[CQ] Pink Hue on prints/copies MX2640

[BryanW]

All printed or copied pages have a pink hue on front frame third of page. Pink Hue is on the image area only and not the whole page. Have replaced magenta drum, magenta developer unit, primary transfer and laser unit with no affect. All other colors are fine front to back. Any ideas?

Have you done a complete calibration? I've seen something in simulations regarding front to rear on individual colors but I can't remember the number. Only thing I can say is look through the color setting sims

Rum SIM 64-1 pattern #9. This will produce full density from all 4 drums.
Your post stated you replaced magenta drum; did you do the blade and charge also...?
A flipped cleaner blade in the magenta drum unit will cause this exact symptom.
Also inspect the jam log as most flipped blades on this model are accompanied by a PPD2_PRI jam code.

Try 61-13 laser power correction mode to reset f/r density, then try auto adjustment 61-11.
