Problem
Print is faint or
uneven (continued).
Printing on envelopes
is either faint or too
dark.
The characters are
blurred.
Solution
The envelope lever is in the wrong
position. When you print on envelopes,
move the envelope lever to the envelope
position.
The envelope is too thin or too thick. Use
only envelopes that fall within the range
specified in Chapter 7.
You may not be using the correct type of
paper. Make sure the surface of your
paper is not too rough or too smooth.
Although most types of business
correspondence quality paper work well
with your printer, always test the paper
you want to use before buying it in large
quantities.
You may not be printing on the correct
side of your paper. Test the other side to
determine which side gives the best
quality.
The paper is oily, dirty, or wrinkled. Use
only clean, new paper.
