MX922 Suddenly stopped printing magenta

[elise]

I was printing out flyers when printer ran out of magenta. As I was replacing it I noticed that the last several flyers that had printed before running out of magenta had a strong turquoise hue. Once the new cartridge was installed, the flyers were still coming out turquoise hued.

I printed an alignment print and nozzle check. Neither had any hint of magenta in appropriate spots. 

I purchased this printer on 5/19/2013 from Best Buy

My computer is the first Surface Pro running Windows 8.1.

 Please advise.

OK. For others searching this issue, I'd become convinced it was the printhead after googling around. I called tech support, secretly,praying for a discount of some sort.,,He led me through the deep cleaning proceedure and it worked!  Once again confirming that old adage about assuming.
