Table 5. General Symptom List
1. Power off and unplug the printer. Remove the paper guide assembly or pedestal top cover. Make
sure connector P107/PAPR M is fully seated in connector J107 on the controller board. For -v20
models, check connector J103 on the controller board.
2. If the platen gap is correct, remove the shuttle frame assembly 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 and that their
lower ends are seated in the groove on the upper forward edge of the platen.
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.

paper moves correctly in both directions. Replace the paper feed motor if the message appears or

Open. (Refer to the User's Manual .)
