After replacing the
Scanner Drive
Wires, be sure to
perform optics free
run. Then perform
the Scanner Control
Adjustment.

If the Horizontal Lens
Drive Motor vibrates,
check here (see below).
•
Figure 1. If excessive wear or breakage occurs to the Exposure Lamp
Harness, refer to TSB’s FT6645/55/65 - 13, 21 update no. 2 and 54 update
no. 3
•
Figure 2. After replacing the Scanner drive wires, be sure to follow
the procedures on FSM page 5-31 and 32.
Failure to do so may result in
jams at the registration sensor.
•
Figure 3. If the Horizontal or vertical lens drive motors vibrate and generate
a lens drive SC code, carefully inspect the solder joints and connectors on the
harnesses that supply the stepper motors.
When the lens stepper motors are not
rotating, 24 volts should be available at all the pins supplying the motor.
•
Figure 4. Scanner motor failure can cause SC 125, erratic operation and
registration jams.
•
If the Scanner Drive Wires come off during operation: Refer to, TSB’s
FT6645/55/65 - 7R, 31R, 39 update 3. also refer to “Common Transfer Unit
Problems” and “Common Drum and Development Unit Problems”
NOTE:
Registration jams can occur due to a problem in the optics
1. Binding in the scanner.
2. Incorrect drive wire tension.
3. Electrical noise generated by the scanner drive motor.
4. Improperly set scanner control adjustment.
These can all cause registration jamming. Reason: Registration timing is
based on optics timing, if the optics is functioning at the incorrect speed,
registration timing will be incorrect, resulting in a jam.
