How to prevent jamming and double-feeding during
batch mailing
By simple preventive measures and special care when positioning the stacks, you
can reduce feeding incidents and increase processing speed.
Selecting and preparing the mail pieces
Material and form of the mail pieces are of essential influence on the behavior during
feeding and separating from the stack. We have had good experiences with
processing envelopes of gray recycling material.
Thick letters (> 2 mm / 0.08")
Thin material (< 2 mm / 0.08")
Letter upper edges
Cards
• Arrange the letter stack so that all
envelope flaps are face down.
• Align upper edges flush:
Loosen letter stack with the upper edge
on a level base and shake smooth.
• Fan up the letter stack so that the lower
letter is the first protruding when
inserted in feeder.
Shortly press on the stack to remove any
air.
Fan the stack from all sides by waving
several times. Air can thus enter between
the mail pieces and paper dust will be
removed.
Leaf open the stack from all sides.
Sort out any cards which are too strongly
arched (arch > 4 mm / 0.15").
Sort out any cards with the front edge
arched upward.
