236 Chapter 11
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 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 ghosting of 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 is selected in the Mac OS or Windows
Page Setup dialog box.
