Function/[Setting]
Adjusts the voltage applied to the grid plate
during copying when auto process control is
off.
[–600~–1300/–900/10V Steps]
After replacing the charge corona wire or the
drum, reset to the factory default setting.
Adjusts the voltage applied to the grid plate
when the ID sensor pattern is created.
[–600~–1300/–800/10V]]
Adjusts the total current applied to the charge
corona wire. DFU
[–600~–1300/–1300/10µA]
Adjusts the voltage applied to the grid plate
during copying when auto process control is
on.
[–600~–1300/–900/10µA]
This voltage changes every time auto process
control starts up (every time the machine is
switched on).
Adjusts the voltage applied to the grid plate
when OHP mode is selected.
[–600~–1300/–700/10V]
Use this if there is a copy quality problem
when making OHP's.
Adjusts the voltage applied to the grid plate
when Photo mode is selected. DFU
[–1400~ –1600/–1600/10 µA]
These settings adjust the erase margin for the
leading, trailing, left, and right edges.
