MANUFACTURE; INTRODUCTION OF
SECOND-SOURCE ICs OR OTHER NONAPPROVED COMPONENTS MAY DAMAGE THE PRODUCT AND VOID ANY APPLICABLE EPSON
WARRANTY.

When input data buffer is full.
During -INIT signal is at low level or during hardware initialization.
During printer error (see -ERROR signal).
When the parallel interface is not selected.
ERROR signal is at low level when the printer is in one of the following states:
Printer hardware error (fatal error)
Paper-out error
Paper-jam error
Ink-out error
PE signal is at high level during paper-out error.

1.3.4 Prevention of Data Transfer Time-out
Generally, hosts abandon data transfer to peripherals when the peripheral is in
the busy state for dozens of seconds continuously. To prevent this kind of timeout, the printer receives data very slowly, several bytes per minute, even if the
printer is in the busy state. The slowdown starts when the remaining input
buffer becomes several hundreds of bytes, and the printer finally gets into the
busy state continuously when the input buffer is full.
USB and IEEE1284.4 on the parallel interface do not require such function.
1.3.5 Interface Selection
The printer has two built-in interfaces: the USB and parallel interface.
These interfaces are selected automatically.
Automatic Selection
In this automatic interface selection mode, the printer is initialized to the
idle state while scanning which interface receives data when it is powered
on. Then the interface which received data first is selected. When the host
stops data transfer and the printer is in the stand-by state for seconds, the
printer is returned to the idle state. As long as the host sends data or the
printer interface is in the busy state, the selected interface is let as it is.
Automatic Selection
An initial state is compatible interface and starts IEEE1284.4
communication when magic strings (1284.4 synchronous commands) are
received.
On
An initial state is IEEE1284.4 communication and data that received it by
the time it is able to take synchronization by magic string (1284.4
synchronous commands) is discarded.
Off
An initial state is compatible interface and never starts IEEE1284.4
communication even if magic strings (1284.4 synchronous commands) are
received.
Interface State and Interface Selection
When the parallel interface is not selected, the interface gets into the busy
state. When the printer is initialized or returned to the idle state, the parallel
interface gets into the ready state. Note that the interrupt signal such as the
-INIT signal on the parallel interface is not effective while that interface is
not selected.
1.3.6 IEEE1284.4 Protocol
The packet protocol described by IEEE1284.4 standard allows a device to
carry on multiple exchanges or conversations which contain data and/or control
information with another device at the same time across a single point-to-point
link. The protocol is not, however, a device control language. It does provide
basic transport-level flow control and multiplexing services. The multiplexed
logical channels are independent of each other and blocking of one has no
effect on the others. The protocol operates over IEEE1284.

Priority
There are three kinds of initialization methods, and the following explains each
initialization.
1. Power-on Initialization
This printer is initialized when turning the printer power on, or printer
recognized the cold-reset command (remote RS command).
When printer is initialized, the following actions are performed:
(a) Initializes printer mechanism.
(b) Clears input data buffer.
(c) Clears print buffer.
(d) Sets default values.
2. Operator Initialization
This printer is initialized when turning the printer power on again within 10
seconds from last power off, or printer recognized the -INIT signal
(negative pulse) of parallel interface.
When printer is initialized, the following actions are performed:
(a) Cap the printer head.
(b) Eject a paper.
(c) Clears input data buffer.
(d) Clears print buffer.
(e) Sets default values.
3. Software Initialization
The ESC@ command also initialize the printer.
When printer is initialized, the following actions are performed:
(a) Clears print buffer.
(b) Sets default values.

1.4.6 Errors
Ink Out
When the printer runs out most of the ink of any color, it indicates ink-low
and keeps printing. When the printer runs out the whole ink of any color, it
stops printing and indicates ink-out error. User is then requested to install a
new ink-cartridge in this state. An ink-cartridge that has been taken out
once should never be used again. Re-installation of the cartridge not filled
fully upsets the ink level detection and may eventually cause a serious
problem in the print head.
Paper Out
When the printer fails to load a sheet, it goes into a paper out error.
Paper Jam
When the printer fails to eject a sheet, it goes into a paper jam error.
No Ink-Cartridge
When the printer detects that ink-cartridge comes off, it goes into this error
mode.
Maintenance Request
When the total amount of ink wasted through cleanings and flushing
reaches to the limit, printer indicates this error and stops. In such a case,
the absorber in the printer enclosure needs to be replaced with new one by
service personnel.
Fatal Errors
Carriage control error or CG access error.
