Print-quality problems
The following sections discuss print-quality problems that might be caused by print media.
Background toner particles
If the amount of background particles becomes unacceptable, the following procedures
might help to clear the condition:
● Increase the toner density setting. This decreases the amount of background particles.
● Change the paper to a lighter basis weight.
● Check the printer’s environment. Very dry (low humidity) conditions can increase the
amount of background particles.
Dropouts
If faded-out areas or character voids (partial print) occur randomly on the page:
● The moisture content of the paper might be uneven, or the paper might have moist
spots on its surface as a result of environmental humidity. Store the paper in a
moisture-proof container. Try removing the top few sheets of paper from the paper tray
or use paper from a different source (such as another ream), or try a different brand of
paper.
● The paper lot is bad. The manufacturing processes can cause some areas to reject
toner. Try a different kind or brand of paper.
Improperly formed or wavy characters
If characters are improperly formed or if the printer is producing hollow images, the paper
stock might be too smooth. Try a different paper if characters are improperly formed.
Toner smear
● If toner smears appear on the leading edge of the paper, the paper stock might be too
slick. Try a different paper if the toner is smearing on the paper.
● If toner is not fusing properly (and is smearing), try a higher fuser mode setting (if
available). For more information, see the support documentation that came with your
printer.
Toner specks (background scatter)
Toner speaks are black dots that appear randomly on either side of the page. If the toner
specks appear, the media might not meet the specifications for your printer (for example,
the paper is too moist or too rough). For more information, see the support documentation
that came with your printer.
