Detection Timing
1st Drawer Paper Take-Up Sensor PC56 is not blocked (L) even after
the lapse of approx. 2.2 sec. after 1st Drawer Paper Take-Up Motor M11
has been energized.
2nd Drawer Paper Take-Up Sensor PC57 is not blocked (L) even after
the lapse of approx. 2.2 sec. after 2nd Drawer Paper Take-Up Motor
M12 has been energized.
PC56 is not unblocked (H) even after the lapse of T (which varies for
paper sizes) after it has been blocked (L).
PC57 is not unblocked (H) even after the lapse of T (which varies for
paper sizes) after it has been blocked (L).
1st Drawer Vertical Transport Sensor PC63 is not blocked (L) even after
the lapse of approx. 2 sec. after PC56 has been blocked (L).
2nd Drawer Vertical Transport Sensor PC64 is not blocked (L) even
after the lapse of approx. 2 sec. after PC57 has been blocked (L).
PC54 is not blocked (L) even after the lapse of approx. 1.3 sec. after
PC63 has been blocked (L).
PC54 is not blocked (L) even after the lapse of approx. 1.7 sec. after
PC64 has been blocked (L).
Detection Timing
PC54 is not blocked (L) even after the lapse of approx. 2.5 sec. after
Manual Feed Paper Take-Up Clutch CL3 has been energized.
Detection Timing
PC54 is not unblocked (H) even after the lapse of T (which varies for
paper sizes) after the TRON signal has been input.
PC55 is not blocked (L) even after the lapse of approx. 1.2 sec. after
PC54 has been blocked (L).
PC55 is not unblocked (H) even after the lapse of approx. 1.2 sec. after
