This exact thing just happened to me. I tried EVERYTHING in the way of troubleshooting - turned printer off/on, plugged/unplugged, opened/closed top, pressed all the buttons on the front right - FINALLY, I took out and put back in both ink cartridges and the light finally went to just green, as it should be AND it printed! Hope this helps!

An interesting aside is that if one or the other cart is removed, the appropriate LED goes out and the other blinks. At least some of the sensing circuitry sees the cart.
Anyone have a schematic of the cart/printer electronics?
SOURCE: lower light blinks on everytime I try to print anything and nothing prints
tried new artridge and no paper blocked yet still flashing
SOURCE: orange light blinking on check your cartridge keeps coming on
Please go to this link at HP online support and follow the instructions to reseat, and possibly clean your cartridge contacts. Try reseating again if it doesn't work the first time. If you're not successful, you can try to reset the printer by turning it off, uplugging the power cable from the back of the printer, wait a few moments, then reconnect and turn on. Sometimes this will clear the error light.
Don't use the cleaning and alignment tools unnecessarily, as this can compound the buildup of ink around the print head.
If all this fails, you may need to replace the cartridge to get the printer to work...the fault is not always a lack of ink.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
