Print quality difficulties
Difficulties Suggestions
Printed pages are curled. „ Low quality thin or thick paper or not printing on the recommended side of the
paper could cause this problem. Try turning over the stack of paper in the
paper tray.
„ Make sure that you choose the Paper Type that suits the print media type you
are using. (See Acceptable paper and other print media on page 11.)
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 print media on page 11 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, set Toner Save mode
to off in the machine menu settings. (See Toner Save on page 19.)
„ 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.)
