Fault criteria
1. If the scanner is not at the home po-
sition (SCHP=0) when the COPY
START key is pressed.
If the scanner does not return to the
home position (SCHP remains 0)
within 15 sec (A4 size) after it starts
to reverse.
2. If the scanner is in the home posi-
tion (SCHP=1) when the COPY
START key is pressed.
• If the scanner does not leave the
home position (SCHP remains 1)
within 1.5 sec after it starts to ad-
vance.
• If the scanner does not return to the
home position (SCHP remains 0)
within 1 sec after it leaves the home
position (SCHP=0).
If the No. 4 and No. 5 mirrors do not
reach home position after 8 sec from
driving starts.
• If the lens does not return to the
home position (LHP remains 0)
within 2.5 sec
• If LHP remains 1 for at least 4 sec.
At the lamp ON timing, LAON=1 is
not true.
At the lamp OFF timing, LAON=0 is
not true.
If the data in EEPROM has been re-
written more than specified.
If the main frequency is out of the al-
lowed range.
If ADF remains 0 for 12 sec or longer.
• If the copier does not communicate
with the sorter for at least 12 sec.
• If the SORTER STANDBY signal
does not return within 35 sec after the
BCR signal is outputted.
If the AC power is not off when the
DC controller PCB generates the
ACCOFF signal.
