multiple-part forms are used, the forms can have different weights of
parts
(layers),

(4) Forms causing feed defects
The following forms are likely to cause feed defects, excluding those
described
before:
. Multiple-part forms with layers whose thickness or number varies by
section, such as shown in Figure 2.16.
Figure 2.16 Multi-part forms with layers of different thickness
. Multiple-part forms with layers glued in the print: area (Printing should
not be done on the glued portions.)
. Carbon paper which is covering pin feed holes of uultiple-part
(see Figure 2.17.)
Figure 2.17
. Self-adhesive label form with labels whose all sides are cut (see
Figure
2.18)
Such forms are likely to peel off.
label must be perforations to prevent peeling.
the weight of each part should be that given in
When forms are too thin, they will be damaged and a
