System SP Tables-2
Transfer Roller Cleaning
2996
These SP codes determine how the transfer roller is cleaned.
0:OFF 1:ON
Selects whether the transfer roller is cleaned. Transfer roller cleaning is
necessary only when black spots occur in the image areas of copies. This
can occur when bad environmental conditions increase the toner density.
1
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 regardless of
the SP2996 001 setting.
[0 = No / 1 = Yes]
Interval
This SP sets the page interval for transfer roller cleaning when SP2996 001
is set to "1" (Yes). Increase this setting only when absolutely necessary. A
higher setting increases wear on the PCU.
2
[0to100/50/1 sheets]
Note: This SP does not execute for the first copy after power on or when the
machine returns from the energy save or auto off mode.
This SP setting does cannot correct poor copies if there is a problem with the
TD sensor.
