I'm new to the cutting end of graphics, I just purchased an older roland pnc 1410 from craigslist. In going over the machine I notice it needs to have 2 of the sheet loading levers replaced as they have been snapped off. These being for the pinch rollers to raise and lower the rollers. I cannot find a source for replacement parts like these so far on the internet. Does anyone have a good source for finding parts on older roland equipment? Thanks in advance. This is a great site btw.
