We have a XC-540 with very low hours. It prints great and cuts great but the media will walk about a 1/4+" every 2.5hours. We have brand new media flanges however we dont have the locks. Also I feel the pinch rollers are in great shape... We are still fairly new in the vinyl printing industry. Is this the norm? We are running long production runs print/cut and would like to make it as low maintenance as possible.
