The laser temperature control cannot
be performed, because the ambient
temperature is too low(high).
Adjust the ambient temp. between 15
to 30 °C. (Laser temp. adjustment will
be started when the ambient temp.
exceeds 5 °C.)
After the initialization, the ambient
temperature has been outside the
specified range for more than the
specified period.
(Causes of the error message)
1. The current temperature is above
(or below) the specified range.
2. Poorly connected or broken
harness between HS760 on the
THA23 circuit board and CTL15 on
the CTL23 circuit board
3. Faulty thermohygrometer (HS760)
4. Faulty LDD23 circuit board
1. On Menu 0524 “Printer
Temperature Display”, measure
the internal temperature, and
adjust it (using an air conditioner)
to within 5 to 45 °C.
2. Connect the connector, or repair or
replace the harness.
3. Replace HS760.
4. Replace the LDD23 circuit board.

Anti-dust filter of laser unit is about to
its lifetime.
Prepare a new anti-dust filter. No
problem for the moment, but consult
your technical representative.
It’s time to change anti-dust filter.
Replace the filter.

Anti-dust filter of laser unit is about to
its pariodic replacing time.
Consult your technical representative.
It’s time to change anti-dust filter.
(Causes of the error message)
1. Filter has not been replaced.
1. Replace the filter.

the internal temperature, and
adjust it (using an air conditioner)
to within 5 to 45 °C.
2. Connect the connector, or repair or
replace the harness.
3. Replace HS760.
4. Replace the LDD23 circuit board.

occurred.
Shut down scanner with emergency
stop button and restart it. If problems
persist, consult your technical
representative.
Abnormal temperature of AOM driver
is detected.
(Causes of the error message)
1. Faulty temperature control circuit
on the AOM driver
1. Replace the AOM driver.
E-2544
An error detected by R laser (R-LD)
sensor.
Shut down scanner with emergency
stop button and restart it. If problems
persist, consult your technical
representative.

(Causes of the error message)
1. Faulty LDD23 circuit board
2. Faulty laser thermistor
1. Replace the LDD23 circuit board.
2. Replace the laser optical unit.
E-2545
An error detected by G laser(G-SHG)
sensor.
Shut down scanner with emergency
stop button and restart it. If problems
persist, consult your technical
representative.
Laser thermistor detected.
(Causes of the error message)
