Function
After the "Start" key is pressed, forced V
detection is done.
For when to use this SP mode, see "Practical
SP Mode Use Table".
This resets the following data regarding the
OPC drum:
1. V correction level
R
2. V correction level
L
3. OPC counter
4. T/H correction level
This SP mode must be used only when a
new drum is installed. Refer to "Practical SP
Mode Use Table" for the exact timing for using
this SP mode.
Selects whether auto process control mode is
on or off.
If the auto process control mode is switched
off, V correction, V correction, and the
R L
1000-copy process control cycle will not be
performed.
This SP mode can be used to help determine
whether a copy quality problem is caused by
process control or by the machine itself.
Performs a free run with the exposure lamp off.
Start the free run by pressing the "Start" key
and stop it by pressing the "Clear/Stop" key.
Be sure to perform this mode without a
development unit, or too much toner will
be consumed from the developer, causing
low image density.
Performs the 1000-copy process control
cycles forcibly.

ADS
This mode starts after the "Start" key is
pressed.
Adjusts the exposure lamp voltage
(0.5 V per step [Range: 50.0 V to 75.0 V])
For 115 V machines, the actual applied
voltage = displayed value x 1.1412.
After doing this SP mode, ADS initial
setting (SP4-201) and forced V
(SP3-105) must also be done.
See "Replacement and Adjustment - Copy
Quality Adjustments" for how to adjust.
