CLD-REV 2 Set reverse rotation: Photo-s Drum stop
Detail To set whether to rotate the CL Drum Motor reversely when the Photosensitive Drum (Y/M/C) is
stopped.
Performing reverse rotation enables to prevent white lines in horizontal scanning direction due to
the backlash of stop, but noise may occur in a low temperature environment.
When 0 is set, reverse rotation is turned OFF if room temperature is lower than 10 deg C, and ON
if the temperature is 10 deg C or higher.
Use Case - When noise occurs at reverse rotation of the drum
- When uneven density/blur at intervals of drum circumference occurs
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Caution Without performing reverse rotation, uneven density/blur at intervals of drum circumference may
occur.
Display/Adj/Set Range 0 to 2
0: OFF when room temperature is lower than 10 deg C, and ON when the temperature is 10 deg
C or higher, 1: ON, 2: OFF
Default Value 0

OHP-PTH 2 Set of ITB clean transp threshold value
Detail To set the number of sheets as the intervals to execute ITB cleaning when feeding transparency.
When a large number of transparencies is fed, surface active agent adheres to the ITB, and
consequently the transfer efficiency is lowered, causing an image failure. Normally, a solid single
Bk-color patch with 80 mm width is formed on the ITB, and surface active agent is removed together
with the toner every time after feeding 10 sheets at paper interval and 5 sheets at last rotation.
As the value is changed by 1, the number of sheets at paper interval and last rotation is changed
by 1 sheet.
When the value is decreased in the case of using transparency to which surface active agent is
more likely to be adhered, image failure can be alleviated.
When the value is increased, downtime and toner consumption can be reduced, but image failure
may occur.
Use Case
When an image failure occurs due to decrease in the transfer efficiency
Adj/Set/Operate Method
Enter the setting value (switch negative/positive by -/+ key) and press OK key.

ITB-CL-L 2 Set toner band length: ITB Clean Blade
Detail To set the length of toner band for preventing flipping of the ITB Cleaning Blade.
Increase the value when noise comes from the ITB due to the flipping. If the length of toner band
gets longer, flipping can be prevented, but toner consumption is increased.
When 0 is set, toner band is not formed.
Use Case - When noise comes from the ITB
- When low productivity or high toner consumption is pointed out by the user
Adj/Set/Operate Method Enter the setting value, and then press OK key.
Caution Do not use this when the machine is operating correctly.
