Our Gerber HS15 suddenly started working incorrectly. It only cuts the first label and then quits. It seems to think it is finished with the job even though there is a page full of labels left to print. Has anyone run into this before? We thought maybe it was something weird in the job file so we tried old jobs (that have worked in the past) and the same thing happens. Any ideas? Someone told me it probably needs a new motherboard. Are those still available?
