• If the result is level 2, level 1, or level 0,
clean the sensor or its mounting condition.
• If the result is still level 1 after cleaning
the sensor and checking its mounting con-
dition, be ready for the replacement of the
sensor.
• If the result is level 0 after cleaning the
sensor, checking its mounting condition,
and adjusting it once again, replace the
sensor.
7) Press SW104 on the finisher controller
PCB.
• The press will complete the adjustment.
• Tray B will move up to its initial position.
8) Turn off the power, and shift all bits of
SW103 to OFF.
7. Adjusting the Swing Guide Speed
Perform the adjustment if you have re-
placed the EEPROM (IC102) on the finisher
controller PCB or the swing motor (M8) or
parts associated with it.
1) Set SW103 on the finisher controller PCB
as follows:
Figure 5-117
2) Press SW104 on the finisher controller
PCB.
• This will start automatic adjustment, and
the swing guide will make several swing-
ing operations.
• The output voltage to the swing motor
Indicates
that the
sensor
output
level is
adequate. Indicates
that the
sensor
output
level is
starting to
lower. Indicates
that the
sensor
output
level is
near the
limit for
use.
Level 3 Level 2 Level 1
Indicates
that the
sensor
output
level is
below the
limit for
use.

drive circuit will automatically be ad-
justed so that the time (T1) between when
the swing motor drive starts and the swing
guide closed sensor (PI15) turns off will
be as indicated.
3) When the automatic adjustment has
ended, check LED101 on the finisher con-
troller PCB to find out the result:
• If the output voltage has been adjusted so
that T1 is the optimum value, data repre-
senting the output voltage will be indi-
cated. (in 3 digits, 000 through 255)
• If the output voltage has been adjusted so
that T1 will be shorter than the optimum
value, 'F' and '1' will be indicated in se-
quence.
• If the output voltage has been adjusted so
that T1 will be longer than the optimum
value, 'F' and '2' will be indicated in se-
quence.
4) Press SW104 on the finisher controller
PCB.
• This will complete the adjustment.
• If T1 is longer or shorter, the default out-
put voltage will be selected.
5) Turn off the power.
6) Shift all bits of SW103 to OFF.
Reference:
If the swing guide has been used for a
long time and, as a result, the sound of
the guide moving up increases, perform
this adjustment so that the motor drive
speed will be optimum, reducing the
sound.
8. Indicating the Swing Guide Speed
Use this mode to find out the time taken
by the swing guide to move up or move down;
if jams occur frequently near the swing guide,
check the time taken for these movements.
1) Set SW103 on the finisher controller PCB
as follows:
