CHAPTER 4 OPERATION

5.3 Feeding Operation/Delivery Operation
5.3.1 Outline
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 opera-
tions 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, fix-
ing pressure roller, and delivery roller.

5.3.2 Auto Delivery Control
The machine drives the main motor (M1) for a specific period of time to feed/delivery
roller when the power is turned on, when the reader unit is returned to its initial position, or
when it shifts from ESS mode, in addition to the following:
a. after starting the main motor (M1), the paper leading edge sensor (PS102) detects paper.
b. the size of the paper delivered last is B5 or smaller, and the delivery sensor (PS3) detects
paper after the main motor (M1) is started.
