SERVICE PROGRAM MODE TABLES
Adjusts the voltage applied to the grid
plate during copying when auto process
control is off.
[-600~-1300 / -900 / 10 V]
Normally, there is no need to adjust this.
However, if there is an ID or TD sensor
problem, the machine goes into fixed
toner supply mode. After replacing the
drum or charge corona wire, reset this
value to the default.
Adjusts the voltage applied to the grid
plate when making the ID sensor pattern,
when auto process control is switched
off.
[-600~-1300 / -770 / 10 V]
Normally, there is no need to adjust this.
If the user wants high-density copies, the
sensor pattern must be lighter, so this
voltage must be a higher negative
voltage.
Adjusts the voltage applied to the grid
plate during copying when auto process
control is switched on.
[-600~-1300 / -1000 / 10 V]
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 Transparency mode is
selected.
[-600~-1300 / -770 / 10 V]
Use this if there is a copy quality problem
when making copies on Transparencies.
Normally there is no need to adjust this
SP.
Adjusts the current applied to the charge
corona wire except in Photo mode.
[-1000~-2800 / -1400 / 10 uA]
corona wire for Photo mode.
[-1000~-2800 / -1600 / 10 uA]
Adjusts the target VD voltage for Process
Control Initial Setting.
[-700~-1000 / -800 / 5 V]
Adjusts the voltage applied to the grid
plate during copying when auto process
control is switched off and the machine is
in the low speed mode.
[-600~-1300 / -850/ 10 V]
