Image on master (Risograph GR3770) is not centered when burned.

On our Risograph gr3770 when we burn a master from the computer thru a rip the imprint on the master is not centered when burned. The image is shifted so when it is printed on the letter size paper it is so far down that even adjusting the print position all the way to the right, the image is still not centered. What could be causing this and how do I correct the situation?

SOURCE: Paper tray will not lift on a GR3770

either the motor is not turning to lift it up or the gear is broken, do you hear the motor turning when the tray is pushed in? take the tray out and look in the back to see if there is anything blocking it also.

SOURCE: Risograph GR3770 - cannot pul out the drum, Error

This solution is ONLY for pulling out the drum.
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.

How do remove jammed master from the disposal unit on a risograph GR3770?


This model is pretty obsolete, finding someone to service it will be difficult, and most will only promise to attempt it and not warranty the work, never the less, its what I recommend. If you must attempt it yourself, I recommend a set of picks from Menard's (around $5 for a set, they look like dental picks) and an exacto knife and then cut the master free in small pieces.

most riso techs who are trained on these will do a partial disassemble. If this were an RZ or an EZ I'd be willing to try talking you through that. I don't recommend it if you're a novice on these though. They're much crankier.

How do i remove jammed master in disposal unit in a riso gr3770?


On the back there is a box where the masters are used, remove and check for any play between the master and the shipping box. Open trough the green lever the lid covering the box used masters and check the part that carries the master used for the box, if there pieces or entire master mired in this piece. Let her go trough the alavacas extremities. Make sure the drum is with the clamp without damage, because it holds and releases the master of the carregamanto and unloading of master. Remember these tips without seeing the machine and if you have knowledge of the equipment inside are a little difficult, but be able to get there. I hope I helped you.
