There are several Risograph Z-type drums, most of which are not universally compatible.
Use the following charts to determine compatibility with your machine:
North American Models
RZ 590 & 390 Compatible
MZ 790 & RZ/MZ 990 Compatible but Drum Code Entry may differ
MZ 790 Drum Code Entry (Test mode #1210): 69
MZ 790 can be converted to MZ 1090 with special kit
