7.3.7 Belt Lubricant Mechanism
Toner filming on the belt will reduce the efficiency of toner separation from
the belt. A small amount of lubricant is regularly applied to the surface of the
transfer belt [A] to help the cleaning blade easily remove toner from the
transfer belt and to help toner to transfer to the paper.
The lubricant brush [B] distributes lubricant from the lubricant bar [D] to the
transfer belt. Basically, the lubricant brush is away from the transfer belt and
contacts the belt under the control of the lubricant brush solenoid [C]. The
lubricant brush contacts after the following conditions:
•
After the last copy job is completed and more than 50 copies have been
made since the last lubrication.
•
In ARDF mode, every 150 copies, even if it is during a continuous copy
job. The machine temporarily stops the copy job (for about 15 s) until the
lubrication is completed. Then it resumes the rest of the copy job.
