Ink Alert light flashing with new ink cartridges, and won't print, why?

Welcome to HP Forums. This is a great place to get support, find answers and tips.

I understand that the printer lights keep blinking when you install new cartridges but it works fine with your old cartridges.

I'll try my best to help

I suggest you start with a Printer Reset and download the Firmware 

(1) Turn the printer on, if it is not already on.
(2) Wait until the printer is idle and silent before you continue.
(3) With the printer turned on, disconnect the power cord from the rear of the printer.
(4) Unplug the power cord from the wall outlet.
(5) Wait at least 60 seconds.
(6) Plug the power cord back into the wall outlet.
 NOTE: HP recommends connecting the printer power cord directly to the wall outlet.
(7) Reconnect the power cord to the rear of the printer.
(8) Turn on the printer, if it does not automatically turn on.

The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.
Wait until the warm-up period finishes and your printer is idle and silent before you proceed.
