10)Transfer belt cleaning blade
This blade removes the residual toner, paper dust or foreign objects on the transfer belt surface. It is
pressed onto the transfer belt unit by its spring. The recovery blade and urethan seal prevent the
removed residual toner or other objects from leaking out of the transfer belt cleaning unit.
11)Used toner auger
This auger transports the residual toner, paper dust or foreign objects scraped off by the transfer belt
cleaning blade to the toner bag.
12)Transfer belt motor (M7)
This two-phase stepping motor drives the drive roller of the transfer belt unit and the used toner
auger.
13)2nd transfer roller
This metal roller, covered with sponge and an NBR tube, is located to face the 2nd transfer facing
roller through the transfer belt. When the registration motor is rotated reversely, the drive from the
registration motor is transmitted to this roller through the cam and arm, and thus this roller contacts
with or releases from the transfer belt.
14)2nd transfer roller position detection sensor (S29)
This photointerrupter detects if the 2nd transfer roller is contacted with or released from the transfer
belt.
15)Paper clinging detection sensor (S27)
This sensor detects thin paper clinging to the transfer belt. When a sheet of thin paper which is not
allowed in the specification is fed, this thin paper may cling to the transfer belt. The clung paper
causes a service call because it cannot be removed in a normal jam releasing process. This sensor
forestalls such case and helps to remove it as a normal paper jam.
