7.5 Delivery
7.5.1 Outline
0006-4095
The machine uses the following to feed/deliver paper:
- registration roller
- photosensitive drum
- transfer charging roller
- fixing pressure roller
- delivery roller
The paper moved as far as the registration shutter by the work of the various pick operations is corrected for skew
movement when it is butted against the registration roller.
When the paper moves past the registration assembly, the paper leading edge sensor (PS102) detects its leading edge,
thereby ensuring that the leading edge of the paper will match the leading edge of the image on the photosensitive
drum. Thereafter, the paper is moved past the photosensitive drum and then is moved over the transfer charging
roller, fixing pressure roller, and delivery roller.
