I have an MX2610 that has pulled color developer out of DV units 3 times in last year and a half. Twice it was yellow and once it was cyan. I have updated firmware, replaced all ATC sensors, yellow DV unit, MC/DV PWB, PCU PWB, LSU, and all MC units. I also installed an uninterrupted power supply. Don't see any nicks or wear marks on the drums. I have had this happen in a couple other machines in this same series, but not repeating like this. Just looking for some guidance as my head is spinning.
