Officejet 5740 is Not Recognizing the Correct Cartridges

[Rmdst3000]

The printer, Officejet 5740, is not recognizing the black or the color cartridges which came with the printer. The printer gives the error “Incompatable Cartridges.” The cartridges are #62.

Yes, the protective tape was carefully removed. None of it is left. Yes, the copper connectors are clean. Yes, I tried reinstalling the cartridges several times. And yes, I restarted the printer servers times.

Please advise. Thank you.
