Important:
The following symptom is the same as the one announced in RTB RB051007a
(Model U-C1). However, if the development unit is not installed correctly in the field, the
production line solution in RTB RB051007a cannot prevent the symptom. Therefore at
machine installation, make sure to do the check in the “Solution” below.
SYMPTOM
A blank area (
sample 1
) or blank patches (
sample 2
) may appear on the side edges of
the paper.
Note:
Also, because of this problem, the ID sensor pattern on the OPC is blank. If the
machine reads this, it can change the process control conditions.
CAUSE
The gears of the development unit do not engage the mainframe gears correctly.
Note:
This can occur at toner cartridge replacement, when the old toner cartridge is not
pulled out correctly.
Sample 1
Mainframe gears
