After replacing ink cartridges, printer prints colors differently. Help?

[jrmgriffith]

I have a Canon Pixma mg6320.  I replaced the yellow cartridge to no problem.  However, after I replaced the magenta cartridge, all of my reds look terrible.  I am printing something with some deep red-oranges, but all of them come out pure magenta.  The magenta color even shows up in the print preview!  What is happening??  This has cost me a daw of work.

I am going to ask the very obvious question:

You did get each cartridge in the correct place?

You are using genuine Canon cartridges and not off brand or refills? <-----this is very important

You have the correct paper settings?
