T-4 is an ink overflow condition. You may need to check and clean out ink section of drum. Remove the ink then press reset button. Then turn off and on and re-insert ink.

Hello we have a RISO GR 3770 - and the cloro drum is stuck in the machine. the green light is not on. how can we get the drum out?


Open front door. If you look at the metal housing below the drum you will see a plate mounteg with two screws. Get it off and you will see a small lever. Turn it right to loosen the drum. Be extremely careful when pulling out the drum. If the drum is not in zero-position it might be a bit difficult (e.g. have a look at the master clamp). Please note that it may be difficult to insert the drum again.

Riso 3770 error code T3


A T3 error code is indication of some kind of problem associated with the clamping mechanism. Most of the time, what happens is that there is a magnet attached to a flag on the rear side of the drum and it has fallen out of place. If you can find the magnet, reattach it with a strong adhesive.
Check for smooth operation of the clamp by hand as well and lubricate if necessary.
