Riso GR3750 T6 Error Message

[Guest]

Dear All, I have a problem with my Riso GR3750. Error message T6 appeared on the display. I tried to reset the machine and reload the master roll again but nothing happened. Also the color drum seems to be blocked. Do you have any experience with this kind of issue or some solution? Thank you in advance for your help! Josef

Error code is pressure assembly, for the impression roller. Motor, sensor or screw drive broken? Got a service manual and parts book? Good luck.
