I have had problem with missalignment of the colors on my CM1312.
At first it looked like I had problem with the black and mangenta.
So I tried to do multiple calibrations of the printer. (And it calibrates it self every second day.) But the problem remained.
The black cartage was almost emty, so I replaced it with a new one. Then I only had problem with the mangenta.
(How can this be physicaly possible? Isn't the color cartages just dumb color containsers with a selen drum?)
So now I have replaced the mangenta cartage even if it had 9% left. But it did not solve the problem.
The mangenta printing is 1mm off to the right and also 1mm down compared the the black.
And it is not even over the whole page. See some corner parts from the diagnose page below.

When I struggled with the problem the yellow cartage was at 3% and cyan at 12%. (Black 99% and magenta 9%)
So then I replaced also the yellow cartage. And now the printout looks perfect!!!
How can a almost empty cartage damage the alignment for another cartage?
Can someone from HP explain that too me?
The corner part from the diagnose page now looks as follows. Not 100% perfect. But almost.

The toner level is now: Black:90%, cyan:8%, magenta:96% and yellow:100%
I wonder if the colors will be more and more misaligned when the cyan level drops closer to 0%?
