Problem
Probable Cause
Corrective Action
Cracks or craze marks
appear on face of
finished labels.
1) Incorrect adjustment of decurler.
1) Move decurler turn-bar toward unwind end of
machine until cracks no longer appear.
Stock jams in bridge blade
rollers or knife area.
1) Knife mounted bridge blade too
close to stationary bridge blade.
1) Loosen screws in upper knife securing bridge
blade roller assembly and slide up (holes in
blade are slotted) until rollers just contact stock.
Tighten screws.
2) Knife not cutting full width of
stock.
2) Loosen knife shear adjustment screws and
move outer end of knife until full cut is
accomplished.
3) Stacker not operating or nip
rollers not turning.
3) Check stacker connection to access port. Be
sure nip roller is free to rotate and moves easily
in the bearing slots.
Will not stack.
1) Stacker not operating.
1) See step 3 above.
2) Stacker position on machine too
far forward so labels go under
rear stacker rail.
2) Loosen stacker mounting knob and move
stacker toward rear of machine - tighten.
3) Incorrect rail position or stacker
bed angle.
3) Using a cut label, position stacker rails so that
approximately 3/8" (9.5mm) overhangs the
second grooved roller. Loosen quick-turn
handle on stacker clamp and raise or lower
stacker bed until opening between 1st label
overhang and belt surface will allow entry of
next label.
Knife will not cut or partial
cut
1) Incorrect pre-load on clutch pawl.
1) With back cover removed and power off -
operate solenoid by hand. When lever is
moved, clutch pawl should move counter-
clockwise about 1/32" (0.79mm) with the "pac-
man" in home position. If not - loosen "pac-
man" set screws and readjust "pac-man" to stop
with spring in detent.
2) Partial cut
2) Loosen shear adjustment screws and move
outer end of knife until full cut is obtained.
