Question

how to override low ink message on Cannon PIXMA MX452

Answer 1

Remove any cartridge(s) that the printer thinks are low. Look at the bottom for the rows of copper squares. Put a thin strip of tape on the top row and put it back in the printer. Close the lid, wait for the error message, and open it again. Remove the cartridge and add an additional piece of tape over the next row down. Then put it back in, close the lid, and wait for the error message. Remove the cartridge once more and take off the tape, then replace it. This essentially "tricks" the printer into thinking it's a new cartridge. Repeat with any other cartridges showing error messages.
