Make sure that you use paper or OHP films that meet specifications and
have the correct printing surface.

Toner Scatter
If toner scatters around printed characters and stains the printed page,
clean the printer interior. See
Fig. 7-13 Toner Scatter
If the same print problem occurs after cleaning, take any of the following
actions:
• Make sure that you use paper, OHP films, or envelopes that meet
specifications.
• Check for glue on the paper. Glue causes toner to scatter.
• If toner scatters over the entire printing surface, adjust the print
density. See "Checking the Printed Test Pattern or Font List" in
Chapter 2.
"Cleaning" in Chapter 6.
