The main motor turns the OPC belt in reverse for 500ms
at the end of every job, to remove unwanted particles
between the OPC belt and OPC cleaning blade.
However, it is not necessary to do this often. In addition,
if the frequency of OPC belt reverse rotation is reduced,
the cleaning blade operates better.
This SP adjusts the counter for the OPC belt reverse
rotation, and is incremented as follows:
LT/A4 LEF or shorter: 1, Longer than LT/A4 LEF: 2.
When this SP reaches its set maximum, reverse rotation
is done for 500ms at job end.
OPC Lubricant Mode 940
1 OPC Lubricant Mode Executes a forced OPC lubrication to reduce the friction
on the OPC belt.
DFU
The OPC belt and the lubricant brush operate for 2
minutes.

When high coverage images are continuously printed,
cleaning of the OPC may not be enough. To correct this,
OPC lubrication is carried out during printing

OPC lubrication is executed under the following
conditions.
•
After the previous OPC lubrication, the number of
output pages reaches the value specified with SP2-
944-4.

The average coverage of the outputs after the
previous OPC lubrication exceeds standard average
coverage condition
