Photoconductor kit end-of-life
To ensure print quality and to avoid damage to the printer, the printer stops operating after the photoconductor kit has 
reached approximately 60,000 pages (Letter/A4). The message 84 Replace PC Unit is displayed when the printer 
reaches this point. If the Toner Alarm setting is set to Single or Continuous (default is Off), the printer automatically notifies 
you before the photoconductor reaches this point and displays the message 84 PC Unit Life Warning. To avoid having 
the printer stop operating, replace the photoconductor kit when you first receive the 84 PC Unit Life Warning message.  
Once the photoconductor kit has been replaced, normal printer operation resumes.
Conserving supplies
Several settings in your application software or on the display let you conserve toner and paper. For more information on 
changing these settings, see the Menus and Messages Guide.

							Clearing jams

8Clearing jams
By carefully selecting print media and loading it properly, you should be able to avoid most paper jams. For more 
information on avoiding paper jams, see Avoiding jams on page 47. If jams do occur, follow the steps outlined in this 
section.
To resolve the paper jam messages, you must clear the entire paper path and then press   to clear the message and 
resume printing. The printer prints a new copy of the page that jammed if Jam Recovery is set to On or Auto; however, the 
Auto setting does not guarantee the page will print.
Identifying jams
When the printer jams, the appropriate jam message appears on the printer operator panel. If you select Show Areas on 
the operator panel, you can view one or more images to help you clear the jam.

Clearing jams
Understanding jam messages
The following table lists the jam messages that can occur and the action necessary to clear the message. The jam 
message indicates the area where the jam occurred. However, it is best to clear the entire paper path to ensure you have 
cleared all possible jams.
Clearing printer jams
Although there are several places a jam can occur, clearing the paper path is fairly easy depending on the jam message or 
messages displayed on the operator panel.
Note:The following clearing jam instructions may seem out of sequence. However, they have been grouped 
to help you quickly clear the print path.
