I JUST REPLACED THE BLACK PRINT CARTRIDGE ON MY CANON PIXMA MX310. NOW 90% OF THE LETTERS PRINT BLURRY. ITS AS IF THE PRINTER IS TRYING TO SUPERIMPOSE ONE LETTER ON THE TOP OF THE ORIGINAL BUT IS OFF-CENTER. I DON'T REMEMBER HAVING THIS PROBLEM BEFORE. IS THERE A WAY THAT I CAN CORRECT THIS?

THANK YOU.

The tech support number for Canon is 1-800-828-4040.
If your printer is under warranty (1 year after purchasing) their is no charge however, if it is out of warranty the service charge is; I believe; $9.99, that's if they can fix the problem, if not, no charge to you.
Good Luck :)
