Canon laser fax machines take all-in-one cartridges named with a short code printed on the cartridge itself, typically S35 or an FX number such as FX8. Both black toner and remanufactured versions appear in this section, with the description stating which is which. The cartridge combines toner and drum, so replacing it restores print quality as well as darkness.

Canon also assigns a long order code in the form 8955A001AA or 7621A001AA, and catalogues sometimes list only that version. The two refer to the same item, so if a search on S35 or FX8 does not find what you need, try the ten character code from your paperwork instead.
