Recommendation
Make sure that you use paper that meets our specifications. A rough surfaced
paper or thick print media can cause the problem. (See Acceptable paper and
other media on page 9.)
Make sure that you choose the proper media type in the printer driver or in the
machine's Paper Type menu setting. (See Acceptable paper and other media
on page 9 and Basic tab in the Software User's Guide on the CD-ROM.)
The problem may disappear by itself. Print multiple pages to clear this
problem, especially if the machine has not been used for a long time.
