MAINTENANCE
How can I clear paper jams? See Document Jams and Paper Jams, page 74.
Copy Quality Difficulties
Vertical streaks appear in
copies
Sometimes you may see vertical streaks on your copies. Either the
scanner or the primary corona wire for printing is dirty. Clean them
both.
Print Quality Difficulties
Printed pages are curled. Thin Paper (60-69 g/m
2
) can cause this problem. Make sure you
select the Paper Type that suits the paper in your paper tray. (See
Paper Type, page 18 and 22 and Media Type, page 32.)
Printed pages are smeared. Rough surfaces or thick media can cause “smeared pages”—OR—
“the toner to smear”. Make sure you select the correct Paper Type
that suits the paper in your paper tray. (See Paper Type, page 18 and
22 and Media Type, page 32.)
Printouts are too dark or light Adjust the print conditions by setting the Print Density function, it
has been factory set to the middle position. (See Setting the Print
Density, page 11.)
Printed pages contain white
stripes.
White Stripes or Faint Images
You may fix this by wiping the scanner windows with a clean soft
cloth. (See Regular Maintenance, page 81 and Cleaning the Printer,
page 82.) If you still see white stripes or faint images and the display
shows CHANGE DRUM SOON, replace the drum unit with a new
one.
Printed pages are stained with
toner or have vertical stripes.
Dark Stripes or Toner Stains
Clean the machine’s interior and the primary corona wire of drum
unit. (See Regular Maintenance, page 81 and Cleaning the Drum
Unit, page 83.) Make sure that the tab of the corona wire is at the
home position. If after cleaning, you still see dark stripes or toner
stains and the display shows CHANGE DRUM SOON, replace the
drum unit with a new one.
Printed pages have white
spots in black text and
graphic areas.
White Spots
Make sure that you use paper that meets the specifications. (See
Acceptable Paper, page 29.) Rough surface or thick media can
cause the problem. If you still see white spots and the display shows
CHANGE DRUM SOON, replace the drum unit with a new one.
Toner scatters and stains the
printed page.
Scattering Toner
Adjust the print conditions by setting the Print Density function.
(See Setting the Print Density, page 11.) Clean the machine’s
interior. (See Regular Maintenance, page 81 and Cleaning the
Drum Unit, page 83.) Make sure that you use paper that meets
specifications. (See Acceptable Paper, page 29.) If you still have
scattered toner and the display shows CHANGE DRUM SOON,
