Got a couple without fail every couple months, developer transfering to drums and ending up in the waste box.
Works perfectly when replaced.
Have replaced all other consumables, and on last call also HV board. Time will tell if made a difference.
Machines are far apart and not the same customers.
Hv contact assembly looks fine. NFI what to do next. Near new machines too.
Total colour count on this one 10k and 5 yellow ius in this time.
