OHP-PTH
Set of ITB clean transp threshold value
Details
To set the number of sheets for ITB cleaning interval to be executed
when feeding transparency.
When a large number of transparencies is fed, surface active agent
adheres to the ITB, and the blade bounds in small motions. As a result,
an image failure occurs.
At last rotation of the job with more than specified number of sheets,
execute ITB cleaning (not executed when 0 is set).
As the value is incremented by 1, the number of sheets for cleaning
interval at last rotation is increased by 1 sheet.
When using the transparency that tends to cause the adherence of
surface active agent, decrease the value so that the image failure can
be alleviated.
When the value is increased, the downtime and the toner consumption
can be reduced; however, image failure may occur.
Use case
When an image failure occurs due to lowering of the transfer efficiency
Adj/set/operate method Enter the setting value, and then press Start key.

alleviated, but downtime and toner consumption are increased.
Toner band width that is formed at ITB cleaning differs depending on
the setting value (1<2<3=4=5).
Use case
When setting the interval to execute ITB cleaning
Adj/set/operate method Enter the setting value, and then press Start key.

DR-CL-L
Set toner band length: Drum Clean Blade
Details
To set the length of toner band for preventing flipping of the Drum
Cleaning Blade.
Increase the value when noise comes from the Photosensitive Drum
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 Photosensitive Drum
• When low productivity or high toner consumption is pointed out by
the user
Adj/set/operate method Enter the setting value, and then press Start key.
Caution
Do not use this when the machine is operating correctly.

DR-CL-T
Set toner band form intvl:Drum Cln Blade
Details
To set the interval to form toner band for preventing flipping of the Drum
Cleaning Blade.
Decrease the value when noise comes from the Photosensitive Drum
due to the flipping. If the interval to form toner band is decreased,
flipping can be prevented, but toner consumption is increased.
Use case
• When noise comes from the Photosensitive Drum
• When low productivity or high toner consumption is pointed out by
the user
Adj/set/operate method Enter the setting value (switch negative/positive by -/+ key) and press
Start key.
Caution
Do not use this when the machine is operating correctly.
