2.1 Basic Operation
2.1.1 Outline
Paper Deck (hereafter, deck)
Number of sheets :2700 (A4/LTR/B5; paper of 80 g/m2)
2.1.2 Pickup Operation
The paper placed inside the deck is held up by the lifter, and is kept in position at a specific height.
When the Start key is pressed, the deck pickup clutch (CL2) goes ON. Then, the deck main motor (M1) goes ON, and the rotation of the pickup roller moves the
paper into the machine.
The pickup/feeding roller and the separation roller make sure that no more than a single sheet of paper is picked up.
After the deck pickup sensor (PS6) has detected the presence of paper, the pickup roller leaves the surface of paper when the deck pickup roller releasing solenoid
(SL1) goes ON.
When paper is fed, the deck feed roller rotates to move the paper to the registration roller of the host machine, where the paper is looped so that it does not skew.
The registration roller is controlled so that the image on the photosensitive drum and the leading edge of the paper will match.
<if pickup is not detected within a specific period of time>
If, for some reason, the deck pickup sensor (PS6D) does not detect paper in the presence of the deck pickup detection signal, the machine will issue an alarm code.
