2950 Pages Allowed After Toner Collection Unit Lock
This SP displays the number of sheets allowed after the Toner Collection Unit Lock is
detected. After detection, the “Replacement of Toner Recycling Unit will soon be
necessary” message is displayed at the bottom of the operation panel. When this
number reaches 8K, SC487 is issued and the machine stops.
Enter “0” and cycle the machine off/on to reset this symptom.

2961 Developer Initialization (Factory)
DFU
2962 Auto Process Control Execution
Press Start to execute and automatically adjust the following:
1. Drum potential sensor
2. ID sensor
3. Charge grid voltage Vg (by changing Vd)
4. LD power (by changing Vh)
5. VL detection.
Note: Before using this SP, auto process control should be on (SP3-901).
fter changing
the drum, ID sensor, drum potential sensor, LD unit, charge corona wires, or toner
density sensor, this SP should be executed.
2966 Periodical Auto Process Control
Selects whether auto process control is done after 24 hours have elapsed after the last
copy job.
[0~1 / 0/ 1]
0: OFF
1: ON
This setting is required for a customer who keeps the main switch on all day.
2967 Auto Image Density Adjustment
Selects whether auto image density adjustment is done during machine warm up. This
mode is to counter dirty background that occurs when a machine is used in an area that
contains ammonia.
[0~1 / 0/ 1]
0: OFF
1: ON
If Periodical Auto Process Control (SP2-966) is used, this adjustment is done also after
the auto process control is finished.
2968 Toner Density Correction
To prevent the image density dropping during continuous copying after a long interval
(this is caused by a sudden increase of Q/M), VREF is changed by –0.06 V every (100 X
[SP2-974 value + 1]) prints. This correction is applied from when the auto process
control is done, until “(the number of prints set in this SP mode) X (SP2-974 value +1)”
has been made.
