Film Waiting position is too far forward or
inconsistent.
- The leading edge of the film waiting to be fed into the
wrap area is too far forward - past the small hex shaft
that turns the Film Grab Paddles.
- Film is bunched up at the Film Separators.
1. The film is not adhering to the Polished Roller
a. Clean the Polished Roller with Isopropyl Alcohol and buff with a
clean, dry cloth.
b. Change film. The film is too oily to stick to the Polished Roller.
c. Change the Film Stop Position timing setting to stop the film
sooner. [Test menu, Wrapper Setup, page 2]
2. Replace missing Black Tape on the Film Separators. If the tape
is missing from the inner of the separator pairs it will not make
contact with the spring loaded small Green Belt assembly.
3. Check the Film Press small green belt assembly has free movement
up and down. Binding reduces the downward force required to
oppose the Film Separators.
4. Check the operation of the Film Counter Sensor. The counter timing
wheel and sensor are located on the front end of the large hex drive
shaft, below the front Film Feeder.
5. Confirm the Polished Roller does not turn when the brake is
engaged.
a. The Polished Roller Brake is not holding.
b. The Polished Roller outer sleeve has come loose from the inner
shaft.
6. Check the Cutter Brake. If the Cutter stops late the leading edge of
the next sheet will be too far forward.

1. Change film. The film is too oily to stick to the Polished Roller.
2. Film Feed Belts (white) are worn or contaminated.

Note
: if small film separates but not large
film this indicates worn belts.

is an additional 2-inch film strip.
- "Film Over" error may occur
- There may be abnormal noises
1. Check the Cutter "home" position sensor.
2. Check the Cutter "home" position sensor cable connections

that is part of the motor.
