Check to see if the CHECK PAPER or PAPER JAM message appears
on the LCD. If so, the Multi-purpose Sheet Feeder may be out of paper
or not properly installed. If it is empty, load a new stack of paper into the
feeder and then press Fax Start. If there is paper in the Multi-purpose
Sheet Feeder, 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 Multi-purpose Sheet Feeder. Reduce the
amount of paper in the Multi-purpose Sheet Feeder, then try again.
Sometimes you may see vertical streaks on your copies. Either the
scanner or the primary corona wire for printing is dirty. Clean them both.
Thin Paper (64-69 gsm) can cause this problem. Make sure you
select the Paper Type that suits the paper in your multi-purpose
sheet feeder. (See Paper Type, page 51 and Media Type, page 59.)
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 multi-purpose sheet feeder. (See Paper
Type, page 51 and Media Type, page 59.)
has been factory set to the middle position. (See Setting the Print
Density, page 22.)
You may fix this by wiping the scanner windows with a clean soft
cloth. (See Regular Maintenance, page 120 and Cleaning the Drum
Unit, page 122.) If you still see white stripes or faint images and the
display shows CHANGE DRUM SOON, replace the drum unit
with a new one.
Clean the machine's interior and the primary corona wire of drum
unit cartridge. (See Regular Maintenance, page 120 and Cleaning
the Drum Unit, page 122.) 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.
Make sure that you use paper that meets the specifications. (See
Acceptable Paper, page 56.) 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.
