Paper feed control

A. Pick-up control
• The paper feed motor (M41) starts to rotate upon receiving a print start signal [1].
• After the specified time passed from when the start signal is received [1], the pick-up solenoids /1 (SD7), /2
(SD8) and /3 (SD9) and the paper feed clutches /1 (MC7), /2 (MC9) and /3 (MC11) are turned on.
• When the SD7, SD8 and SD9 turn on, the pick-up roller descends and presses the paper by its own
weight.
• The pick-up roller rotates to feed the top sheet to the paper feed roller by means of the M41 drive force
transmitted via the MC7, MC9, and MC11.
• The subsequent feeding by the pick-up roller is made when the paper feed sensors /1 (PS29), /2 (PS35),
and /3 (PS41) detect the rear end of the previous paper [3].
