First released in June 2008 the Okidata B2500 machine is based on a 17ppm, 600 dpi MFP engine that has a first page out in
less than 13 seconds. These machines can print, copy, fax and scan. The printers come with a starter cartridge rated for 2,000
pages and the standard cartridge (56120401) is rated for 4,000 pages at 5% coverage. These machines use a somewhat unique
method of telling the printer a new cartridge has been installed. Instead of a chip on the cartridge they use a key card that is
inserted...

1. Remove the two silver pins, one from each side of the
cartridge. Pry them out with a small jeweler’s screwdriver and
then grab them with wire cutters to remove them.
2. Remove the Torx screws and plate from both sides of the cartridge.
The Torx screws used in these cartridges are size T-7.

11.Install the drum axle from the hub side. Make sure the keyed end of the axle is installed first. It is easier if you mark the keyed
end with a marker so you know how to orientate it when installing it. The side marks in the left photo show the orientation of the
flat or keyed edge. The top mark in the right photo shows the keyed edge location.
