I've replaced the ink in this printer with legitimate Canon cartridges and it's still saying the black one is low.  I've done all the reset options people have recommended in other posts and it doesn't work.  I've run it through all the cleaning and maintenance options that it has.  And apparently I have to pay to talk to someone about it.  I might as well put that money towards a new printer.  When I print something it prints it in gray scale. Where there should be a bar code, there is just the outline.
