6.5 Feed Assembly Adjustment
Feed Assembly adjustment is set at factory to track tape straight from last print
station through knife and nip assemblies. Various circumstances can occur and
result in stock tracking toward or away from printer causing jams. To adjust tape
tracking follow these steps:
1. Start printing either a loaded batch or use test patterns as described in
section 3.4.1. When printer begins printing apply slight resistance to unwind
media (placing slight pressure with palm of hand to media is sufficient),
making it harder for feed to pull material through machine.
a. If material begins tracking correctly adjust unwind tension higher
following steps in section 8.1. Once in printer setting click tab for
“Arbor Tension”, then adjust “Stock Arbor” from “Nominal to
Higher” a little at a time. Clear batch and retry until tape tracks
correctly.
b. If material continues tracking abnormally after testing with slight
palm pressure do not adjust tension mentioned in 6.5.1a and
continue with step 6.5.2.
2. Check for missing, bound, or crushed auxiliary roller springs, damaged
auxiliary rollers, or material that does not belong in feed assembly. If
anything abnormal is present replace parts, if foreign objects are present,
remove and retest to see if these were the cause.
3. If there are no mechanical issues adjust Feed Assembly alignment by
backing out adjustment set screws shown in figure 20a using a 5/32 Allen
wrench until they stop on Feed Assembly frame. Note this only needs to be
done until screws touch assembly, too much force will bend assembly frame.

4. Loosen 3 Phillips head screws holding Feed Assembly to machine.
