Paper Type that suits the media type you use. (See Acceptable paper and other
media on page 2-1.)
Printed pages are smeared. The Paper Type setting may be incorrect for the type of print media you are
using—OR—The print media may be too thick or have a rough surface.
(See Acceptable paper and other media on page 2-1 and Basic tab in the Software
User’s Guide on the CD-ROM.)
Printouts are too light. If this problem occurs when making copies or printing received faxes, turn off
Toner Save mode in the machine’s menu settings. (See Toner Save on page 3-7.)
Set Toner Save mode to off in the Advanced tab in the printer driver.
