Remanufacturing the Canon “P” Type Toner Cartridges
0343

Overview

Released in February 2004, the Canon ImageClass 2300 printer engine is based on a new 20ppm, 1200 DPI laser engine. The style of this cartridge is a departure for Canon against the “normal” style cartridge we have become used to. This cartridge is actually somewhat similar to the 4600, but much simpler. The cartridge is rated for 10,000 pages at 5% coverage. The “P” cartridge is built to last. In comparison to some of the other new Canon cartridge to date, the parts in these cartridges seem very durable. Even the plastic is thicker than normal these days. At this point, the wiper blade, PCR and drum will last at least one cycle. That may change as time goes on though.

The “P” cartridge does not have an internal drum cover. It comes with a large orange plastic cover that snaps over the drum section. It is highly recommended that these covers be installed to prevent any drum damage. See Figure 1

How to run test pages, Printer trouble shooting as well as cartridge defect repetitions will be covered at the end of this article.

12) Install the drum large gear side first. See Figure 14

13) Install the drum axle pin and screw. See Figure 15

25) Check to see that the mixing blade is in its proper slot. See Figures’ 26 & 27.

Try not to move the cartridge too much so that the mixing blade stays in place.
