This Pinch Roller TD 1654 (B10) Type 2 is suitable for all Roland printers & cutting plotters. Each pinch roller is shipped with 2 washers. This pinch roller is suitable for the left and right sides of the machine. We recommend changing both P rollers on each side of the printer to avoid tracking problems. The pinch roller in the middle of the machine is a different part 6000003823 - 21565103. This part is the original Roland part (number 6000003824 replacing 21565102). These are the conical pinch rollers. Both rollers need to be replaced together. This 10mm wide pinch roller has an inner diameter of 4mm and an outer diameter of 15.6mm.
