CHAPTER 5 PICK-UP/FEEDING SYSTEM

B. Identifying the Size of Paper on the Multifeeder

The width of copy paper is identified by a variable resistor (VR1) which operates in response to the location of the slide guide, which is adjusted by the user to suit the size of paper.

The identified width of copy paper is used for blank exposure control.

The length of paper when the multifeeder is used is identified by the period of time during which the registration sensor (PS6) remains on.

The data collected in such a way is used to control the length of blank exposure, activation of the registration roller, and high voltage.

Reference:

The maximum length of paper is 432 mm (LDG size); paper longer than this will

lead to a jam.
