PAPER PICK-UP/FEED SYSTEM
4.1 Outline
If a tray1 paper pick-up roller solenoid drive signal (PUCL1) is input to the circuit while the paper
feed motor is rotating, the paper pick-up solenoid comes on and the paper pick-up roller solenoid
is engaged. As a result, the paper pick-up roller rotates to feed paper down to the photosensitive
drum.
The paper position is controlled by the registration sensor so that the leading edge of the paper
is aligned with the leading edge of the image on the photosensitive drum. After this operation,
the paper is deliveried to the face down tray via the fixing unit. Paper ejection is detected by the
paper ejection sensor; if printed paper has not reached or not cleared the paper ejection sensor
in a specified time, the printer judges that a paper jam has occurred. In this case a paper jam
is noticed to the external devise by a status signal.
