How to Troubleshoot Xerox Copiers Using Function Codes

Whenever your Xerox brand copier experiences a problem, such as jammed paper or an incorrectly installed toner cartridge, the machine automatically generates a function or error code. Each of these numbered codes corresponds to a specific problem with the copier, such as a bad imaging unit. Knowing which error code corresponds to which problem makes it simple to troubleshoot the problem and get your Xerox copier back up and running.

Skill level:


  1. 1

    Check the Xerox copier's front panel to see what function code is displayed. Check to see if the code is listed as error "01," "02," 03," "80," "81," "82," "83" or "84."

  2. 2

    Unplug the Xerox copier. Pull up the front plastic cover to reveal the toner cartridges. Pull out each of the toner cartridges, then slide them back into place. Replace the cover and plug in the copier.

  3. 3

    Hold the power button until the copier shuts off if the function code reads "05," "10," "11," "12," "13," "50," "51," "70," "71" or "72." Turn on the copier and attempt to copy a document again.

  4. 4

    Unplug the copier and open the front panel if the function code reads error "20," "21," "22," "30" or "32." Contact Xerox to purchase a new imaging unit for your specific copier model.

  5. 5

    Turn the blue knob at the front of the plastic imaging unit counterclockwise. Pull the imaging unit toward you until it catches, then lift up the unit's handle and pull it out of the copier.

  6. 6

    Check to see whether the white plastic sensors behind the imaging unit are dusty. Wipe off the sensors with a soft cloth or the brush tool that came with the new imaging unit. Slide the new imaging unit into the copier and turn the blue locking knob clockwise. Close the plastic cover.

  7. 7

    Lift up the top control panel if the error code reads "33," "40," "41," "42," "43," "52," "53" or "62." Pull out the paper from the output tray and check to see whether there are any visible paper jams.

  8. 8

    Grip the edges of the jammed paper and pull it slowly toward you to remove it from the Xerox copier. Set the paper back into the tray and push the control panel down into place.

Tips and warnings

  • If the function code reads "63," remove and replace the existing imaging unit instead of buying a new one.
  • If your Xerox machine is connected to your network, you can use the Xerox online diagnostic tool to discover the problem. Navigate to the Phaser Smart website and type your copier's IP address in the text box. Follow the on-screen troubleshooting instructions. The IP address can be found by navigating to the "Printer Identification" option in the Xerox's menu.
  • The exact locations of the imaging unit, paper feed and toner cartridges may vary among Xerox models. Check your copier's manual for instructions if you have trouble finding any components.
