4.8.5 Low voltage power supply PCB ASSY failure
4.9 Other Problems
4.9.1 The printer is not turned on, or the LED indication does not appear.
4.9.2 Fuser fan does not rotate.
User Check
• Turn the power off and on.
Step Cause Remedy
1
Harness connection failure of low
voltage power supply PCB ASSY
Check the harness connection of the low
voltage power supply PCB ASSY, and
reconnect it.
2
Low voltage power supply PCB
failure
Replace the low voltage power supply
PCB ASSY. Then, reset the irregular
power supply detection counter following
the procedure described in "3.1 Reset of
Irregular Power Supply Detection
Counter" in Chapter 4.
3 Main PCB failure Replace the main PCB ASSY.
CAUTION :
• The irregular power supply detection error (After blinking the Toner/Drum/Error/Ready
LED, the Toner/Drum/Error LED light up by pressing the [Go] button once. ) occurs
when there is a large distortion in the power supply voltage supplied to the printer.
In this case, if the same power supply is used, the same error may occur even when
the low voltage power supply PCB ASSY is replaced. Ask the user to review the
installation environment.
User Check
• Replace the AC power cord.
Step Cause Remedy
