Blank area cased by poor secondary transfer
[Occurrence area]
Secondary Transfer Outer Roller
[Cause]
Since the resistance of a paper changes when the recycled paper having bad surface nature
is used under the high temperature and high humidity environment, the current value of the
Secondary Transfer may be insufficient. As a result, the blank area caused by Secondary
Transfer failure may occur.
[Occurrence condition]
In case that the recycled paper having bad surface nature is used under the high temperature
and high humidity environment.
This phenomenon will be more obvious when a blue solid image is copied.
[Remedy]
Please perform the following steps.
1) Check environmental classification inside the machine.
Indication of inside environmental classification (COPIER > DISPLAY > MISC > ENV-TR)
<Level1>
2) Check the "paper type" when the poor image occurred. (Example: Plain paper 1)
3) Check the "printing surface" which the poor image occurred. (Example: In the case of a first
side)
4) Perform adjustment of secondary transcription ATVC target current (COPIER > ADJUST >
HVTR > XXXX).
F-6-15
Set the setting value of the applicable service mode to "+10" after checking the sub-item
name corresponding to XXXX from the following table. If not improved, please increase the
setting value by +10 each.
(Example: When the paper type is the plain paper 1, environmental classification is 1 and it is
on a first side, COPIER > ADJUST > HVTR > 2TR-N1)
