 Make sure that the media type setting in the printer driver matches the type
of paper you are using (see Acceptable paper and other print media
on page 2).

cause hollow print (See the Product Safety Guide).
 If the problem is not solved after printing a few pages, the drum may have
foreign material, such as glue from a label, stuck on the drum surface. Clean
the drum unit (see Cleaning the drum unit on page 163).
