My 6830 printer stopped printing red and yellow

[ChristopherB]

My 6830 all-in-one stopped printing yellow and megenta, only black and blue. The cartridges are HP cartridges and are full. I've run test pages from two separate Mac computers and cleaned the heads at levels one and two.

The printer's out of warranty.

Ideas for me?

Are you able to make photocopies?

Thank you, Krazy Toad. You were absolutely correct. The printing problem was due to the print heads. When I wrote my post, I didn't wait long enough for the second level printhead cleaning to work. Lo and behold, a few minutes later the test page printed correctly as did several of my own tests printing existing pages. Thanks for paying attention to my question.

I wanted to acknowledge my own impatience and that you were indeed part of the solution.

Many thanks,

Christopher B
