Paper jams and how to clear them
If paper jams inside the printer, the printer will stop. One of the following LCD messages will appear to 
tell you where to find the jammed paper.
Figure 6-1
Paper may jam in the paper tray, inside the printer, at the back cover, or where the paper comes out of 
the printer. Check where the jam is and follow the instructions on the next few pages to remove the 
jammed paper.
If the error message still appears on the LCD after you remove the jammed paper, there may be more 
paper jammed somewhere else. Please check the printer thoroughly.
After you have followed the instructions, the printer will resume printing automatically. However, the 
Status LED may come on and the following message may appear on the display:
After a paper jam has occurred, data usually stays in the printer memory. The message prompts you to 
do a form feed to print the data that is left. Press 
Go to continue. Paper jam in the standard paper tray (TRAY1)
Paper jam in the optional lower tray (TRAY2)
Paper jam at the entrance to the fusing roller.
Paper jam where the paper comes out of the printer.
