Technical information

Toner smudges appear on the front or back of the paper.
If stains appear on the paper, try the following steps.
m Ton e r s m udges may occur after a paper jam. In most cases, the printer
cleans itself after printing several letter-size pages.
m You may have previously printed using paper that was too small for the
printed document, which may have caused some toner to be deposited
inside the printer instead of on the paper. This can cause smudges on the
paper that goes through later. In most cases, the printer cleans itself after
printing several letter-size pages.
Faded areas or white voids appear on the page.
If portions of the page are faded or are missing, try the following steps:
m Use different paper or transparency material.
m Use paper that has been in a sealed wrapper; paper that has been out for a
long time may have too much moisture in it.
m Redistribute the toner in the cartridge (see “Replacing the Toner Cartridge”
in Chapter 10).
m Use the Apple Printer Utility for the Mac OS or the Apple LaserWriter
Utility for Windows to change the print density to a darker level (see
Appendix A).
m Replace the toner cartridge (see “Replacing the Toner Cartridge” in
Chapter 10).
Blotchy areas or ghost images appear on the page.
If there are blotchy areas within a gray area, or if you see ghost images
within printed areas (particularly on the top few inches of the page), try the
following step.
m Print two or three more copies of your page; these problems often occur
only on the first rotation of the photosensitive drum inside the printer.
The printer isn’t printing from the correct paper tray.
m Check that the correct page size and paper source are selected in the
Mac OS or Windows Page Setup dialog box.
