• If the transparency colors are dull or dark, ensure the transparencies
meet the specifications for this printer (part number C2934A for
letter, and C2936A for A4).
• The selected colors are undesirable when printed. Select different
colors in your software application or printer driver.
• Spots and smudges appear in the background areas of
transparencies when they are projected. Oil from your hands can
cause spots or smudges on transparencies. Reprint, being careful
not to touch the surface of the transparencies.
• You are using a reflective overhead projector. Use a standard
overhead projector.
This might occur even though the correct media is loaded in the correct
tray. Toner might not adhere to the media and an image might show up
on pages where it isn’t meant to appear. (See “Full page ghosting” on
page 177.)
When this occurs on transparencies, the connections for the ITB
cleaning roller (clutch 3) and for the secondary transfer roller (clutch 4)
might be reversed.
Overhead transparencies that have repetitive defects spaced 131 mm
(5.2 in) apart indicate a defect on the upper fuser roller.
1 Turn the printer off and unplug the printer, allow 30 minutes for the
fuser to cool, and remove the fuser.
CAUTION
Make sure to allow 30 minutes before removing the fuser. The fuser
will be hot.
2 Turn the fuser gears and inspect the surface of the upper fusing
roller. If the roller has surface defects (gouges), replace the fusing
assembly.
