Cartridge install error message.
Canon TR4520 PIXMA 1682 COL Install ink cartridges correctly
I have taken the cartridges out several times, replaced with new cartridges, cleaned the contacts on both the cartridges and the printer and turned off the printer even unplugged it and continue to get the same message. Don't understand why I'm just now getting this. Have printed with these for over 2 years now.
The 1682 COL error is an indication that your PIXMA TR4520 does not detect that the color ink cartridge is installed in your PIXMA TR4520.
Please remove the color ink cartridge from your printer and verify that all of the cellophane / orange tape has been removed.
Also, please make sure that you are using genuine Canon ink and that you are using CL-244, CL-246 or CL-246XL.
