Print-Quality Troubleshooting
Smudges or Smears
Smudges or smears appear on the page. The likely cause is ink residue in the
media path. Check for residue on the rollers, Stripper Blade, guide ribs, or
inside the Preheater.
High coverage images with small margins may leave ink debris on the
Stripper Blade which is then re-deposited on other pages. This condition
usually self corrects (the debris is “cleaned” off the blade by lower coverage
images).

To avoid future problems, remind the customer to select "2nd Side" as the
paper type if manually printing duplex with preprinted solid ink images on
the reverse. This reduces Preheater temperatures to prevent partial
melting of the preprinted image.
Initial Actions
■ Check that the media used is supported.
■ Run the Remove Print Smears routine from the Control Panel.
■ Check the exit path for debris or contamination.
