Hello!!!  My HP OfficeJet 6962 is blocking my cartridges.  My printer is no longer covered under warranty and I would like to use whatever cartridges I want.  I have tried all of the online hacks to fix it and nothing is working.  Unfortunately, all of the hacks are for other models.  I am unable to install the updated firmware because my printer is greyed out on the install prompt, and it will not allow me to select it in order to install the update. Is there any way to fix any of this?
