7) If the result is 'NG', press SW976 on the
switch PCB to execute the adjustment
once gain.
8) If 'NG' is indicted after several attempts,
check the following:
•
Belt of the swing guide motor for ten-
sion.
•
Swing guide closed sensor (PI5) for
mounting condition.
If the swing guide has
started to wear and, as a
result, the noise of the
Memo
guide increases when it
moves up/down, execute
this adjustment to correct
the motor drive speed; the
noise may decrease.

1.1.7 Indication for the Swing Guide
Speed
You can measure, evaluate, and indicate
the time it takes the swing guide to move up
or down using this mode. If jams occur of-
ten near the swing guide, check the time
length:
1) Set SW973 on the finisher controller
PCB as indicate:
ON
1 2 3 4 5 6 7 8
F05-101-15
2) Press SW976 on the PCB.
•
The switch guide performs several
swinging operations, and the machine
automatically measures the time it takes
the guide to move up/down.
3) When the up/down movement of the
swing guide ends, check DSP971 the
PCB for the result.
•
If the reading of DSP971 is '0', the re-
sult is within standards.
•
If the reading of DSP971 is 'F', on the
other hand, the result is outside the stan-
dard.
4) Press SW975 or SW974 on the PCB.
•
DSP971 indicates the time length of as-
cent and the time length of descent.
•
A press on SW75 brings up the ascent
time length, while a press on SW974
indicates the descent time length.
•
In the case of ascent time length, the
indication will be 'a', 'b', and 'c' in se-
quence.
•
In the case of descent time, the indica-
tion will be 'a', 'b', and 'c' in sequence.
