Problems with the Optional Envelope Feeder
Situation Solution
Envelope jams and 
envelope feeding 
problems.
! Make sure the envelopes are within the specifications 
listed on page 406
.
! Make sure the envelopes are properly loaded.
! Make sure the envelope weight on the feeder is down.
! Make sure the Optional Envelope Feeder extension is fully 
pulled out.
! Make sure that the fuser levers are properly set 
(page 128
).
Multiple envelopes feed 
into the printer.
The first (bottom) envelope to be fed must be closer to the 
pick up roller than the others.
No envelopes are fed 
into the printer.
! Make sure you are not overloading the envelope feeder.
! When loading the envelopes, be sure to push them all the 
way down to touch the rollers.
