I am relatively new to both this website and the industry. We purchased a small shop in Florida a few months ago after spending 15 years in the corporate world (different industry). With our shop we got a Roland SP540V which, outside some cutting issues, has served us well. Yesterday however, it stopped printing, the heads are moving and it acts like it is printing but, nothing. I have done a search here and reviewed the manual but don't see anything that seems to fit this problem. We have a call in to a service company but no call back to this point. Any suggestions as to where to begin trouble-shooting? Any help is appreciated!
