Risograph gr1700/gr1750 with film coming off

[Guest]

We have a Risograph gr1700/gr1750 and it appears that something is wrong with the drum. Please excuse my lack of vocabulary explaining our issue. I have attached a picture of the damage in hopes of getting help fixing it. I can't find a vendor to service it in my area.

We have plenty of ink and 3 master rolls so I hate to write it off if it is an easy fix.

Please look at the attached photo and let me know what we need to do. Thank you in advance for your help!

If you go to make a master is it just unrolling out of the machine?

When you placed the master roll into the Riso did you feed the lead edge into the master making unit?

Have you used it before? It seems the roll is backward but then it shouldn't unroll to the outside area?? Anyway, when installing a new master roll. Open the scanner then release the master making unit by the two green hooks one on each side. Then install the master with the existing end caps properly and lead the master under the green guides by the long black roller. Close the master making unit and the Riso should feed it to position automatically. And remember the shining part of the roll should be facing upward or your get blank copies....

The manual is in the picture. Might want to read it. Shiney side up on the master roll or look at the end of the roll and it will read colored flange.

Thank you again for your response: I reloaded the new master roll and now when I press start it stays master error and the numbers 7 & 9 light up. I tried taking the roll out and reloading it 3 times, but every time it misfeeds and gives the same error numbers.

Thank you again for your help!

With the 7 and 9 lit up, press the * key. It should display a code (I think these will do that, been a while).

If your machine has a problem opening the clamp to dispose of and load the new master, it could be attempting to feed the master to the drum, the drum doesn't dispose of the previous master and also doesn't accept the new master. Since there is a master currently on the drum, it will just feed the new master out if there's not enough ink on the current master to attach to. Do you have another drum to test?

I haven't worked on the GR line but have seen this on the newer lines a couples times. Maybe someone else who has more experience can let you know if this seems like a feasible scenario and maybe there's an easy fix.

Sorry, I haven't seen this yet so I have to ask -
Have you tried resetting your machine?

C21, load master error.
To reset machine: turn off, hold reset button down, turn on while still holding reset for 3-5 seconds.
Good luck.

Good morning,

I did a full reset and then tried to make a copy & it still misfed.


Thanks again for your input - gdh

Probably the allen screw for the gear that drives the write roller has backed out. Or possibly the load roller, might as well check both while in there. They are the two rubberish black rollers located in the master making area.

Like 20gaugeo/u said.
The hex screw on the write roller drive gear has come loose. It was a common problem on this series check the gear and the belt has to have the proper tension if not the master will fail to load proprely it is the pulley G in the picture attached. Hope it helps.
