Question about HP DeskJet 3940 InkJet Photo Printer
My printer is hp deskjet 3940.
When the ink that came with the printer ran out, I injected a generic into the cartridge. It printed well on its early printing but later the quality of print deteriorated until such time that it stopped printing. The printer's power indicator just kept on blinking.
I tried to clean it by wiping the cartridge's printing head and the roller.
After that the cartridge carrier never stop in the middle when the printer cover is lifted when it is supposed to stop.
The power indicator just kept on flashing.
It appears that the injection may have been lethal, it was still using the ink that it carries in its tubes then it mixed with the injection and is now blocked \ faulty. To repair it you could try getting a new set of HP inks.
