Note: Before printing envelopes, disable the duplexer if it is installed and
check the manual feed guides to make sure theyre not too tight and
buckling the envelopes. Also, make sure envelope size and type meet
specifications listed in appendix B, Technical Specifications, of your
Reference guide. If envelopes curl excessively, use the face-up output bin at
the rear of the printer.
The Optional Envelope Cassette
To load up to 100 envelopes at a time, use the optional envelope cas-
sette. Instructions for installation and use are in chapter 6, “Printer
Options,” in your
Reference
guide. See your QMS vendor for more
information on the optional envelope cassette.
Using Toner Cartridges
Quality printing requires uniform toner application and a clean paper
path. This chapter explains basic maintenance to keep your printer
running smoothly. It includes installing a toner cartridge, cleaning
printer parts, and general printer care.

displays. Usually, parts of the page print lighter. It is your option
whether or not to continue printing when the engine senses it is out of
toner.
When toner is low, it is sometimes helpful to take the cartridge out of
the printer and redistribute the toner. This is done by gently rocking
the cartridge side to side. Then reinstall the cartridge. If the

message remains in the display panel after redistributing toner,
