Function
Adjusts the voltage applied to the drum charge
roller during copying.
The adjustment factor set with this SP mode is
added to the base voltage.
(30 V per step [Range: Base voltage - 480 V
to Base voltage + 480 V]
Displays the voltage applied to the drum
charge roller.
SP2-002-001: For copying
SP2-002-002: For making V
The first three digits are displayed in the
reduce/enlarge indicator. The actual value is
the displayed value x (–10) V.
Just after the main switch is turned on, the
initial setting voltage is displayed.
After one or more copies, the actual applied
voltage (including the process control
corrections) is displayed.
Adjusts the voltage applied to the drum charge
roller when making V patterns.
SP
The adjustment factor set with this SP mode is
added to the base voltage.
(10 V per step [Range: Base voltage –160 V
to Base voltage + 160 V]
Adjusts the leading and trailing edge erase
margins.
SP2-101-001: Leading edge erase margin
SP2-101-002: Trailing edge erase margin
(0.5 mm per step [range: 0.0 mm to +16.0
mm])
Adjusts the development bias for copying to
make copies lighter or darker in general.
The adjustment factor set with this SP mode is
applied to the base voltage.
(20 V per step [Range: Base voltage –80 V to
Base voltage +80 V])
Adjusts the development bias for manual ID
level 7.
The adjustment factor set with this SP mode is
applied to the base voltage when ID level 7 is
selected.
Adjusts the development bias for making V
patterns
The adjustment factor set with this SP mode is
added to the base voltage.
