The items in
bold italics
were corrected or added.
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).

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).
