Speciality Forms
Specifications
This section of paper specifications is intended to familiarize and
alert the user to some of the characteristics of specialty forms which
may cause unsatisfactoiy performance of the printer. This paper
specification is NOT intended as a substitute for actual testing.
Note
All specially forms, including special single-part paper, multi-part forms,
forms with glue strips, carbonless forms, card stock, and labels should
be tested for satisfactory feeding, registration, and print quality prior to
purchase.
Form Thickness
Uniformity
Because of the small print gap in dot-matrix printers, these printers
are less tolerant of form thickness variations than are full-font printers.
Sometimes these thickness variations can he caused by defects such
as hubbies or wrinkles. Other times they are due to varying paper
composition or the number of parts within the form.
Nominal differences in thickness and compressibility make it impossible
to specify allowable thickness variations exactly. The following cases are
intended to serve as a guide, but all forms width thickness variations
must be tested for satisfactory performance.
Case 1: Form Defect
In order to avoid hammer dragging, the overall thickness of a form plus
any defects should be no more than as shown in Figure B-1 (.015-t-T/2;
T=thickness) inch.
