Note Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography. Do not use raised letterhead. The printer 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 printer’s temperature (400° F or 205° C). Avoid using paper that has already been used in a printer or copier. Do not print on both sides of envelopes, transparencies, or labels. Paper Specifications 1-17
