Replacing the photoconductor kit

The printer automatically notifies you before the photoconductor kit reaches a page maximum by showing 84 PC Kit life warning or 84 Replace PC Kit on the display. You can also see the status of the photoconductor kit by printing a menu settings page.

When 84 PC Kit life warning or 84 Replace PC Kit first appears, you should immediately order a new photoconductor kit. While the printer may continue to function properly after the photoconductor kit has reached its official end-of-life, print quality significantly decreases.

Note: The photoconductor kit is one item only.
