[Misc] Riso RZ390 impresssion roller out of position.

[Visirecord 101]

The impression roller of my Riso RZ390 is in the up or engaged position with the drum removed, so the drum cannot be reinserted. Malfunction occurred without any corresponding evidence of it jumping time like loud noises etc. Dont know how to determine home position of various gears or if the Riso has an electronic actuation of the roller in addition to the cam operation. I also have an old Ricoh machine so am familiar with some repairs overall. Any Help greatly appreciated.

greetings friend you should get you in the back of the machine remove the cover and check the spring pressure that is not broken and also check that the solenoid pressure is working correctly
