Troubleshooting

Too much paper loaded.

Make sure that the paper stack does not exceed the paper load limit. However, 
proper feeding of paper may not be possible at this maximum capacity 
depending on the type of paper or environmental conditions (either very high or 
low temperature and humidity).
In such cases, reduce the sheets of paper you load at a time to around half of 
the paper load limit.
For details on loading paper, see “Loading Paper” on page 26.

Foreign object in the Rear Tray or 
Cassette.

Make sure that there are no foreign objects in the Rear Tray or Cassette.

Envelopes not prepared or loaded 
properly.

When printing on envelopes, load them in the machine in portrait orientation. If 
the envelopes are placed in landscape orientation, they will not feed properly.
For details on loading envelopes, see “Loading Envelopes” on page 30.

Inner Cover is not completely closed.

Close the Inner Cover completely. Paper does not feed properly if the Inner 
Cover is even slightly open.

The paper source is specified in the 
data created by an application 
software.

When the paper source setting is inconsistent between an application program 
and the printer driver, the application software setting takes precedence.
Change the application software setting corresponding to the printer driver 
setting, or click Print Options on the Page Setup sheet in the printer driver and 
select Disable the paper source setting of the application software on the 
Print Options screen.
For the print option setting, refer to the PC Printing Guide on-screen manual.
