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 

or

as the paper 

source and set the correct envelope size.

The laser printing process heats envelopes to a temperature of 
200

o

C (392

o

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.
