Pitney Bowes DM1000 User Manual

More than one enve-

lope is feeding.

Too many envelopes are on the 

feed deck; envelopes are not 

stacked properly on the feed deck.

•

Remove some of the envelope and test 

with a smaller stack. 

•

Slant the envelopes slightly to the left (shin-

gled). 

•

Put thinner envelopes on top of thicker 

envelopes in feeder.

Envelopes are too thick/thin for 

feeder adjustment, or thickness 

adjustment knob is set improperly.

Thickness adjustment knob is set 

too wide.

Adjust the thickness adjustment knob to corre-

spond to the envelope thickness. 

•

For thicker pieces of mail (3/8” to 5/8”), or 

mail containing several inserts, use the 

thick mail setting. For most mail under 3/8", 

use the normal mail settings.

•

For large stacks of thin mail, such as single 

inserts or post cards, the thin mail setting 

may be needed for better performance. .

Backstop is too close and is forc-

ing mail into the feeder.

Readjust backstop and restack mail.
