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 solenoid /BP (SD5)
and the paper feed clutch /BP (MC6) are turned on [2].
• When the SD5 turns 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 MC6.
• The subsequent feeding by the pick-up roller is made when the paper feed sensor /BP (PS26) detects the
rear end of the previous paper [3].
