Question about HP DeskJet F4280 All In One Printer InkJet
Replacing ink cartridges changes nothing; nor does aligning cartridges.
Ink lines are clogged, sometimes unfixable, Try deep cleaning cycle.

My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected

I had the same problem, all cartridges lights came on.
I did two things:
1st: I clean the print cartridges plugs with Q-tips, just to insure there wasn't any ink build on the plugs. If you look were the cartridges are, you will see four plugs one for each of the cartridges. Each plug has four contacts. They should be a bright metal color. If they dull in color, they have ink on them. Unplug the printer and pull all the cartridges out and gentlely wipe the the contacts with Q-tips. Re-stall all the cartridges.
Note: The cleaning did not solve my problem but its good maintenance since in was looking for a solution.
2nd: What work for me was I un-stall my printer totally. Turn off the printer then turn off the computer, had a cup of tea, rebooted the computer and re-install the HP cd disk and drivers, turn the printer back on. After I reinstall the software and put the printer back on my network, everything is working fine for the last two days. The lites are off and the HP toolbox is reading the ink cartridges status correctly. I believe that a virus change the printer drives.

has this printer been sitting around and not been used? possible problem is that the cartridges or the jets are plugged with dried ink. use a damp paper towel and carefully wipe the bottom of the cartridges to remove any dried ink.

You can bypass the alignment on 5610 by pressing ok to start alignment
and then cancel
after that check by printing a document if your cartridges work fine if not
you can refill them with this easy and cheaper method
