Question about Canon PIXMA MP530 All-In-One InkJet Printer
I've only had this printer for maybe 2 months, used it 3 times, and now everytime I try to use it I get this error message..."More than one ink tank of the following color is installed. Black 
Use only one ink tank per color at a time."
So I open it up to find that ink tank full and the red light on and its flashing, I take it out and put it back in -stops flashing, and still get the same error message.
Its the correct ink, it has two black tanks, how can I fix this, I cant print anything!
I scraped the terminals in the printer gently with a screwdriver cleaned them nicely problem seems to be fixed

I have a Canon Pixima MP530 printer. I had the same problem with the  black ink. I tried cleaning all of the contacts with no success. I put another new  cartridge in and the problem was solved.

This was solved for me, it was the contacts, they sent me a new cartridge and I havent had a problem since, its been months.
I hope for all these ink cartridges getting tossed and replaced -they are getting recycled, suppose it's better than tossing out the whole printer.
Anyhow - solution is, get a new cartridge.
