Lexmark 302 - Manual (Page 231)

Problem: Forms do not stack correctly
1: The forms do not stack correctly on the table behind the printer.
Solution: Use the recommended table (see IBM 4232 Printer
Model 302 Planning and Site Preparation Guide).
Note: Up to 101.6 mm (4 in.) of forms may stack on the table
behind the printer without decreasing the ability of the forms to
stack correctly.
2: The forms do not stack correctly in the output rack on the table.
Solution: Check for obstructions to the paper path (cables,
cords, or other items). If you find an obstruction, remove or
relocate it.
3: The forms are specified incorrectly.
Solution: The forms may be outside nominal specifications. See
Appendix C, “Forms Information.”
4: The forms contain excessive moisture.
Solution: Store the forms in a cool, dry place before using them
or leave in the printer for 24 hours.
Note: Forms stack best when the forms are 203.2 to 304.8 mm
(8 to 12 in.) long. If the forms length is outside this range,
operator aid may be needed.
Problem: Erratic or intermittent forms movement
1: The forms device is defective or the printer is failing.
Solution: See “Forms Device Inspection” on page B-24.
