Using Print Materials
Properly storing the paper you buy helps ensure trouble-free
printing. Use the following guidelines:
•
For best results, store paper in an environment where the
temperature is approximately 21
humidity is 40%.
•
Store cartons of paper on a pallet or shelf, rather than
directly on the floor.
•
If you store individual packages of paper out of the original
carton, make sure they rest on a flat surface so the edges do
not buckle or curl.
•
Do not place anything on top of the paper packages.
For optimum printing on envelopes, use only new, undamaged
envelopes. When you print on envelopes, the glue must not be
exposed. The combination of high humidity (over 60%) and the
high printing temperatures may seal the envelopes.
When printing on envelopes, be sure to select Env Feeder or
MP Feeder as the paper source and set the correct envelope size.
The laser printing process heats envelopes to a temperature of
o o
200 C (392 F). Use only envelopes that are able to withstand these
temperatures without sealing, excessive curling, wrinkling, or
releasing hazardous emissions. If you have any doubts about the
envelopes you are considering using, check with the envelope
supplier.
For best performance, use envelopes made from 75 g/m
