• Developer Flow
1. Toner is supplied from the Hopper.
2. Toner is fed to the lower conveying coil.
3. Toner is fed on to the rear of the unit, while being mixed with developer and triboelectri-
cally charged.
4. The ATDC Sensor installed on the underside of the Developing Unit detects toner-to-
carrier ratio during this time.
5. The developer fed to the rear of the Developing Unit is conveyed further to the upper
conveying coil.
6. Because of the magnetic pole positioning of the Sleeve/Magnet Roller, the developer is
conveyed onto the lower part of the Sleeve/Magnet Roller.
7. The Doctor Blade then controls the height of the developer brush.
8. Toner sticks to the electrostatic latent image on the surface of the PC Drum.
9. The developer that is left on the Sleeve is returned to the upper conveying coil by the
magnetic pole positioning of the Sleeve/Magnet Roller.
