Guidelines for using paper
For best results, use conventional 75 g/m
2
(20 lb bond) paper. Make sure the paper is of good
quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or
bent edges.
If you are unsure what type of paper you are loading (such as bond or recycled), check the label
on the package of paper.
Some paper causes print quality problems, jamming, or damage to the MFP. Do not use
letterhead paper that is printed with low-temperature inks, such as those used in some types of
thermography, and do not use raised letterhead. Coated papers and some transparencies can
wrap around the fuser roller and possibly cause jams.
The MFP uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or
preprinted forms use inks that are compatible with the MFP fusing temperature (200°C or 392°F
for 0.1 second).
