Accidentally pushed the drum-tray back in without the drum? The green light won't show, and the tray won't budge - all you need to do is to carefully push a tiny lever below the tray, as pictured.
good luck

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
