Roller Cleaning
The paper transfer roller is cleaned at the following times:
•
After the user clears a paper jam
•
After the user closes the front cover
•
Just after the main power has been switched on
After paper passes the paper transfer roller, the paper transfer solenoid releases
the paper transfer roller from the image transfer belt.
Then, a certain time after the trailing edge of the paper passes the registration
sensor, the following steps occur:
1) The paper transfer solenoid turns on again, and the paper transfer roller
contacts the image transfer belt.
2) A negative charge is applied to remove toner stuck to the paper transfer
roller.
3) Positive and negative charge is applied alternately to remove any toner that
is still stuck to the paper transfer roller.
Toner removed from the paper transfer roller goes back to the image transfer belt,
where it is removed by the image transfer belt cleaning unit.
