operation
Specifies the duration of lubrication during reverse
doctor roller rotation.

Job End Interruption 940
1 Job End Interruption
The OPC belt is lubricated after the end of every job
(SP2–941–1). This SP determines whether the
lubrication is interrupted when a job arrives at the printer.
[0 ∼ 1 / 0 / 1 /step]
• 0: Interrupted
•
1: Not interrupted
Image Area Rate
1 M
Specifies the minimum image area (expressed as a
percentage of an A4 page) required to maintain optimum
development unit condition (☛ Toner Revitalization:
SP3–971).
[0 ~ 10.0 / 2.0 / 0.1 %/step]
After 20 sheets over a number of small jobs (or after 50
sheets in one job), if the developed area is less than the
value of this SP mode, toner is transferred to the image
transfer belt and cleaned off. This is performed during
the doctor roller reverse rotation.
2 C
[0 ~ 10.0 / 2.0 / 0.1 %/step]

Toner Revitalization 971
1 Toner Revitalization Enables/disables the toner revitalization.
[0 ~ 1 / 0/ 1 /step]
• 0: Disables
• 1: Enables
Continuous printing with a relatively low coverage ratio
(CMYK less than 5% each) tends to reduce the charge
potential of the toner, because the toner remains in the
hopper for a long time. This can lead to spots on the
copy. Toner revitalization removes this defective toner
periodically.
1C Idling 980
1 1C Idling Enables/disables 1-color idling after paper transfer.
[0 ~ 1 / 0 / 1 /step]
• 0: Disables
• 1: Enables
Set this to 1 if the user complains about diagonal lines in
solid areas of prints that only use one toner color (M, C,
or Y).
