Envelope guidelines

When printing on envelopes:

• Use only new, undamaged envelopes.

• Make sure the glue is not exposed.

• Remember that a combination of high humidity (over 60%)

and the high printing temperatures may seal the 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

200

C (392

F). Use only envelopes that are able to withstand these

temperatures without sealing, excessive curling, wrinkling, or releas-

ing hazardous emissions. If you have any doubts about the enve-

lopes you are considering using, check with the envelope supplier.

For best performance, use envelopes made from 75 g/m

(20 lb

bond) paper. You can use up to 105 g/m

(28 lb bond) weight for the

multipurpose feeder or 105 g/m

(28 lb bond) weight for the enve-

lope feeder as long as the cotton content is 25% or less. Envelopes

with 100% cotton content must not exceed 90 g/m

(24 lb bond)

weight.
