Error message for colour ink cartridge in HP ENVY 4520 All‑in‑One Printer series
You might get this error if the cartridge is not compatible with the printer. It is also possible that the cartridges are dirty or misaligned. In some cases, it can occur if the printer firmware is not updated. You can try updating the firmware as the first step. If your printer is connected wirelessly, then connect the device with USB for some time and follow the link available on the manufacturer’s website to install the recent firmware update on your printer.
In case it doesn’t work, perform a hard reset on the printer. Make sure to connect your printer directly to a wall socket and not to any spike busters or surge protectors. With your printer powered on, unplug the power wire from the back of the printer and the wall socket. Unplug the USB cable if inserted. Wait for close to 3 minutes and then press and hold the Power button on your printer for close to 30 seconds to remove the remaining charge.
Plug back the power cord directly to a wall socket and not to an extension cable or multi-plug socket. Now, plug back the power wire to the printer. Power on your printer. Wait till the warm-up session concludes and the printer is idle. If this didn’t help, inspect the cartridges. Check if they have complete electrical contact with the printer. Take out the cartridges carefully from their ink slots, remove the protective labels from the contacts if necessary, and reinsert the cartridges. The left slot holds the tricolor cartridge, and the right slot holds the black cartridge.
