Hi Steve. I recently got a bn20 and I'm having trouble loading in custom sheet sizes. For example a 10 inch by 13 inch sheet. It loads the roll media fine. Sometimes it accepts the sheets, most of the time it says that it's in the wrong position. I can't see where the sensors are and what is the requirements for sheets. I called roland 3 times and their tech guys can't even answer this for me.. Would you happen to know?
