9.8.3.2 Secondary External Roller
The secondary transfer external roller is cleaned electrostatically.
Description of Control
A bias is applied to the secondary transfer external roller alternately using the polarity used for image
formation and the polarity opposite it for longer than the time it takes the roller to make a single rotation,
thereby returning the toner remaining on the roller to the ITB.
Timing of Control
1. when a copy/print job ends.
2. after recovery from a jam.
3. when a sample image (or test pattern) is formed as part of image stabilization control.
9.8.3.3 Waste Toner Collection Mechanism
Waste toner is collected by the following mechanisms:
- waste toner
scraped by the cleaning blade and fed to the waste toner box by the waste toner feeding screw.
- waste toner box full detection
detected by the waste toner sensor composed of the LED (light emission) and the photo-transister (light
reception).
