Hi Lynn. Welcome to justanswer.
C000 is a diffuse error in the Canon printers and can occur for several different reasons. This can be due to problems in the purge unit, or mis-seating of the ink cartridges . I recommend that we proceed with checking the ink cartridges, as issues in the purge unit require Canon repair or replacement of the printer.
If you turn the computer on and set it up for replacing the ink cartridges, does it move the print-head carriage to the replacement position?
Reply so that we can proceed further
