Due to shiaty design, it is easy to accidentaly puncture the printed
circuit with the sharp end of the retention spring while inserting a
new cartridge. Use a flashlight too look at the white/copper
sheet the cartridge makes contact with and look for a puncture
(probably near the lower right side.)

Dear friend, your Black Ink Cartridge is Empty thats why your printer is using the Colour Cartridge to produce the Black Colour. This is the reason you are having Dark Reddish Brown colour instead of Black.
defective carriage. machine is brokeded (pronounced BROKE-DEAD). part unavailable, cannot be fixed, if machine is still under warranty then either take it back where you bought it or contact HP for replacement.
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
The Deskjet 6940 will only show ink level for original HP cartrdgies. Refilled or reman cartridges will show as empty or unknown in the toolbox. This is not an issue with the driver, the cartrdige itself has information that it has been previously used and this is not resettable. You can continue to print with a cartrdige that has unknown ink levels, you will just not get low ink warnings.
