HP 2600 is not distributing magenta evenly leaving red to orange

Just had almost exactly the same issue - except the Magenta was printing 2mm below where it should have been.

Went through all the recalibration menus multiple times and the factory restore etc. Then wondered about the toner cartridge. If the problem is just with the Magenta, maybe this is where the issue lies. The printer had remanufactured toners in it - all the others were fine. Went and found a new HP original magenta toner - printer did its default recalibration on startup and the config test page came out like new. Put the old one back in and problem reappeared.

Strongly suggest you try another toner cartridge - as I suspect the chip is to blame in some way.

HTH.

Crazy Coconut.

that is something called laser scanner contamination, behind the magenta catridge there is a little piece of glass wich is the laser scanner. clean the glass run at least 3 cleaning modes and then sent a test page and see if it gets fixed.
if not take the printer to a service center to make a deeper cleaning or in the worst case scenario to replace the lase scanner
