Helpful Hints It is recommended that you test paper, especially special sizes and
types of paper, on the MFC before purchasing large quantities.
Avoid feeding labels with carrier sheets exposed, or your MFC will
be damaged.
Avoid using coated paper, such as vinyl coated paper.
Avoid using preprinted or highly textured paper.
For optimum printing, use a recommended type of paper, especially
plain paper and transparencies. For more information on paper
specifications, consult with your nearest authorized sales
representative or the place where you purchased your MFC.
Use label or transparencies that are designed for use in laser
printers.
We recommend you use long-grained paper for the best print
quality.
If you are using special paper, and the paper has problems feeding
from the multipurpose sheet feeder, try again using the manual feed
slot.
You can use recycled paper in this MFC.
