General problems

Problem / Question
What do the blinking lights
mean?
Why am I missing
characters when I print on
envelopes?
How do I clear a paper
jam?
How do I restore the
factory defaults?
The paper is curled once it
exits the printer.
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?
The printer seems to print
slower when using the
manual feeder.
Envelopes jam when
printing with the rear exit
door open.
Solution / Answer
See Understanding the control panel lights on page 8 for information about what each
light pattern means.
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 Custom 6-Rough Env from the Paper Type menu.
See Clearing jams on page 56 for information about clearing paper jams.
Sometimes restoring the printer to the original factory default settings solves formatting
problems. To reset the factory defaults:
1 Turn off the printer.
2 Open the front door.
3 Press Continue as you turn the printer back on.
4 Keep pressing Continue until the lights cycle, then release the Continue button.
5 Close the front door.
6 Press Cancel.
7 Press Continue until the control panel cycles through all the lights.
The Load Paper, Toner Low / Replace PC Kit, Ready and Continue lights appear.
8 Release the Continue button.
9 Turn the printer off and back on.
Factory defaults have been reset.
• 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 page 86.).
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.
This is normal. The printer sometimes prints at a slightly slower speed when feeding print
media from the manual feeder.
Close the rear exit door.
