HP 64 was the wrong cartridge for my copier. I returned it for an HP62.

Hello John I am sorry the cartridge you purchased was not correct for your printer. I am glad you could exchange the cartridge for a more suitable one. It appears your cartridge was fully functional and just mismatched for your printer. Please let us know if there is anything more we can do for you!
