Other troubleshooting solutions may be found by visiting the Customer Forums or Technical Support Website, or by
calling the Technical Support Line (Web page addresses and Phone number on the specifications page, 34).
After a cut is made, you will need to reset the origin of the cutter.
If the origin is not set again, the first origin will remain in the
cutter and the cutter will return to this position before making any
further cuts. To reset the origin; from the main screen of the
cutter, press the Offline/Pause button on and then press the
Origin button.
and try again. Make sure that the blade can turn freely (by
attempting to turn it with your fingers while the release button of the Blade
Carriage is pressed).
Adjust the blade depth of the Blade Carriage (page 17) and Force
setting on the cutter (page 8) until you are getting solid, uniform
cuts. Start with a blade depth of around 1/64
pressure setting of 100g and try an increased pressure setting
before attempting to increase the blade depth.
If the blade is protruding too far from the Blade Carriage then it
can score and cut material during normal operations. If this is
occurring, the blade needs to be adjusted so that it is protruding a
minimal distance from the carriage. See the instructions on page 17.
Sometimes, during shipping or movement of the machine, the right
pinch roller will become stuck on a screw located on the back of
the machine. If this occurs and is affecting your cutting, press
forcefully against the pinch roller until it becomes dislodged from
its position. If needed, remove the screw to reposition the pinch
roller in the desired position.
Sometimes, during shipping or movement of the machine, the
Carriage Arm can be dislodged from its track. Make sure that the 2
white wheels behind the carriage arm are both resting securely on
top of (not in front) of the track. If the wheels are not on the track,
gently lift the carriage arm and press back until both wheels are
resting on the track.
