(2) Image is too light.
Print example Cause of trouble
1. The paper absorbs moisture.
2. The contact pressure at the secondary trasnfer roller and the intermediate
transfer belt is too low.
3. The voltage applied to the secondary transfer current is incorrect.
Defective part Check description Corrective Action
1
Paper 1. Check if the paper has
moisture absorbed.
2. Check the humidity at the
place the paper has been
stored.
1. If the paper is damp, replace. Choose a dry
place to store paper.
2. If necessary, install a cassette heater.
2
Conveying unit Check if the right side conveying
unit is closed.
If the conveying unit has not been closed,
check how the conveying guide is locked and
open the conveying guide once, then close.
3
Secondary transfer
roller
Check the position of the sec-
ondary transfer roller during
printing.
Position the pressure cam correctly if the
secondary transnfer roller is off-set.
4
High-voltage
PWB2
Check if the connecting termi-
nals between the high-voltage
PWB2 and the conveying unit
are not dirty nor deformed.
1. If the connecting terminals are dirty, clean.
2. If the connecting terminals are deformed,
correct for a proper conduction.
5
U106 the second-
ary transfer vol-
atage setting
Check the secondary transfer
volatage by U106.
If the value of the secondary transfer voltage
by U106 is not its default, reset it to the default.
