If My Error Code States 84 Replace Pc Units, Does It Mean I Have To Replace All?

What you will see

The printer displays an 84 Replace PC Kit message. You replace the PC kit (also referred to as a 'photoconductor unit') with a new one. However, the 84 Replace PC Kit message remains.

NOTE: In some rare cases, a completely new printer will display an 84 Replace PC Kit message when first installed.

Cause

You must reset the photoconductor page count whenever you install a new photoconductor unit. For reset instructions, see the table below.

84 Replace PC Kit and Replace Photoconductor messages indicate that the installed photoconductor unit is nearing the end of its functional life. The printer calculates this page count by measuring the number of revolutions that the roller on the photoconductor makes since the last time the page count was reset. The printer cannot register when a new photoconductor unit is installed, so it will not reset this page count automatically. Therefore, the messages continue — even after installing a new photoconductor unit.

In addition to the replacement error messages detailed above, the printer will stop printing if the photoconductor unit is not replaced and the page count manually reset. This occurs because the printer's page count reaches its terminal number of photoconductor roller revolutions independently of whether a new PC kit has been installed. The printer displays a Photoconductor Exhausted message at this point — again, whether or not the photoconductor is actually exhausted or not.          

To reset the photoconductor page count:

IMPORTANT! The photoconductor page count should be reset only when a completely new photoconductor unit is installed. Resetting the page count on the photoconductor unit, without replacing it, will cause the photoconductor to operate beyond its intended life. This will create various print quality issues, such as light print or streaks/spots on printed pages. The only exception to this would be in the rare case when a totally new printer displays this message right out of the box.

Step Action 1 Open the front cover. NOTE: Leave the printer powered on. 2 Press and hold the Stop/Cancel button for five seconds or until the message Resetting PC Counter appears on the printer display panel. 3 If done correctly, the printer will display Resetting PC Counter for a few seconds, then return to Close front door. The photoconductor page count should now be reset. 4 Close the front cover. See if the printer returns to the Ready status.   5 If the 84 Replace PC Kit/Replace Photoconductor message continues to occur after performing these steps, power off the printer. Wait ten seconds, then power on the printer again. If the error persists, please contact Lexmark Technical Support for additional information.
