Replace drum cartridge.
B: Sharp white band appears at the single color (foreign material on the laser path)
[Probable cause] Dust, toner and so son attaches to the light path for the image wiring and
locks the laser beam, causing white band to appear.
[Solution]
Clean the soil and dust which block the light path with the Hydrowipe.
(Specifically, the lower part of the developing casing.)
C-a: White line appears at the single color (intermediate transfer belt filming)
[Probable cause] Filming of intermediate transfer belt sometimes occurs and the belt
resistance changes. As the result, poor transfer occurs and white band appears.
[Solution]
Adjustment => [03 Execute Adjustment] => Perform [Belt refresh mode]
Only one time as the maximum.
Toner consumption per one time adjustment is: C and M toner A3 solid 5 sheets equivalent
Filming tends to occur with the frequent print of low coverage or B5 or 5”1/2×8”1/2 or less size.
CAUTION:
Do not perform belt refresh or toner refresh more than specified maximum times.
Otherwise, toner cleaning failure and other problem may occurs.
During the BT developing process, belt refresh or toner refresh is rarely used and BT
presumed refresh mode is basically not needed.
