* For a compatible, remanufactured or re-branded ink cartridge which has been purchased on-line or at select retailers (i.e  sold under a different label than a trademarked HP, Canon, Epson or Brother cartridge) we would need to know this as well to properly assist you. For ease in identification, remanufactured (original cartridges which have been refilled but exhibit a different brand name) and clone/compatible cartridges (some of which are illegally imported into the US/Canada) will NOT have the HP, Canon, Epson or Brother trademark logo engraved or affixed to the cartridge’s top or side label.
