IBM 4230 - Model 4i3 B/W Dot-matrix Printer, User Manual, Page: 283 / 320

Weight
The basis weight for the paper should be 60 to 100 g/m ò (16 to 27
lb).
Composition
Plain bond paper of one of the following compositions should be
acceptable for regular use:
Ÿ
No. 1 sulphite (100% chemical wood pulp)
Ÿ
25% to 100% cotton content
Performance Considerations
For optimum performance:
Ÿ Use 75 to 80 g/m ò (20 to 24 lb), 25% or 50% cotton content
plain paper.
Ÿ Restrict printing to 6.35 mm (0.25 in.) from the left and right
margins and 6.35 mm (0.25 in.) from the top and bottom edges.
Ÿ Keep at least three sheets in the selected input bin (paper load
failure frequency increases otherwise).
All input bins are capable of handling multiple-part forms.
Multiple-part forms present special considerations because of their
complexity. There are many different types of multiple-part forms
available. Use only snap-out or top-glued multiple-part forms on the
ASF. Form sets should be operationally tested before regular use.
For specific information about multiple-part forms, see
IBM 4230
Printer Auto Sheet Feeder General Information.
Some forms such as highly embossed papers (many stock
certificates), coated papers, and multiple-part forms that do not
conform to specifications will not feed reliably by the ASF.
Forms are available from IBM or any forms supplier.
