Problem: Forms do not stack correctly
1: The forms do not stack correctly on the table behind the printer.
Solution: Use the recommended table size (see Appendix A, “Printer
Specifications”).
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. For additional
information on stacking, see “Forms Stack Input and Output Locations” on
page 19-4.
3: The forms do not meet IBM specifications.
Solution: The forms may be outside nominal specifications. See Chapter 19,
“Supplies, Optional Features, and Maintenance.”
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 assistance may be
needed.
5: Forms are too dry.
Solution: Condition the forms for 24 hours or more at the manufacturer
recommended temperature and humidity settings.
Problem: Characters are off registration
1: The first print position is adjusted incorrectly.
Solution: Check your settings for the left margin, tear position, and the paper
load position. See Chapter 11, “Printer Adjustments” for information on
adjusting these settings.
2: Left tractor or cut-sheet feed alignment guide not set to left alignment mark.
Solution: Set the left tractor to the left tractor alignment mark or set the left
cut-sheet feed alignment guide to the alignment mark.
Problem: Manual cut-sheet form does not overlay continuous form properly
1: The form is skewed into the printer or doesn't feed into the printer at all.
Solution: Hold the cut-sheet form firmly in place until the form is fed into the
printer.
