Print Quality
!
Caution
You may clear a print quality problem by replacing the drum unit with a
new one if the
Drum
lamp is on. The drum unit is at the end of its life.
Question Recommendation
Printouts are too dark or light. Turn the print density dial counterclockwise for
lighter images and clockwise for darker images. It has
been factory set to the middle position. See
“ADJUSTING THE PRINT DENSITY”
in Chapter 5.
Printed pages contain white
stripes.

You may clear the problem by wiping the scanner
windows with a soft cloth. (See
“Cleaning the printer
interior and Drum unit.”
in Chapter 5.)
If you still have the same problem and the
Drum
lamp is on after cleaning, replace the drum unit with a
new one.
Printed pages are stained with
toner or have vertical stripes.

Clean the printer interior and the primary corona
wire of the toner cartridge. See
“Cleaning the
Printer Interior and Drum Unit”
in Chapter 5.
Make sure that the tab of the corona wire is at the
home position.
If you still have the same problem and the
Drum
lamp is on after cleaning, replace the drum unit with a
new one.
Printed pages have white spots
in black text and graphics area.
Fig. 6-10 White Spots
Make sure that you use paper that meets the
specifications. Rough surface or thick media can
cause the problem.
If you still have the same problem and the
Drum
lamp is on, replace the drum unit with a new one.
