Switch off the machine, GP 14 . Use a screwdriver to manually rotate the transfix gear, Figure
2 . This action will move the transfix roller. Move the transfix roller onto, then off the drum. Per-
form the action at the front and rear.
•
Check that the transfix mechanisms operate smoothly. Watch for the transfix roller or
encoder moving up and down. Check that the effort to move the front and rear transfix
mechanisms is similar.
NOTE: The transfix motors will give some resistance to movement. If the transfix mecha-
nisms move without any resistance, this indicates a problem.
• While the transfix roller is away from the drum, spin the roller. Check that the roller spins
freely without binding or generating unusual noise.
• Check that the gear train and the transfix bearings are good. Check for excessive move-
ment between the linkage arm and the pin. This is caused by missing or worn bushing
inside the front or rear transfix linkage assembly,
PL 10.20 Item 8 and PL 10.20 Item 10 .
The transfix components are good.

Install new transfix components as necessary,
PL 10.20 .
Switch on the machine, GP 14 . Check dC123 PEST Fault History if a fault is displayed. Enter
dC140 Analog Monitor. Use a screwdriver to manually rotate the front and rear transfix gears.
Monitor all encoders:
•
10-010 Rear transfix flexure encoder.
• 10-011 Rear transfix motor encoder.
• 10-012 Front transfix flexure encoder.
• 10-013 Front transfix motor encoder.
• Manually move the front and rear flexure encoder harness wires. A good encoder is indi-
cated by a value between 5 and 100 ticks.
If more than 100 ticks, check for loose encoder or intermittent short.
If less than 5 ticks, check for open or missing code strip.
Repair the harness as required, REP 1.1 .
The display changes for all encoders.

Refer to
WD 9.1 and WD 9.3. Check and the wiring between the drum driver PWB and the
relevant transfix flexure motor encoder. Repair as necessary. REP 1.1 . Refer to:
• PJ 401, PJ 501, PJ 801, Drum Driver PWB .
• 01D +5V Distribution RAP
• 01L 0V Distribution RAP
If the wiring is good, install new components as necessary:
• Transfix flexure encoder, PL 10.20 Item 5 .
• Transfix motor, PL 10.20 Item 11 .
• Drum driver PWB, PL 1.15 Item 4 .
Enter dC330 codes 10-019 and 10-020 to run the front and rear transfix motors. When the
motors run the transfix drive arms will move up and down approximately 10 times. The
motors run.

Refer to
WD 9.1 . Check the relevant motor. Refer to:
• GP 10 How to Check a Motor.
• PJ401, Drum driver PWB.
• 01J +50V Distribution RAP.
• 01L 0V Distribution RAP.
Install new components as necessary:
•
Transfix motor, PL 10.20 Item 11 .
• Drum driver PWB, PL 1.15 Item 4 .
Enter dC962 Transfix Load Test and run the test. The transfix load test passed.

If errors are indicated, check out the fault description displayed.
If the fault still occurs, perform the following:
1. For fault codes 10-500 or 10-505, make sure that the relevant transfix encoder screws are
tight and the relevant transfix encoder is secured to the frame.
2. Recheck the fault code description, use it to aid in identifying which link assembly is at
fault. Inspect for worn or damaged gears and check for a cracked linkage. Install new
components as necessary:
• Front compound gear, PL 10.20 Item 7 .
• Front transfix linkage assembly, PL 10.20 Item 8 .
• Rear compound gear, PL 10.20 Item 9 .
• Rear transfix linkage assembly, PL 10.20 Item 10 .
3. Check the transfix roll ground wire, refer GP 7 System Grounding Verification.
