Classification:
Symptom
The image is not completely transferred to the paper, generating non-printed white
areas that appear on the trailing edge of the 2nd side when printing duplex on A3/DLT.
The symptom occurs on approximately the first 30 printouts when running the machine
after a long break while the internal temperature is still low.
In addition, the symptom could also occur after recovering from a jam, if the machine
is run in a low temp/humidity environment.
Cause
Condensation builds up on the fusing exit guide plates.
Solution
Do steps 1 to 4 and check the results. If the problem persists, do step 5.
1. Set the timer so that the machine power is turned on 30 min before printing.
System Settings > Timer Settings
2. Extend the reload duration of the fusing motor to 500 sec (default 280 sec).
SP1-101-007 (Reload Permit Setting: Rotation Time: Cold)
3. Change the interval for the shift from reload temperature to standby temperature
to 990 sec (default 300 sec).
SP1-121-001 (Switch: Rotation Start/Stop: Time: After Reload)
4. Set the timer so that the machine waits for 240 min (default 60 min) before it
enters the standby mode.
System Settings > Timer Settings > Auto Power Off Timer
5. Enable the anti-condensation function. Select "1" (default 0).
