Function
Clears the toner end condition.
Select "1" then press the 7 key to clear the
toner end condition without adding new
toner.
If this is "1", the following are cleared.
• Toner end indicator (goes out)
• Toner near-end counter
• Toner near-end level
When making a lot of copies after changing
this setting to "1", the carrier may be
attracted to the drum when the toner runs
out, which may damage the drum.
Adjusts the upper limit for Vref.
When there is dirty background on the copy,
change this value to around 3.1 V.
Adjusts the lower limit for Vref.
Selects the number of copies that can be
made after a TD sensor error has been
detected. When the machine copies this
amount, an SC condition will occur.
If the optional fax unit is installed, the SC
condition occurs immediately regardless of
the number of prints (this is because the
sender of the fax cannot check the image
quality of the printout).
If the machine starts warming-up after this
time has passed since entering night mode
(for example, to print an incoming fax), the
machine makes an ID sensor pattern.
If this value is greater, there is a greater
chance that background will become dirty.
Selects whether the transfer roller is cleaned
before each copy job.
Set this to '1' when dirty background
appears on the reverse side of the first page
of a copy job. However, the first copy time
will be longer.
If this SP is at 0, the transfer roller is never
cleaned.
See 'Detailed Section Descriptions –
Transfer Roller Cleaning" for more details.
