Perforations

Weak horizontal and vertical perforations may cause paper jams.


The ratio of the perforation length to the distance between perforations must be between 3 and 5. (See
Figure 1-13.)


Sheet edges must be uncut. (See Figure 1-14.)


Horizontal and vertical perforations must not cross. (See Figure 1-15.)


The perforation must be raised no more than 0.04 inch (1 mm) from the surrounding sheet surface. (See
Figure 1-16.)
Notes


Use clean paper with no folds, creases, or tears. (See Figure 1-17.)


The sprocket holes must be round. The holes may have teeth. (See Figure 1-18.)


The sprocket holes must be in the same location on each sheet. (See Figure 1-19.)


Punched out bits of paper must be removed before printing.


Paper should be fan-folded at horizontal perforations. Never use paper that is not fan-folded properly.
(See Figure 1-20.)


The printable area must be free of holes.
