I have a C252 in the field that gives a blank magenta copy. We replace the magenta drum unit and still same issue.

Check to see if laser from write unit is blocked.

Or the primary transfer roller may be out of place on the transfer belt.

if none of the above first, it will be the HV board, then failing that the PWB-M

(assuming some d/h hasn't damaged the flat ribbon cable to the laser relay board when changing a main motor in the past)

I would print some magenta rich pages and stop the machine half way to see if the image is on the drum or not. That could eliminate the drum and write unit.
