5.4.1 Malfunction

5.4.1.1 Malfunction/Faulty Detection

5.4.1.1.1 The output is sent to tray B even when
tray A is selected.
[Case Study]
Description
Enabling the following in user mode will select tray
B as the destination of output (large-capacity
stacking mode): initial setup/registration>common
spec setup>large-capacity stacking mode.
Once the setting has been enabled (ON), th target of
output will be tray B, regardless of the selection
made on the control panel.
Field Remedy
Disable (OFF) 'large-capacity stacking mode' in user
mode so that the target of output may freely be
selected on the control panel.
5.4.1.1.2 Remedy for EEPROM Problem on
Finisher Controller PCB
Description
The remedy in case 'E505' is displayed at the time of
Finisher Controller PCB replacement is described
below.
Remedy in the Field
With the following procedure, resolve the
problem.
1) Turning off the copier.
2) Remove the old PCB from the finisher and
mount the new PCB.
3) Remove EEP-ROM (IC107) from the new
PCB. (Do not throw the EEP-ROM away at this
point.)
4) Remove EEP-ROM from the old PCB and set
it into the socket (ICS1) on the new PCB.
5) Turn on the copier. If E505 is not displayed on
the copier, it is the end of the procedure (The
memory contents in the old PCB is backupped to
the new PCB.)
6) If E505 is displayed, go on to the next step.
(If E505 occurs once again, it is due to EEP-ROM
fault. Memory backup using the old EEP-ROM is
not succeeded.)
7) Turn off the copier, and replace the old EEP-
ROM set into the socket on the new PCB to the
new EEP-ROM.
8) Turn on the finisher once again.
9) Turn on the copier, and make it in the standby
state.
10) Open the front door, and insert a door switch
actuator into the door switch [1].
