Problem
(Dull or dark colors on
transparencies,
continued)
Rippled or wavy
transparencies
Cause and Solution
Verify that the printer is operating in an environment
consistent with the specifications listed appendix B.
You are using a transparency that is outside the
specifications for this printer. Use HP brand
transparencies to produce the best image quality for the
printer. For media specifications, see “Supported Media
Weights and Sizes for Input Trays” in chapter 3.
There is a wave or ripple in the background when
printing a solid color. Choose a background pattern that
uses less toner.
The paper path you are using might be rippling or
waving the page. Change the paper path by printing
from a different input tray to a different output bin.
Horizontal streaks on
transparencies
You are using a transparency that is outside the
specifications for this printer. Use HP brand
transparencies to produce the best image quality for the
printer. For media specifications, see “Supported Media
Weights and Sizes for Input Trays” in chapter 3.
Reflective overhead projectors reflect light through the
transparency twice, causing excessive light scattering
and producing colors that appear dark or dull on the
screen. If you are using a reflective overhead projector
(usually a portable overhead projector), use a standard
overhead projector, if available.
