2. “EEPROM ERROR” is displayed.
Possible cause Point to check Solution
EEPROM is not installed
on the MAIN PC board.
“EEPROM ERROR” is displayed when the
EEPROM is not installed.
The EEPROM contains the parameters
required for various operations. Without
EEPROM, the parameters cannot be
found, resulting in an error.
Install the EEPROM properly.
EEPROM is installed in a
wrong orientation.
The EEPROM must be installed in the
correct orientation, as indicated by the silk
screen print on the MAIN PC board or the
connector.
Install the EEPROM in the correct
orientation.
Or, the EEPROM may be damaged.
Replace it with a new one.
EEPROM used for other
model is installed.
Even if the same type of EEPROM is
used, an EEPROM that was used for other
model may cause a malfunction. This is
because different data has been written.
Install an EEPROM for this printer.
Or, replace it with a new one.
3. “100BASE LAN INITIALIZING…” is displayed and does not disappear.
Possible cause Check point Solution
It takes time for
initializing LAN
communication.
When the socket port is set to ON in the
system mode (IP Address setting), LAN
communication is enabled. In that case,
“100BASE LAN INITIALIZING…” may be
displayed for about 20 seconds during
connection.
Wait for a while.
If “ON LINE” is not displayed in a few
minutes, the MAIN PC board may be
faulty.
4. “HEAD OPEN” is displayed.
Possible cause Check point Solution
The top cover is not
closed completely.
When the top cover open sensors do not
detect the hooks of the top cover, “HEAD
OPEN” is displayed. As the sensor is
mounted on either side of the printer, both
top cover hooks should be detected.
Close the top cover completely.
If the message does not disappear even
if the top cover is closed, the printer
could have the following failure:
(1) The top cover open sensors are not
properly attached, or sensor
harnesses are not inserted
completely.
(2) The top cover’s hook
(3) Top cover open sensor, sensor
harness, or MAIN PC board is faulty.
5. Some printers show “ON LINE” and others show “IN LINE”.
Possible cause Check point Solution
Destination setting is
incorrect.
The message for Japan model is “IN
LINE”, and that for other models is “ON
LINE”.
Perform a printer parameter clear after
choosing “QM TYPE”.
6. Unusual message appears on the LCD at a power on, or it takes time to start.
Possible cause Check point Solution
It takes time for an initial
data processing.
When the printer is turn on for the first
time, initial data is written on the EEPROM
and Flash ROM. Sometimes status
message may be displayed.
DO NOT TURN OFF THE POWER while
the initial data is being written.
When the processing is finished, “ON
LINE” is displayed.
Wait for a while.
If “ON LINE” is not displayed in a few
minutes, the MAIN PC board may be
faulty.
