Cartridge leak in HP OfficeJet Pro 8720

[FLawg]

The magenta cartridge leaked into the cartridge bay on HP OfficeJet Pro 8720. This was a genuine HP cartridge and I have only ever used HP cartridges. I cleanup up the bay as best I could and installed a new magenta cartridge. Printer then indicated that yellow cartridge was empty, but I know it was a fairly new cartridge,. I replaced the yellow cartridge anyway. Then printer indicated the cyan cartridge was empty - again a fairly new cartridge. I cleaned up the bay again and made sure that the electrical contacts were clean. But it seems no matter what cartridge I put in, it says the cartridge is empty - so I can't print.  I tried turning the printer off and on again. Same result, Time for a new (non-HP) printer?

Please perform the below steps and let me know

1) Turn off the Router, Printer, and the computer/ mobile devices.

3) Turn on the Router first and wait for all the lights to stabilize. 

4) Take out the cartridges. 

5) Unplug the power cord from the printer & wall. 

6) Wait for 30 seconds. 

7) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector.
