[Misc] HP Color LaserJet 8550 drum discontinued C4153A

[Robinh]

I have one of these on maintenance and all of my suppliers say that the C4153A drum unit is discontinued. Someone suggested I use a Canon EP82 drum, but they are discontinued also.

Does anyone know if I can still get one of these, or has anyone had success using a compatible drum unit?

Is there a way to reset the drum count? I read in another thread where someone suggested opening the door then pressing "yes" when it asks if this is a new drum. I don't think that works.

Thanks!
