I am sorry, and I am sure I should know this. I purchased by machine used and it works well but I have contacted Roland twice and have gotten the same answer both times but it really has not answered what I need. I am being told I can use any width roll up to 30inches. My problem is I get some rolls that are 20 inches so when I load them if I don't put the pinch roller on the roller that is on the bed of the machine then I get the pinch roll error. This makes a 20in roll only have a usable area of about 13 inches. Am I missing something or is this just the way it is? I hate wasting that amount. Do I have a sensor or something bad or do the pinch rollers have to be on the bed rollers to work, if so then I can't just use any width up to 30 inches. Thank you for your assistance. SJ
