Remanufacturing the HP CP1215

First released in April 2008, the CP1215 series of color laser printers is based on a 12-ppm (black), 8-ppm (color), 600-dpi engine. (2,400 dpi with RET in the CP1215 and up to 3,600 dpi with RET in the CP 1518ni/CM 1312nfi MFP.) The 1215 cartridges are an all-in-one-type cartridge that consists of the toner supply, drum and waste chamber. Like the CLJ-2600 these machines use an in-line, or single-pass system. The difference here is that all four cartridges are stacked in line, front to back, instead of on top of each other as in the 2600. See Figures A and B.
Because of this new machine layout, we will take a moment and run through the printer theory before we get started. The cartridge itself looks different from any previous Canon/HP cartridges I have seen. It’s basically a rectangular-shaped cartridge that comes with a toner seal and a snap-on drum cover across the bottom to protect the drum. See Figures 1 and 1A. New machines ship with starter cartridges rated for 750 pages so users will run out of toner fairly quickly.
These cartridges can be disassembled fairly easily. Unlike the CLJ 2600, no cutting of the drum or cutting of any kind is necessary. There is a small problem removing the feed roller and thus filling the cartridge, but nothing too problematic. That will be explained later in the instructions.
