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 patch is
formed on the ITB and surface active agent is removed together with the toner at paper interval
for every 30 sheets and at last rotation for every 22 sheets.
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 1) Enter the setting value (switch negative/positive by -/+ key) and press OK key.
2) Turn OFF/ON the main power switch.

ITBB-TMG 2 Set of ITB toner band formation interval
Detail To set the conditions to form toner band to reduce friction between the ITB and the ITB Cleaning
Blade.
Environment: In high/all environments
Paper interval: Every 30/60/100 sheets
At last rotation: Every 30/60/100 sheets
Band length: 20/100 mm
As the interval is shorter and the band length is longer, the lubricating effect is high, but downtime
and toner consumption are increased.
Use Case When noise occurs due to the ITB Cleaning Blade
Adj/Set/Operate Method 1) Enter the setting value, and then press OK key.
2) Turn OFF/ON the main power switch.
Display/Adj/Set Range 0 to 7
0: Depending on the environment (temperature and humidity)
1: In a high temperature environment, at paper interval for every 60 sheets, at last rotation for every
60 sheets, 20 mm in band length
2: In a high temperature environment, at paper interval for every 30 sheets, at last rotation for every
30 sheets, 20 mm in band length
3: In all environments, at paper interval for every 60 sheets, at last rotation for every 60 sheets, 20
mm in band length
4: In all environments, at paper interval for every 30 sheets, at last rotation for every 30 sheets, 20
mm in band length
5: In all environments, at paper interval for every 100 sheets, at last rotation for every 100 sheets,
100 mm in band length
6: In all environments, at paper interval for every 60 sheets, at last rotation for every 60 sheets,
100 mm in band length
7: In all environments, at paper interval for every 30 sheets, at last rotation for every 30 sheets,
100 mm in band length
