Troubleshooting > 70

Your printer has been designed to give you helpful status feedback not only during normal 

operation but also if a printing problem occurs so that you can take appropriate corrective 

action.
The LCD on the printer operator panel provides the self-explanatory status and error 

messages in your chosen language. Error messages are accompanied by the Ready 

indicator being extinguished.

Provided that you follow the recommendations in this guide on use of print media, and you 

keep the media in good condition prior to use, your printer should give years of reliable 

service. However, paper jams occasionally do occur, and this section explains how to clear 

them quickly and simply.
Jams can occur due to paper misfeeding from a paper tray or at any point on the paper 

path through the printer. When a jam occurs, the printer immediately stops, and the 

operator panel informs you of the event. If printing multiple pages (or copies), do not 

assume that having cleared an obvious sheet that others will not also be stopped 

somewhere along the path. These must also be removed in order to clear the jam fully and 

restore normal operation.
The printer may experience a paper jam in one of three areas. 

INPUT JAM - paper has failed to leave the selected feed tray and enter the internal 

paper path of the printer. A typical message indicates a paper jam and identifies the 

tray to check.

FEED JAM - paper has entered the printer but failed to reach the exit. A typical 

message indicates a paper jam and advises you to open the top cover for access.

EXIT JAM - paper has reached the exit but has failed to exit completely from the 

printer. A typical message indicates an exit jam and advises you to open the top 

cover for access.
