Print Quality Difficulties
Printed pages are curled. Low quality thin or thick paper can cause this problem. Make sure you select the
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 3-5.)
Set Toner Save mode to off in the Advanced tab in the printer driver. (See
Advanced tab in the Software User’s Guide on the CD-ROM.)
Network Difficulties
