Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
CAUTION
Use care when working near the drum. The drum can be damaged easily, which will cause
print quality defects.
• Check that the print media loaded into all of the trays matches the UI display for each tray.
If necessary correct the settings or load the correct media. Media that is too thick for the
machine settings will cause drive errors.
• Check the trays for mixed media weights and correct if necessary.
• Check for evidence of multi-feeds. Multiple sheets of media may cause drum drive errors.
If multi-feeds are indicated go to
OF 8 Multi-feed RAP.
• Check the fault history for Mis-Feed Jam fault codes 71-101-00 to 71-155-00, 72-101-00
to 72-155-00, 73-101-00 to 73-155-00, 74-101-00 and 75-101-00. If the fault codes are
present then perform the appropriate RAP before proceeding with this RAP.
• Check the fault history, dC122 for 10-500-00 to 10-540-00 or 10-550 fault codes. If the
fault codes are present, perform the appropriate RAP before proceeding with this RAP.
• Enter dC978 Transfix Calibration Values. Check the calibration values against the label
on the front of the drum frame. If necessary, enter the correct transfix load values.
NOTE: The calibration values are found on a label on the drum frame behind the inner
cover,
PL 81.11 Item 2 .
Procedure
Go to dC123 Pest Fault History and check for faults related to the drum, drum drive or drum
control components.
Refer to Figure 1 . Perform the following:
1. While the transfix roller is not loaded, spin the roller. Check that the roller spins freely
without binding or generating unusual noise. Check the surface of the transfix roller for
contamination or damage. Install new components as necessary,
PL 10.20 .
2. If 10-536 is in the fault history, dC122 , check the transfix calibration values, dC978 . If the
transfix values have been reset, re-enter the correct transfix values.
NOTE: The calibration values are found on a label on the drum frame behind the inner
cover,
PL 81.11 Item 2 .
3. Switch off the machine, then switch on the machine, GP 14 . Check for, power supply,
drum motor thermal protection circuit and drum motor current feedback PEST faults then
perform the relevant RAP.
4. Check the fault history, dC122 for 94-550 or 94-551 faults. If either fault is present, per-
form the relevant RAP.
5. Remove the drum and abatement fan assembly, refer to REP 91.24 . Manually rotate the
drum and observe the drum motor. Abrupt rotations of the drum motor about its tensioning
pivot indicates problems with the drum belt, such as voids or contamination in the
grooves.
6. Check the drum belt tensioner mechanism. Make sure that the tensioner is latched cor-
rectly and applying tension to the motor bracket. Inspect the motor bracket for free rota-
tion around its pivot, allowing tension to be transmitted to the drum belt.
7. Release the drum belt tension. Make sure that the drum drive motor pivots freely.
8. With the drum drive and transfix roller disengaged from the drum, manually rotate the
drum. If the drum does not rotate freely, install new components as necessary:
• Drum, PL 94.20 Item 1 .
• Drum pulley, PL 94.20 Item 3 .
9. Remove the drum drive motor and drum belt, REP 91.24 . Perform the following:
Perform the necessary actions:
• Clean the drum pulley, GP 27 .
• Clean the drum belt, GP 27 .
• Clean the drum drive motor pulley, GP 27 .
• If necessary install a new belt, PL 94.20 Item 2 .
10. Check system grounds, refer to GP 7 . Pay particular attention to the media path baffles,
transfix roller, and drum ground connections.
11. Refer to WD 1.1 and WD 9.3 . Perform the following:
a. Check the wiring between PJ6AC and the drum drive motor. Repair as necessary,
REP 1.1 .
b. Check the drum driver power supply interface cable, PL 1.15 Item 10 . If necessary,
install a new drum driver power supply interface cable, PL 1.15 Item 10 .
c. Check the wiring between the drum drive motor encoder and the Drum driver PWB ,
PJ802. Repair the wiring as necessary, REP 1.1 . If necessary install a new cleaning
unit interface harness (PJ601, PJ802), PL 1.15 Item 17 .
12. Install new components as necessary:
• Drum drive belt, PL 94.20 Item 2 .
• Drum position encoder assembly, PL 94.20 Item 8 .
• Power supply unit, PL 1.15 Item 2 .
• Drum driver PWB, PL 1.15 Item 4 .
• Drum drive motor, PL 94.20 Item 6 .
• IME controller PWB, PL 92.10 Item 1 .
