3-96 Phaser 7300 Color Printer Service Manual
Random Bands, Lines, Marks or Spots
Random “missing” spots
There are areas of the image extremely light or
are missing entirely and do not appear to be a
repeating defect or in a single color.
■
This printer supports custom page sizes. When troubleshooting, print a test
print on at least letter size paper for diagnosing this problem. The problem
may be a repeating defect that is not noticeable on smaller media.
If the areas look like a repeating defect, see “Repeating (Defects) Bands,
Lines, Marks or Spots” on page 3-95.
■
Random missing spots can also be associated with “Cold Offset”, which
lifts toner off the page in certain areas. Usually this will occur in
high-coverage areas where the fuser temperature is not high enough to fuse
the toner on the media. This causes toner to be redeposited further down the
page. For Cold Offset, see "Cold Offset - Unfused Image or Image Easily
Rubs off the Paper" on page 3-100.
