Select ProCon Select Process Control Method
The settings of these SP codes modify the operation of the automatic process control
self-check. Automatic process control is done at these times:
• When the machine is turned ON
• At the end of the job, if the number of pages since the previous process contro,
exceeds the value of SP 3551
• Before ACC adjustment
• When the developer is initialized with SP3811.
For more about process control, see "Process Control" in Section "6.11" of the service
manual.
001
Potential Control
[0~1/1] 0:Auto, 1:Fixed
When the machine starts (with the front door closed), the process control self-check
begins using as referernce bias voltages set with the Group 3 SP codes. The
referenced voltages are different, depending on whether "Auto" or "Fixed" is set:
Referenced SPs with "Auto" Selected
SP3575 000~008 Dev DC Control
SP3576 000~008 Chrg DC Control
SP3577 000~008 Chrg AC Control
SP3581 000~008 LD Power Control
SP3551 001, 002 Procon Int
SP3554 001 Init ProCon Set
SP3801 001 DevSetup Execute
SP3811 001~006 DevSetup Execute
Reference SPs with "Fixed" Selected
SP2201 001~009 Set DC Charge
SP2202 001~009 Set AC Charge
SP2211 001~009 Set LD Power
SP2212 001~009 Set Dev DC
002
Potential Ctrl Switches process control gamma correction OFF (0) and
ON (1).
[0~1/1]
003
Density Adj Mode Sets the execution timing of toner density adjustment with
the automatic process control self-check.
[0~2/1]
0: Do not execute, 1: 1st Power On, 2:1st Power On & Job
End
004
ACC Before ProCon Determines whether process control is executed before a
gradation test pattern is printed using the operation panel
with:
[User Tools]> Maintenance> Auto Color Calibration
[0~2/2]
0:Do not execute
1:Execute Potential Control
2:Execute Potential Control and Toner Density Adjustment
005
Dnstiy Adj Times Sets the upper limit of the loop wherein density is adjusted
during process control. Default: 10
