I used to be able to use non HP ink cartridges in my photosmart 5520 printer but now they get rejected with a message saying that the cartridges are protected. How can i disable this so that i can use the compatible cartridges that i have always used?
HP Cartridge Protection is a feature which locks a cartridge to a specific printer when the printer owner has enabled this feature, once a cartridge is protected to a specific printer it cannot be unprotected and cannot be used with any other HP printer, this is not related to HP Genuine or Non-Genuine cartridges, but to the specific cartridge itself.
You must replace the print cartridge to another one that has not been protected by an HP printer.
