Troubleshooting
Step Check
Check of transparency setting
1
Does the transparency in use match the
NVRAM setting (which type of transparency
(with or without white margin) is enabled or
disabled.)
Does the error recur when a test print is
2
made?
Check of dirt and foreign bodies on surface
3
of SENSOR OHP
Open COVER-P/H.
Are there any dirt or foreign bodies on the
SENSOR surface?
Does the error recur when a test print is
4
made?
Operation check of SENSOR OHP
5
The voltage of P408-8 ↔ P408-7 on PWBA
MCU is 5 VDC when white paper is brought to
the sensor sensing area (transparency must not
be used), and becomes 0 VDC when paper is
removed?
