MAIN BODY
Paper feed is carried out by transmitting the drive of the
M100 (Paper feed motor) to the upper and lower paper
feed rollers and to the feed rollers. When feed starts,
SD101 (1st. paper feed SD (upper)) or SD102 (1st. paper
feed SD (lower)) raises and lowers the feed roller and
contacts the paper.
Drive of the M100, SD101 and SD102 is carried out by
PFUDB (PFU drive board)and controlled by the main
body.
No paper detection is carried out with PS103 (No paper
detect PS (upper)) and PS108 (No paper detect PS
(lower)) and controlled by the main body via the PFUDB.
