The 8R block is the long-running Xerox inkjet numbering, and this section covers it from 8R7659 through 8R7663, 8R7871, 8R7880, 8R7881, 8R7883 and 8R12591. The numbers run in sequence by generation rather than by color, so the full code matters when you order.
Solid Ink Sticks for Xerox ColorQube and Phaser
The 108R numbers are solid ink rather than liquid cartridges. 108R00926 cyan, 108R00927 magenta, 108R00928 yellow and 108R00929 black are supplied as two sticks per pack, with 108R00930 as a four-stick black and 108R00994 rated at 9k. Solid ink machines melt the stick on demand, so there is no cartridge to seat or prime.
