Detection Timing
Encoder pulses are not input to SCP Board PWB-IC at
50-msec. intervals while M31 is turning.
Scanner Reference Position Sensor PC55 is not blocked
([H]) despite the fact that the M31 encoder pulse count
represents that the Scanner is at a position 5 mm or
more to the rear (to the right as viewed from the front)
from its home position.
Scanner Reference Position Sensor PC55 is blocked
([L]) when the M31 encoder pulse count is a value that is
equivalent to the Scanner at a position 12 mm before its
home position.
Detection Timing
<Metric Areas>
• 2nd Drawer Paper Lift-Up Sensor PC41 is not blocked
([L]) even after the lapse of 5 sec. after 2nd Drawer
Lift-Up Motor M25 has started turning.
• PC41 is not blocked ([L]) even when 2nd Drawer Lift-
Up Motor Pulse Sensor PC26 detects 150 HIGH-going
and LOW-going edges after M25 has started turning.

blocked ([L]) even after the lapse of 5 sec. after M25
has started turning backward (for downward motion).
• PC19 is not blocked ([L]) even when PC26 detects 150
HIGH-going and LOW-going edges after M25 has
started turning backward (for downward motion).
• PC19 is not unblocked ([H]) even after the lapse of 1.5
sec. after it has been blocked ([L]) while M25 is turning
backward (for downward motion).
• PC19 is not blocked ([L]) even after the lapse of 5 sec.
while M25 is turning forward (for upward motion) after
the drawer has been unlocked.

sec. after it has been blocked ([L]) while M25 is turning
forward (for upward motion) after the drawer has been
unlocked.

of 10 sec. after PC19 has been unblocked ([H]) while
M25 is turning backward (for downward motion).
