I have a HP deskjet 840C printer. This is not so much a problem, as it is something I am curious about.
The color cartridge is probably getting out of ink. The blue is printing out green, the red is coming out light yellow and what should be yellow/green is coming out a dark pinkish.
I printed a test page and blue and yellow were absent. Question: Blue & yellow make green, so how can it be printing green and not be printing the two colors that make up green? Anybody?
