CHAPTER 5 TROUBLESHOOTING
2) Press SW104 on the finisher controller
PCB.
• The swing guide swings several times, and
the time taken for upward and downward
movements will be measured automati-
cally.
3) When the swing guide stops, check
LED101 for the result:
• If LED101 indicates '0', the time is within
the standard range.
• If LED101 indicates 'F', the time is outside
the standard range.
4) Press SW105 or SW106 on the finisher
controller PCB.
• LED101 indicates the times taken for up-
ward and downward movements.
• A press on SW106 indicates the time for
upward movement, a press on SW105 in-
dicates the time for downward movement.
• In the case of upward movement, 'a', 'b',
and 'c' will be indicated in sequence.
• In the case of downward movement, 'a', 'b',
and 'c' will be indicated in sequence.
Where, 'a' indicates the 100's;
b', 10's;
'c', 1's in msec.
Reference:
The standard time for upward movement
is 250 ± 15 msec. The standard time for
downward movement is 320 ± 20 msec.
5) Turn off the power.
6) Shift all bits of SW103 to OFF.
Reference:
If the time is longer, check the swing
mechanism for a mechanical fault.

1) Turn off the copier.
2) Set SW103 on the finisher controller PCB
as follows:

3) Turn on the power.
4) Press SW104 and SW105 on the finisher
controller PCB at the same time.
• This will initialize the EEPROM.
5) Make the adjustments shown in Table 5-
104.
• Alignment width
• Stapling position (front, 1-point stapling)
• Stapling position (2-point stapling)
• Stapling position (rear, 1-point stapling)
• Buffer roller wrapping degree
• Sensor (initial)
• Swing guide speed

10. Replacing the Finisher Controller
PCB (for E505)
1) Turn off the copier.
2) Remove the EEPROM (IC102) from the
new PCB. (Do not throw away the ROM
yet.)
3) Remove the EEPROM from the old PCB,
and fit it into the socket (ICS102) on the
new PCB.
4) Remove the old PCB from the finisher,
and mount the new PCB to the machine.
5) Turn on the copier. If the copier does not
indicate 'E505', end the work (the contents
of the memory on the old PCB have been
backed up on the new PCB). If the copier
indicates 'E505', go to the next step.
If 'E505' recurs, the EEPROM is faulty.
You must not use the old EEPROM to
back up the memory.
6) Turn off the copier, and replace the old
EEPROM mounted to the new PCB with
the new EEPROM.
7) Perform the steps under 9. "After Replac-
ing the EEPROM."
