HP Officejet 5740 e-All-in-One Printer
TH51L331HB

I have had this printer for several years, and print wise work quite
well. However lately, it will not recognize the color print cartridge.

This is he second cartridge with which this problem occurs. It is a
genuine HP cartridge so that should not be a problem.

I have cleaned the contacts on the printer and on the cartridge with
alcohol on the assumption that that was the problem but it still there.

Can someone offer some suggestions on a course of action to fix the problem.
