CAUSE:
The speed of the transport belt is faster than the feed-in motor speed, even if
both motor speeds are within specification.
SOLUTION:
1. Feed-in motor speed adjustment
Adjust the feed-in motor speed so that the motor speed becomes higher
(within specification).
1. Turn DIP SW 101-1,2,4 to "ON".
2. Turn DIP SW 102-1 to "ON".
3. Turn VR 103 toward "H" to turn LED 101 (Red) on.
4. Turn VR 103 toward "L" to turn LED 102 (Green) on.
2. Transport belt motor speed adjustment
1. Turn DIP SW 101-1,2,4 to "ON".
2. Turn DIP SW 102-2 to "ON".
3. Turn VR 104 toward "L" to turn LED 103 (Red) on.
4. Turn VR 104 toward "H" to turn LED 102 (Green) on.
6. Light Copies
SYMPTOM:
Light copies - toner hopper becomes empty - "Toner End" indication.
CAUSE:
Defective Toner End Sensor.
Normally, the mylar [A] on the toner hopper agitator shaft scrapes the Toner
End Sensor Surface [B] to keep the surface clean. However, if the pressure
between the sensor and the mylar is too high, the sensor may be damaged.
If this occurs, the machine judges that there is toner in the hopper even if the
hopper is empty.
Solution:
We recommend performing step (2) of
this countermeasure at machine setup /
installation.
(1) Replace the Toner End Sensor [A]
(P/N AW31 0003).
(2) Since replacement of the cleaning mylar
is impossible, add (2) 0.5mm washers [B]
as shown (P/N 0708 0030B: thickness =
0.5mm inner diameter = 3.2mm, outer
diameter = 6mm). This will reduce the
pressure between the Toner End Sensor
and the cleaning mylar.
UNITS AFFECTED:
All FT6645/6655 copiers manufactured after
serial number A33544200001 & A3364420032 respectively will have a new
Toner End Sensor Cleaning Mylar installed during production to prevent the
above mentioned symptom.
