Troubleshooting
General problemsProblem / QuestionSolution / Answer
What do the blinking lights 
mean?See Understanding the control panel lights on page8 for information about what each 
light pattern means.
Why am I missing 
characters when I print on 
envelopes?If you see voids (missing characters) when printing envelopes, check your printer driver 
settings to make sure you selected Envelope from the Paper Type menu. 
If Envelope is already selected, try changing the texture setting to a rougher setting. 
Sometimes toner does not adhere well to smooth-textured envelopes. From your printer 
driver, select Custom6-RoughEnv from the Paper Type menu.
How do I clear a paper 
jam?See Clearing jams on page56 for information about clearing paper jams.
How do I restore the 
factory defaults?Sometimes restoring the printer to the original factory default settings solves formatting 
problems. To reset the factory defaults:
1Turn off the printer.
2Open the front door.
3Press Continue as you turn the printer back on. 
4Keep pressing Continue until the lights cycle, then release the Continue button.
5Close the front door.
6Press Cancel.
7Press Continue until the control panel cycles through all the lights.

The paper is curled once it 
exits the printer.•Use paper that is sealed in its original packaging.
•Turn the paper over.
•Rotate the paper 180 degrees.
•If you are printing a multiple-page job, try printing it duplex.
•When printing on heavy print media, open the rear exit door for a straight-through path.
•Try another kind or brand of print media, such as a xerographic paper for laser printers.
•If possible try printing in a less humid environment.
If the paper still curls, select the Reduce Curl setting from the Configuration menu (See 
Turning on Reduced Curl mode on page86.).
The toner low light 
sequence is on, but I don’t 
have another cartridge to 
put in yet. Can I still print 
with the low cartridge?Yes, you can still print. To extend the life of the toner cartridge somewhat, remove the toner 
cartridge, firmly shake it from side to side and front to back several times to use the remaining 
toner, then insert it back into the printer. Repeat this procedure multiple times. 
If print remains faded, replace the toner cartridge.
The printer seems to print 
slower when using the 
manual feeder.This is normal. The printer sometimes prints at a slightly slower speed when feeding print 
media from the manual feeder.
