Multi-part binding		∙ Multi-part paper must be		bound at the top side by spot-gluing (Figure 1-
		12.).
		∙ The bindings must not be too hard. And there should not be any spilt
		glue.
		∙ The position of binding must be outside of printable area.
		∙ Multi-part paper should be bound firmly to each other and the binding
		must not be too large.
Perforation		Refer to Section 1.2.12.5.
Notes		∙ Overlapping multi-part form should be inserted from front entrance.
		Refer to Section 1.2.12.6.

∙Weak horizontal and vertical perforations cause paper jams.D

∙The length ratio of the cut part and uncut part of perforations must be more than 3 to 1 and less than 5 to 1 (Refer to Figure 1-13.).

∙Horizontal perforations must have an uncut part in each end of the paper (Refer to Figure 1-14.).

∙At the intersection of horizontal and vertical perforations, the cut part of the perforations must not cross each other (Refer to Figure 1-15.).

∙The raised part at the perforation must be less than 1 mm when the bottom layer kept by force (Refer to Figure 1-16.).

1.2.12.6 Notes

∙Clean paper (with no folds, creases, tears) should be used (Refer to Figure 1-17.).

∙The sprocket hole must be circular. The hole may have teeth (Refer to Figure 1-18.).

∙The sprocket hole of each layer must not be shifted (Refer to Figure 1-19.).

∙The litter of sprocket holes must be removed from the paper.

∙Paper should be fan-folded at horizontal perforations. Never use one that is not fan-folded property (Refer to Figure 1-20.).

∙No hole is acceptable in the printable area.

∙Paper must be torn off accurately along perforations.
