I have the HP OfficeJet Pro 7740. I replaced all of the ink cartridges at once with recycled HP original ink cartridges. The yellow is the only one without a problem. The other 3 are highlighted in its message to "Remove and reinsert....". Is there a software or firmware upgrade needed to get my printer back to normal? I have tried the partial, semi full and hard resets ...all of which did nothing to help. I also removed the print head from the machine entirely and examined every contact point within the head and where it lands back in the printer at...everything is clean and clear.
Please met me know what I am supposed to do now. With all of the distant learning and remote work we are doing from home - this printer is an absolute necessity. I have hundreds of dollars in it and I can't afford to start over right now.
Please provide me with some solid answers as soon as possible.
