Crop codes for an AR 207

[Ricoh Dicoh]

I'm trained on ricohs and know very little about working on sharps. First off i was wondering if there's a general crop code to get into service mode like on the ricohs?
Next I need to know if I need to enter a re-initialization code for changing out a drum and developer section on a AR 207

To get into the service mode on a Sharp AR207, hit Clear -> Interrupt -> 0 -> Interrupt.

Developer initialization code is 42-1
Drum initialization is 24-7
