Have you installed the print head? It's a separate item in a foil colored sealed package. It must be installed and locked in before inserting the ink tanks. If you have done this and still get no lights on the ink tanks, there is something wrong with the unit itself.

plz check you have placed the ink tank in the appropriate slot otherwise you have to try with new one

If the error code is actually 5100, this is how you fix it:

Open the paper output tray.
Lift the scanning unit (printer cover) completely. (The print head will move to the replacement position.)
Open the inner cover.
