The HP Designjet Z6 Pro has two roll attachment points. Unlike our previous plotter, it does not make use of spindles. Loading and unloading the paper is done with bare rolls slotted on to the appropriate end attachments, one of which is fixed on the right side of the plotter and the other is adjustable to accommodate different sized rolls. We will use Roll 1 (the top roll) for 36" semi-gloss paper and Roll 2 (the bottom roll) for 36" canvas paper. When swapping back and forth with our 60" rolls, please be sure to put semi-gloss on Roll 1 and canvas on Roll 2 for consistency. When loading a fresh roll, please make sure to manually input the paper length so that we can avoid running out of paper mid-print. The 36" rolls and 60" semi-gloss roll are 100 ft long, and the 60" canvas roll is 60 ft long.
