I get the error code 1401 on boot up of the machine?
A, The chips on the cartridge have become too low and need to be reset using the below sequence. Turn off the printer and reboot, when the non-genuine message appears you need to click Proceed, then yes then no. the printer will boot up to the ready state which will allow you to reset the cartridges. Press the Shift key followed by the eject key (Cartridge reset key on echo 2) it should display ink level reset and the machine can be booted up correctly.
