20 -Install the Spring Tension Adjuster in the
slot in the end of the Print Drum Axle.
21 -Install the Index Stop Pin & Washer.
22 -Tighten the Index Stop Pin using a 5/16”
hex wrench.
The tension adjuster should be pushed fully into the
axle slot.
ADJUSTING THE TENSION OF THE INDEX SPRING
The final step in the reassembly process is to adjust the tension of the Print Drum
Index Spring.
1 -Loosen only the top Print Drum Axle Retain-
ing Screw using a 9/64” hex wrench.
This screw should already be loose if you have just
replaced the Index Spring.
The Index Spring tension should be adjusted so the print drum returns in a smooth,
quick motion to the home or “indexed” position. Excessive tension will cause the
Print Drum to slam back hard against the Stop Pin and result in premature failure of
the Index Spring.

Rotate the Print Drum in a clockwise direction until
the arced slot in the Index Cam is directly below the
hole for the Stop Pin. Hold the Print Drum in position
while threading the Stop Pin into the hole.
