How to reset the photoconductor page count



Whenever you replace the photoconductor unit, you will also need to reset the page count on the unit.  Failure to do this will cause the printer to continue displaying a Replace photoconductor kit message. Also, once the photoconductor page count reaches a certain point, the printer will stop printing and display a photoconductor exhausted message. This can occur even after installation of a brand-new photoconductor unit if the page count is not reset at the time the new unit is installed. 

The photoconductor page count should be reset only when a brand-new photoconductor kit is installed.  Resetting the page count without  replacing the photoconductor kit could cause the photoconductor to operate beyond its intended life and create print quality issues.

To reset the photoconductor page count:

  1. Turn off the printer.

  2. While the printer is off, press and hold the Select () and Return () buttons on the operator panel. 


  3. While keeping both buttons held down, turn the printer back on. Keep holding down both buttons until the printer screen displays Performing Self Test or CONFIG MENU.

  4. Release the buttons when you see either of these messages.

  5. If Reset PC Cnt does not then appear on the screen, press the left or right menu button until it does. 


  6. Press the Select button once. The message Resetting PC Cnt Value should briefly appear on the screen, indicating that the photoconductor page count has been reset.

  7. When the display shows CONFIG MENU again, power off the printer.

  8. Wait five or more seconds and then power the printer back on. NOTE: Do not hold any buttons down when powering on the printer during this step.
    The photoconductor page count should now be reset.  At this point, it is recommended that you print a menu settings page to confirm this. Do the following:

    1. With the printer at the Ready status, press the left or right Menu button until UTILITIES MENU appears on the screen.

    2. With UTILITIES MENU on the screen, press the Select button once. A new menu should appear.

    3. If Print Menus is not displayed on the second line of the screen, press the left or right menu button until Print Menus appears. 

    4. Press the Select button once. The message Printing Menu Settings should appear on the screen and the printer will print out one to three pages of printer settings.  

    5. Look for a heading labeled Cartridge Information on one of the menu settings pages.  

    6. Under Cartridge Information, look for the word Photoconductor. Confirm that the level of the photoconductor says OK or is close to 100%.    

    7. If the photoconductor is still reading low, try printing 10 - 20 more pages.  

    8. Print the menu settings page(s) once more. Confirm that the photoconductor level is now at OK or close to 100%.   

    9. If the photoconductor continues to give a low reading, repeat this entire procedure again from the beginning to reset the counter once more.  

    10. If the photoconductor reading is still low after two attempts to reset the counter, the printer may require service.

Additional information

For additional information about resetting this counter, refer to the instruction sheet that shipped with the new photoconductor kit.


Replacing supply items

There are only two supply items that have to be replaced on a regular basis: the toner cartridge and the photoconductor kit. Together, these items comprise the print cartridge assembly.  The photoconductor kit typically lasts for up to 30,000 letter-size pages (at approximately 5% coverage). The actual page yield of the photoconductor depends on the size of the paper you print on and the average amount of toner coverage on your print jobs.  The photoconductor unit may need to be replaced more often when you print on media of a larger size, such as Legal paper.
Within the United States or Canada, you can order Lexmark supplies from any authorized Lexmark supplies dealer. To locate the dealer nearest to you, call 1-800-539-6275.
