Today I tried  cutting  something and I loaded media and the liver didn't respond on my graphtec FC 70O0-75

 I opened it up and cleaned the sensor in hopes of  it responding but no luck . Is this machine done or is it still fixable ?

"lever" ----  I don't own a Graphtec, but apparently what you are saying is that the pressure rollers are controlled by a single lever and the main control board will recognize the lever being put in the Down (closed) position, and automatically Poll the media (determine width of vinyl). Your machine is failing to do that, right?

Fixing a problem like this might indeed require a replacement of the sensor itself.

had something like that on a roland gx-24 once - after playing with it I finally let the lever snap back on it's own and it jarred the micro switch enough it worked normally

Well, there is a sensor that detects when the lever is up or down, you would need to remove the plastic cover nearest the control panel side of the machine to get to it. This may or may not be the culprit.

Make sure the white connector is plugged in to the sensor. I suppose the sensor could fail but I don't think it would be unlikely since there are no moving parts on the sensor itself.

 

Also, I suppose you could try a  factory reset by holding the arrow up button while turning on the cutter.

Another thing, were you trying to cut too small of a piece of vinyl? The vinyl has to cover the rear sensor of the cutter or it won't allow the cutter to proceed.

Something else you might try is turning off the sensors in the cutter setup menu.

I found it it was the cam sensor.  We took it apart and found out it was chipped from a corner. I called Graphtec of America and they said they no longer carrie a discontinued part. All it needs is this small sensor 'but now I'm out of luck.:/ Thanks everyone . Love this forum .
