2.5.3 Multiple-part forms
This printer utilizes up to 6-part forms. Interleaved carbon paper utilizes
6-part forms and is not included in the number of parts. Forms with
interleaved carbon paper, carbon-backed forms, and forms using carbonless copy
paper are available as multiple-part forms. Each part of multiple-part forms
must meet the specifications in Subsections 2.5.1 and
2.5'.2.
They must be of
the same length and width.
This section describes the fastening, misalignment, and thickness of
multiple-part forms and also how multiple-part forms cause feed defects.
(1) Fastening multiple-parts
Each part of multiple-part forms must be fastened together at one or both
pin feed hole areas by gluing or crimping. Multiple-part forms with
interleaved carbon paper should be fastened on the right.
Staples
must
not be used on forms.
If they are used,
the printer print section will be
damaged and a feed error will occur.
For gluing, do the following:
. The shape of glued parts should be dots or stripes in the vertical
direction, as shown in Figure 2.14,
. Glue should be applied evenly and must not cause wrinkles or discolor
the paper.
. Do not apply glue to the perforations. If stripe gluing is necessary,
the glue must not
ooze
through perforations of the top and bottom
layers.
. Glue cannot be used if forms lose pliability.

Figure 2.14 Methods of fastening paper
For crimping, do the following:
. Layers must be firmly fastened and must not come
:Loose.
. There should be no paper tailings or dust.
. Forms should maintain their shape so as not to cause jams.
. Crimps must not overlap horizontal perforations. If crimps overlap
horizontal perforations, the forms will tear at
t:he
perforation.
. Crimps should not project through the bottom
shee,t.
If layers of multiple-part forms are not properly
f,astened,
the layers are
likely to peel apart, causing feed defects.
