Replacing The Finisher; Controller (In Response To E505); Initializing The Ram - Canon SADDLE FINISHER K3 Service Manual

1.1.12 Replacing the Finisher

Controller
(in response to E505)
1) Turn off the copier.
2) Remove the EEPROM (IC102) from the
new PCB. (Do not dispose of the ROM
as yet.)
3) Remove the EEPROM from the old
PCB, and mount it to the socket of the
new PCB (ICS102).
4) Remove the old PCB from the finisher,
and mount the new PCB to the finisher .
5) Turn on the copier. If the copier does
not indicate 'E055', end the work. (The
contents of the old PCB are backed up
on the new PCB.)
If 'E505' is indicated, go to the follow-
ing step:
® If 'E505' occurs once again, the
EEPROM is faulty. You cannot back up
the memory using the old EEPROM.
6) Turn off the copier, and replace the
EEPROM mounted to the new PCB
with the EEPROM removed and put
aside from the new PCB.
7) Perform the work under 11. "After Re-
placing the EEPROM."

cated:
ON
1 2 3 4 5 6 7 8
F05-101-28
2) To clear the counter only,
Hold down SW976 and SW974 on the
switch PCB at the same time for 3 sec
or more.
To clear all data,
Hold down SW976 and SW975 on the
switch PCB at the same time for 3 sec
or more.
3) Turn off the power, and shift all bits of
SW973 to OFF.
