Paper Handling Difficulties
The machine does not load paper. 
The LCD shows  No Paper Fed or 
Paper Jam . If there is no paper, load a new stack of paper into the paper tray. If there is paper 
in the paper tray, make sure it is straight. If the paper is curled, you should 
straighten it. Sometimes it is helpful to remove the paper, turn the stack over and 
put it back into the paper tray. Reduce the amount of paper in the paper tray, and 
then try again. Check that the manual feed mode is not selected in the printer 
driver. If the LCD shows 
Paper Jam and you still have a problem, see  Paper jams 
on page 6-4.
The machine does not feed paper 
from the manual feed slot. Reinsert the paper firmly, load one sheet at a time. Make sure that manual feed 
mode is selected in the printer driver.
How  can  I  load  envelopes? You can load envelopes from the manual feed slot. Your application software must  be set up to print the envelope size you are using. This is usually done in the Page 
Setup or Document Setup menu of your software. You should refer to the manual 
provided with your software application. 
What paper can I use? You can use plain paper, recycled paper, envelopes, transparencies and labels  that are made for laser machines. (For information on paper you can use, see 
About paper on page 1-6.)
How can I clear paper jams? See  Paper jams on page 6-4.
Print Quality Difficulties
Printed pages are curled. Low quality thin or thick paper can cause this problem. Make sure you select the  Paper Type that suits the media type you use. (See  About paper on page 1-6.)
Printed pages are smeared. The Paper Type setting may be incorrect for the type of print media you are  using—OR—The print media may be too thick or have a rough surface. 
(See  About paper  on page 1-6 and  Basic tab in the Software User’s Guide on the 
CD-ROM.)
Printouts are too light. If your machine is not connected to a computer, turn off Toner Save mode in the  machine’s menu setting. (See Toner Save on page 2-2.)
Set Toner Save mode to off in the Advanced tab in the printer driver. 
(See  Advanced tab  in the Software User’s Guide on the CD-ROM.)
If the printout is a copy, adjust the contrast. (See  Adjusting contrast on page 3-8.)

Cleaning the drum unit
Dust, paper powder, glue, and so on may stick to the surface of the photosensitive 
drum (OPC) and cause black or white spots to appear on printed documents.
Make a few copies of a blank, white sheet of paper. (See  Making multiple copies 
on page 3-1.)
1 Remove the drum unit and toner cartridge assembly, and then remove the toner  cartridge from the drum unit.
2 Position the print sample in front of the drum unit so you will know the exact  position on the drum that is causing the poor print.
3 Turn the black gear on the drum as you check the surface of the OPC drum. Do not touch the OPC drum with your fingers.
4 When you find the substance on the drum surface that matches the print  sample, gently  dab the surface of the OPC drum with a cotton swab that is lightly 
dampened with isopropyl alcohol.
Do not  use a scrubbing or wiping motion because this might damage the 
drum.
Do not try to clean the surface of the OPC drum with a sharp object, such as  a ball-point pen, because this might cause permanent damage to the drum 
unit.
If the print quality still has not improved you need to install a new drum.
