Problem: No cutter signal.
ACTION: Check cutter cable connections and conditions. May need to
replace Prodigy Plus
TM
Board.
Problem: No solenoid reset (clicking) on turning switch ON.
Probable Cause: Transformer is bad or there is a bad cable.
ACTION: Check the input voltage from voltage regulator to applicator
board. It should read 0, 5, 25, 0 (white, green, red, black). If the
green lead is below 5V, check the voltage across the blue to blue
and red to red on the Prodigy J5 plug. It should read 8.5+ volts
on each side. If it doesn’t read that, the transformer is bad.
Unplug all the prodigy cables except J5, J9, J6 and J7 from the
rectifier block. Replug one at a time while checking the 5 volt
lead on J3. A bad cable will cause a voltage drop, replace the
cable.
Problem: Ribbon and Label won’t back up after each label prints.
Probable Cause: Label drive roller gear set screw is stripped.
ACTION: Replace set screw.
Problem: Edge sensor voltage of 5V will not adjust.
Probable Cause: Edge sensor or applicator board is bad.
ACTION: Pull edge sensor plug J2. If the voltage drops replace the edge
sensor. If the voltage remains the same, replace the applicator
board.
Problem: Label is only printing on one or more lines or part of lines.
Probable Cause: Printhead is bad.
ACTION: Check printhead cable. If it is ok, replace the printhead.
