Paper Feeder; Outline - Canon CLBR 460ps Service Manual

CHAPTER 2
VIII. PAPER FEEDER
A. Outline
The paper feeder does not contain a microcomputer (CPU) and is controlled by the DC controller.
The paper feeder does not have a drive motor, so its rollers are controlled by the pick-up motor
(M2) of the printer.
Like the pick-up timing of the printer, the pick-up timing of the paper feeder is based on the
ITB HOME POSITION DETECTION signal. (See P.2-56 for the home position detection.)
+24V and +5V are supplied to the paper feeder from the printer.
