CANON CLC1100/1130/1150/1160/1180 REV.1 JAN. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON)
Timing of detection
0001 During copying, the drawer
connect signal (FT-CNCT*)
of the transfer unit lever is '1'.
0002 During copying operation, the
connection signal (TD-CNCT)
of the drawer connector of the
transfer unit is '1'.
0003 During copying, the drawer
connect signal (CONNECT*)
of the registration path unit is
'1'.
0000 The transfer drum HP sensor
does not go '1' when the
transfer drum locking motor
has been kept on for a specific
period of time.
0001 The transfer drum HP sensor
does not go '0' when the
transfer drum locking motor
has been kept on for a specific
period of time.
0000 The transfer drum cleaner HP
sensor does not go '1' when
the transfer drum cleaner
locking motor has been kept
on for a specific period of
time.
0001 The transfer drum cleaner HP
sensor does not go '0' when
the transfer drum cleaner
locking motor has been kept
on for a specific period of
time.
The BD signal cannot be detected
for 1 sec or more when potential
control operation starts.
0000 The laser scanner motor ready
signal (LSMRDY) is '1' for
0.5 sec or more while the laser
scanner motor is rotating.
0001 The laser heater temperature
has exceeded 60ºC.
0002 When the machine internal
temperature is 20ºC or more,
the laser heater does not reach
a specific temperature within
20 min.
An error has occurred while wiring
data to the laser controller PCB from
the CPU PCB at power-on.
0000 At powe-on, a read/write error
occurred in the register of the
DC driver PCB.
