Recycled Paper

In the past few years recycled paper has grown in popularity.
™
Constant testing of recycled paper for feeding on DocuMatch
systems is ongoing. Sometimes recycled paper lacks body,
which can cause problems in paper feeding. Use of recycled
paper may also cause problems with the opening of envelope
flaps and the insertion of mailpieces into envelopes. Conse-
quently, it is important to submit all samples of materials for
any application to your Pitney Bowes specialist for approval.

Paper Weights

An important specification to consider is paper weight. The
DocuMatch system has specific minimum and maximum
paper weights that can be processed. Staying within these
specifications will maximize the system's overall performance.
In the U.S., the weight is given in pounds for one ream (500
sheets) of a specific size of paper. For bond or copier paper
this specific size is 17 x 22 in. Since 8-1/2 x 11 in. paper is
one-fourth the size of 17 x 22, a ream of 20-pound bond
paper will weigh one-fourth of 20, or five pounds.
Other types of paper have different reference sizes. Offset or
book paper, often used for cut sheets in the DocuMatch, has
a reference size of 25 x 38 inches. Thus, 20-pound bond
paper corresponds to 50-pound offset paper.
Outside the U.S., paper weight is measured in grams per
2
square meter (gsm or g/m ). Twenty-pound bond paper
corresponds to 75 grams per square meter.
