Hi. I sent a job that I intended on printing, but unfortunately I had issues with the print due to the machine needing a cleaning. I held down the pause key to cancel it, and the machine said "Cancelling" like always. The problem is it was still trying to cancel... trying... trying... trying. Almost like it couldn't find the end of the file to cancel or whatever? I've had the SP300 forever, and unfortunately I'm not overly familiar with the best way to do things. After frustration, I just shut the thing off. I've cleared my rip log, unplugged the usb cable from the printer, just about everything imaginable? I put vinyl back in the machine, and sure enough it goes right back to heating up and wanting to print the job again! How do I get rid of this job? I apologize for not knowing... just this is driving me nut! Thanks
