Question about Riso RZ220 Duplicator
I changed the master drum to another color that has not been used in some time. The RISO made this horrible noise and threw an system error T01-521. I reset and turned off and back on several times. I have attempted to change the master drum but it will not reslease from chamber. Any way to release it?
assuming you have a RN machine
you should of removed the master on the drum by hand if it was not used for more than a couple of weeks, and wipe dry under the clamp.
To get the drum out, hinge up the top of the machine over the top of the drum there is another small door, it hinges up like the top of the machine.
At this point ensure that the drum is in the home position i.e the clamp of the drum is at 12:00 (on top). if not turn drum to that point by hand.
Then try the button again to release the drum. If that fails there is a small **** under the drum at the front door area. there is a catch there that holds in the drum which you can move to the side with a flat screw driver.

The drum is not on its normal position when you insert the drum unit, try to insert a flat screw driver under the drum unit. There is a rectangular slot under the drum unit on the front of the machine, gently insert the screw to unlock the drum manually. Refer to the manual for gear alignment if ever there is a misalignment of gears.
