Isolating faulty FAN
2
Does the FAN REAR rotate when printing 1 sheet?
Check FAN REAR
Does FAN REAR function normally?
3
Using FAN REAR diagnostic tool, check by Diagnostic
Output Test.
Check LVPS STD for signal
4 Print 1 sheet.

Check LVPS STD for signal
5 Print 1 sheet.
Is P/J165-6PIN <=> P/J165-2PIN 0VDC?
Check PWBA HNB DRV for signal
6 Print 1 sheet.
Is P/J61-3PIN <=> P/J61-7PIN 0VDC?
Check PWBA HNB DRV for signal
7 Print 1 sheet.
Is P/J42-12PIN <=> P/J42-14PIN 0VDC?
Check PWBA HNB MCU for signal
8 Print 1 sheet.
Is P/J12-19PIN <=> P/J12-17PIN 0VDC?
Check FAN REAR
9 Check if an error occurs though the Fan Rear was replaced
with a new one.
Check LVPS STD for signal
10 Print 1 sheet.
