General Symptom List

Paper feeds poorly 1. Check the forms thickness lever: if it is set too tightly paper feeding can be affected. Set the forms
thickness lever to match the thickness of the paper being used.
2. Check for heavily tented horizontal perforations in the paper. If horizontal perforations are heavily
tented, consider setting the “Set Platen at BOF” configuration option (in the Printer Control menu) to
Open. (Refer to the
User’s Manual.)
3. Power off and unplug the printer. Remove paper. Inspect the paper feed path for obstructions that
could snag paper. Clear paper feed path of any obstructions.
4. Inspect the tractors and tractor door springs for damage, excessive wear, and equal door closing
tension. If either tractor is worn, damaged, or exhibits uneven door closing tension, replace both
tractor assemblies.
5. Check and adjust the paper feed timing belt. Replace the belt if it is damaged.
6. Check and adjust the platen gap.
7. Check the dynamic paper tension.
8. If the platen gap is correct, remove the shuttle frame assembly (page 362) and check the following:
a. Inspect the hammer bank cover assembly for ribbon debris, paper debris, or other foreign
matter. Make sure the four foam spacers on the ribbon mask are properly seated. If the ribbon
mask or hammer bank cover is damaged or deformed, replace it.
b. Inspect the paper ironer for distortion or misalignment. Reposition or replace it if necessary.
c. Make sure the paper guides are properly seated on the splined and support shafts.
d. Make sure the paper entrance guide pivots freely with minimal down force. Reposition the
springs or the guide if necessary.
e. Check for correct position and function of the paper motion detector assembly. Reposition or
replace if necessary.
f. Inspect the paper path from above (below the paper ironer), and from below (above the paper
entrance guide), for debris, foreign matter, or anything that could inhibit paper motion. Correct
as necessary.
