Error Codes List page 50

  • Code: OF 1-4
  • Description: AC Input Power There is an AC input power failure between power cord and AC Drive PWB.
  • Remedy: • Entry to this RAP is from Call Flow. • Check that the required voltage is available at the customer power outlet (approx. 110 VAC or 220 VAC). Inform customer if power is not available.
    AC Line Voltage is measured between the GFI Breaker P/J72-2 (+) and P/J72-1 (-) (refer to HVPS, +24V LVPS T10 Plug/Jack Locations ). Y↓N→Check the Power Cord for an open circuit. If no problems are found, replace the GFI Breaker (PL 9.2). Measure voltage between P/J39-1 (ACH/BLK) and P/J39-3 (ACN/WHT) on the AC Drive PWB (refer to AC Drive PWB, Noise Filter PWB Plug/Jack Locations ). AC Line Voltage is measured. Y↓N→Check the connections between the GFI Breaker and the Noise Filter PWB. If the connections are good, push the small button to reset the GFI Breaker. If it is not tripped, replace the Noise Filter PWB (PL 9.2). Measure voltage between J57 (ACH) on the Main Power Switch and J40 (ACN/WHT) on the AC Drive PWB. AC Line Voltage is measured. Y↓N→Repair the open circuit between the Main Power Switch and the AC Drive PWB. Hold the Main Power Switch in the on position while measuring voltage between J69 (ACH) on the Main Power Switch and J39-1 (ACN/WHT) on the AC Drive PWB. AC Line Voltage is measured. Y↓N→Replace the Main Power Switch (PL 10.2). Hold the Main Power Switch in the on position while measuring voltage between P/J41 (ACH/ BLK) and P/J40 (ACN/WHT) on the AC Drive PWB. AC Line Voltage is measured. Y↓N→Repair the open circuit between the AC Drive PWB (PL 9.2) and the Main Power Switch (PL 10.2). AC input power to the AC Drive PWB is good.
  • Code: OF 10-1
  • Description: No Printer Top Tray Offset Sets are not offset in Printer Top Tray.
  • Remedy: Enter Service Diagnostics Menu: Printer Menu > Troubleshooting > Service Tools > Printer Status Page > hold the Up and Down buttons simultaneously > Run Service Diagnostics > OK. Perform the Offset Motor test. Y↓N→Check the circuit of the Offset Motor. Repair the offset components as required (PL 2.11).
  • Code: OF 10-16
  • Description: Noise/Odor RAP The machine produces noise or odor.
  • Remedy: The machine produces noise. Y↓N→Then odor is produced. Identify the source of the odor such as the Fuser (PL 7.1), AC Input Power area (PL 9.1 - PL 9.3), Paper Trays (PL 2.1), Xerographics (PL 4.1 - PL 6.2). Service as required. The Left Cover Assembly is free of noise. Y↓N→Refer to PL 2.8, Exit Roll Shaft, and clean and lubricate the bearings. Operate machine with covers removed to identify the source of noise. Clean or lubricate the appropriate component. Operate Motors on sub-system individually to isolate the noise to a particular mechanism.
  • Code: OF 12-1
  • Description: Finisher Problem There is a problem with the Finisher that does not produce a fault code.
  • Remedy: The machine is equipped with an Advanced / Professional Finisher. Y↓N→Refer to the Parts List to repair the Finisher problem. • Major Finisher Components • Gate Assembly • H-Transport • Covers • Top Cover and Eject Rolls • Paper Transportation • Stapler within Finisher • Convenience Stapler • Compiler • Elevator • Exit Assembly • Electrical Components • Rack Assembly (base) Refer to the appropriate procedure to adjust the Finisher. • ADJ 12.2 Finisher Leveling • ADJ 12.4 Booklet Fold Skew • ADJ 12.5 BookletFold Position • ADJ 12.6 Booklet Staple Position (Staple on Fold) • ADJ 12.7 Booklet Staple Alignment • ADJ 12.8 Booklet Wrinkle • ADJ 12.9 Booklet Fold Position (Fine Adjustment) • ADJ 12.10 Booklet Staple Position (Staple on Fold Fine Adjustment)
  • Code: OF 7-1
  • Description: Paper Trays A paper tray problem occurs without a status or fault code.
  • Remedy: Ensure the protective shield is removed from the rear of the paper trays in the 3 Tray Module or Tandem Tray Module. NOTE: The shield protects the paper size actuators during shipping.
  • Code: OF 99-3
  • Description: Switch
  • Remedy: Actuate the Switch. The display changed. Y↓N→There is +3.5/+5 VDC measured between Pin 2(+) of the Switch and GND(-). Y↓N→Check the wire between the switch Pin 2 and the PWB Pin 3 for an open circuit and poor contact. If the check is OK, replace the PWB. There is +3.5/5 VDC measured between Pin 1(+) of the Switch and GND(-). Y↓N→Replace the Switch. Check the wire between the PWB Pin 4 and the switch Pin 1 for an open circuit and poor contact. If the check is OK, replace the PWB. De-actuate the Switch. The display changed. Y↓N→Disconnect the connector on the Switch. The display changed. Y↓N→Check for a short between the switch Pin 2 and the PWB Pin 3. If the check is OK, replace the PWB. Replace the Switch. Replace the Switch.
