I Have an mh 721
The blade holder wont move up or down, not even if I press the test cut or the origin button, I remove the carrige from the plotter and installed it on an other plotter that I have an mh 1351, and worked fine in that one, I cheked The cables That go from the carrige to The motherboard and they appear to be well soldered and complete, What do you suggest I do, I need this plotter because this one is the one I use for my shop office, the other one is on the location where I wrap Cars, any help will be appreciated.
Thank you.
