I have an Epson Surecolor P900 (SC-P900) with the roll media adapter. I am able to use it as expected, everything is coming out satisfactory, but I am having trouble cutting the paper in a straight line as it comes out. I have tried feeding it through a guillotine and roller cutter but it is extremely hard to fit the paper through it while still attached to the printer on the other end without scratching it. Using scissors works but is extremely difficult to cut straight. I have also tried using an exacto knife but similar issue with either risking scratching the print by using a ruler to guide the cut or making a crooked line.
What is recommended in this case? The manual does not offer a lot of guidance here and I haven't found a good reference for people using roll media in this printer.
