Roll+Holder+Parts

=What are all the parts that ship with the roll holder spindle for?=

While the documentation is very poorly delivered (it doesn't have search capabilities), a thorough search of the documentation does include a full section on the spindle parts as well as the use of them, under the "Attaching Accessories to the Roll Holder" section.

The Borderless Spacer should only be used with ISO A2/A3 Rolls (420mm = 16.54") and not with 17" rolls (431.8mm width). When feeding a 17" roll of Crane Museo Rag and specifying in the CS2 plug-in that Borderless Printing was required, the printer refused to print with the spacer installed, and printed perfectly without it. The explanation that the spacer is for 16.54 inch (420 mm) paper would make some physical sense, because the spacer adds approximately (again, just visually - I haven't measured) the right thickness to push the edge of 16.54 inches to where 17 inches would be--allowing Canon to have only one overflow area.

Some additional information from Dan Wells on the Luminous Landscape discussion forum includes a great description of the remaining parts, including an explanation of the 1 and 2 labelled Holder Stoppers which are (as far as we know) totally undocumented:

"The spindle ships set up for 2 inch cores, and includes two blue adapters for 3 inch cores, which just snap into place. There is a borderless spacer fits right over the 3 inch adapter on the fixed end of the spindle. The last two pieces are grey end caps, marked, cryptically, "1" and "2". The "2" end cap turns out to be for heavy art paper. Hahnemuhle Photo Rag will not feed correctly without it. I don't know if Canon's 260 gsm satin (the other paper I have here) will feed correctly with the "2" cap - I used the "1" and it worked. I am going to try the satin with the "2" next time I switch rolls, so I don't have to keep swapping the 3 inch adapter between the "1" and "2" caps. The 3 inch adapter itself seems sturdy enough, but I worry about breaking the little "ears" that hold it into the cap if I keep swapping it back and forth."
