Code Description / Procedure
N4A Y-Axis motor stalled on power-up following an abnormal shutdown.
N4B Y-Axis motor stalled on power-up following a normal shutdown.
N4C Y-Axis motor stalled during mechanical recovery
N4D Y-Axis motor stalled during warm-up.
NFE Y-Axis motor stalled during ready state.
N4F Y-Axis motor stalled during a fault state.
N4G Y-Axis motor stalled during an auto drum maintenance cycle.
N4H Y-Axis motor stalled during printhead maintenance.
N4J Y-Axis motor stalled during printhead purge.
N4K Y-Axis motor stalled during an oil transfix roller cycle.
N4L Y-Axis motor stalled during standby mode.
N4S Y-Axis motor stalled during staging for transfix.
N4T Y-Axis motor stalled during transfixing.
N4V Y-Axis motor stalled during a print drum maintenance cycle.
N4W Y-Axis motor stalled during drum imaging.
N4X Y-Axis motor stalled during paper exit.
1. Check for supported media, generally label, trifold or envelopes cause this error.
2. Try running fewer sheets through the tray.
3. Check that the Process Drive is correctly homed (ADJ 4.7.1).
4. Test theY-Axis Motor using Service Diagnostics, replace if necessary (REP
4.0.11).
5. Test for Y-Axis Belt slippage using the Belt Slip test.
6. Replace the Tray 1 Separator Pad assembly.
7. Replace the Process Drive (REP 4.0.7).
N5T Y-Axis motor out of position during transfixing.
N5W Y-Axis motor out of position during drum imaging.
1. Check the Y-Axis drive belt.
2. Run the Check Drum Y-Axis Encoder test.
3. Run the Check Drum Y-Axis Drive test.
4. Test for Y-Axis Belt slippage using the Belt Slip test.
5. Replace the Y-Axis Motor (REP 4.0.11), or Drum Assembly (REP 2.0.3) if neces-
sary.
N6T Y-Axis Motor media short during transfix. The media was shorter than expected. Legal
size paper from Tray 4 in standard print mode may buckle. Use slower print mode.
1. Check for supported media.
2. Check system grounds.
3. Run the Check Drum Y-Axis Encoder test.
4. Remove the Preheater (REP 2.0.17), and check the Preheater flag for ink or
paper interference.
5. Replace the Preheater (REP 2.0.17).

Code Description / Procedure
N7T Y-Axis Motor media long during transfix. The media was longer than expected.
1. Check for supported media.
2. Try heavier media.
3. Try loading only a few sheets. Some photo media may require running one sheet
at a time.
4. Run the diagnostic Check Drum Y-Axis Encoder test.
5. Replace the Pick Assembly and Retard Roller (REP 3.0.18).
6. Run the clean ink smears and check the Preheater exit flag for debris.
7. Remove the Preheater (REP 2.0.17), and check the Preheater flag for ink or
paper interference.
8. Replace the Preheater (REP 2.0.17) if the error persists.
