HP 3550 manual Print cartridge authentication, HP fraud hotline

Print cartridge authentication

The printer automatically authenticates the print cartridges when the cartridges are inserted into the printer. During authentication, the printer will let you know whether a cartridge is a genuine HP print cartridge.

If the printer control panel message states that this is not a genuine HP print cartridge and you believe you purchased an HP print cartridge, see HP fraud hotline.

HP fraud hotline

Call the HP fraud hotline (1-877-219-3183, toll-free in North America) when you install an HP print cartridge and the printer message says the cartridge is non-HP. HP will help determine if the product is genuine and take steps to resolve the problem.

Your print cartridge might not be a genuine HP print cartridge if you notice the following:

●You are experiencing a high number of problems with the print cartridge.
