3531 ProCon Target
This SP sets the value for the maximum coverage to be achieved by the process
control self-check. Process control then analyzes the readings of the 10-grade
pattern, calculates the potentials required for develoment gamma and Vk (starting
voltage), and then determines the drum charge levels, development biases, and LD
power levels necessary to achieve the target coverage.
Note
This SP can be used to darken printed images.
After this SP is changed, process control must be executed manually with
SP3820.

3551 ProCon Int
This SP sets timing of the process control self-check for job end. Normally, process
control executes automatically after 250 jobs. The process control self-check never
interrupts a job to execute, even if it is time for the next self-check.

3554 Init ProCon Set
001 Sets fusing temperature threshold for execution of the process control self-check
execution after a cold start. If the machine is switched OFF and then switched ON
again, the automatic process control self-check will not execute if the fusing
temperature remains above 100
Note: Use SP3554 001 to display the results of the process control self-check.
[0~150/1 deg C]
3561 Dev :Disp/Set
Displays the value of development gamma, an indicator of development capacity. In
order for the machine to determine the development potential to obtain the target
coverage. During processing control the 10-grade patterns are created first on the
drums and then on the ITB. The potential sensors read the development potential,
and the ID sensors read the amount of coverage on the ITB.
Plotting the development potential on the X axis against coverage on the Y-axis
results in the development gamma curve. For more, see "Process Control" in Section
"6.11 Details".
The normal range for development gamma is greater than 0.3 and less than 6.0.
