Workcentre 6400 Series Codes
Soft Faults: Soft faults are events that occur within the system and, in most cases cause no disruption to the operation of the printer. The system automatically recovers from these events and no action is required by service.
Hard Faults: Hard faults are events that occur within the system that shut down one or more functions within the printer and require service for corrective action.
The Fault Codes Summary table lists possible errors, along with the corresponding code, and page reference for the corrective procedure.

Troubleshooting
This section contains procedures to help you locate and resolve problems. Some problems can be resolved by simply restarting the printer.
Printer Does Not Turn On
- The power switch is not correctly turned on. Turn off the printer using the power switch visible on the lower center tray. Wait two minutes, then turn the printer on. Ensure that the main power switch behind the front cover of the printer is in the on position.
- The power cord is not correctly plugged into the outlet. Turn off the printer, and plug the power cord securely into the outlet.
- Something is wrong with the outlet connected to the printer. Plug another electrical appliance into the outlet and see whether it operates properly. Try a different outlet.
- The printer is connected to an outlet with a voltage or frequency that does not match the printer specifications.
Printing Takes Too Long
- The printer is set to a slower printing mode (for example, heavyweight stock). It takes more time to print with special media. Make sure that the media type is set properly in the printer driver and at the printer control panel.
- The printer is in power saving mode. It takes time for printing to start in power saving mode.
- The job is very complex. Wait. No action needed.
Printer Resets or Turns Off Frequently
- The power cord is not correctly plugged into the outlet. Turn off the printer, confirm that the power cord is correctly plugged into the printer and the outlet, then turn on the printer.
- A system error occurred. Contact your local Xerox service representative with the fault information.
Printer Is Making Unusual Noises
- The tray is not installed correctly. Open and close the tray you are printing from.
- There is an obstruction or debris inside the printer. Turn off the printer and remove the obstruction or debris. If you cannot remove it, contact your Xerox service representative.
2-Sided Printing Problems
Media or settings are not correct. Make sure that you are using correct media. For details, see Supported Media on page 51. Envelopes, labels, gloss, and extra heavyweight stock cannot be used for 2-Sided Printing. In the printer driver, choose 2-Sided Printing.
Scanner Error
Scanner is not communicating. Turn off the printer using the power switch visible on the lower center tray. Wait two minutes, then turn the printer on. If the problem is not resolved, contact your local Xerox service representative.
