printer may not give satisfactory results.
• If you are getting streaks or spots on your prints, the OPC
drum on your printer may need to be cleaned.

Character voids • The paper may be too dry. Try printing with a different
batch of paper.
Background scatter • The paper may be too damp. Try printing with a different
batch of paper. Do not open packages of paper until
necessary so that the paper does not absorb too much
moisture from the air.
• Printing over uneven surfaces. If printing onto envelopes,
change your printing layout to avoid printing over areas
that have overlapping seams on the reverse side.
