Recommendation

Make sure the media type setting in the driver matches the
type of paper you are using (see Acceptable paper and other
print media on page 29).

Check the machine's environment. Conditions such as high
humidity can cause hollow print
(see Product Safety Guide: Choosing a location).

If the problem is not solved after printing a few pages,
foreign material, such as glue from a label, may be stuck on
the drum surface (see Advanced User's Guide: Cleaning the
drum unit).

Identify the color causing the problem and install a new drum
unit (see Replacing the drum units on page 83).
