Multiple error lights.  Re-seated new Canon ink cartridges.  Error message keeps changing.  Two of same color. Or Cyan error, or Magenta Error

Replaced all ink cartridges with CANON cartridges.  Last error code 1681, but many different ones as lights keep blinking.

Error 1681 indicates two inks of the same color was installed in the printer.

Error code says 2 cartridges of same color ink, but this is incorrect.  Each cartridge is a different color ink, matching the color code where inserted in the printer.
