2.2.13 LUBRICANT APPLICATION MODE
Lubricant application mode for a new PCU
A new PCU does not have used toner on it. Idle rotation of a new PCU may result
in scratches on the OPC belt, damage to the blade, and insufficient cleaning due to
friction between the cleaning blade and the OPC belt or transfer belt.
To prevent this friction, the above lubricant mode is executed.
The first step of this process puts toner on the OPC belt to lubricate it. The transfer
belt is also lubricated at this time. However, the transfer belt requires more
lubrication than the OPC belt. Therefore, step 2 is done to lubricate the transfer belt
without applying toner to the OPC.
This process takes place when the machine detects that a new PCU has been
installed.
