Hey there!
I think we had a similar issue on our RN2150.

I seem to remember it having to do with the 12 or so small rubber belts that pull the used master off the drum.
Very often these wear...

;) GOOD NEWS! it was a stupid electrical problem.
The lesson is don't set up a Riso studio next to Tram lines and expect the electrical imbalance not to affect your equipment!

Hi All,
we've got an RN2150 risograph with an SC9750 RIP connected via an old modem's ethernet cable.
Its been working wonderfully for at least 3 years.
Now it it mysteriously not turning on...

Hello eveyone,
we're running an RN2150 in B4 format. Its now getting harder to source real OEM masters for our model and we have recently experimented with using master rolls from different models...

Hey there Huckleberry,
we have a 2150 so I would hope the problems would be similar.

We had this error when we mistakenly bought an A4 size drum and tried to put it in our B4 machine.
The only...

There are some legendary RISOGRAPHERS in the Netherlands that have allegedly managed to make and refill their own inks as you describe. Try checking out and writing to Extrapool

BIG NEWS: SOLUTION FOUND!

much stupider than I thought. I'm more familiar with mechanical problems as opposed to electrical ones so I had completely overlooked a BURNT FUSE in the right-side...

Thanks for the pointers Iowatech, although the drum lock is the least of my problems! Luckily the machine gave the error when the drum was already in the home position so removing it was not at all...

I've tried swapping out drums, but, if my reasoning is correct, the problem must be on the machine-side (not the drum itself) since I get the error even with no drum mounted.

Iowatech, thanks...

UPDATE #2
I have managed to open the front panel cover and access the two solenoid counters, nothing apparent is wrong with them.
I have also tried running 095 in Test Mode (Solenoid counter...

Hi Iowatech, thanks for the suggestion, alas it did not make the error go away!

Update on the situation: I have managed to manually release the drum lock so I removed the drum. Now I just need to...

Hello RISO users!
We just finished printing a huge job on our Risograph RN2150, many colors, many pages.
After we finished, the black drum was inserted for another print, when all of a sudden the...

Hi everyone,
I'm writing from Italy in Torino where I have a Risograph RN2150 in B4 format.

I currently have 5 drums (Black, Blue, Red, Grey, and Purple) and looking for more colors, especially...

Hey Alfasud, thanks for the suggestion.
I eventually had to have the only riso technician in Torino (where I live) come and fix my machine...
he had to disassemble the cutter unit, remove it and...

Hi there Riso-pros,
I have a problem with my risograph RN2150EP which I bought from a person who literally used it to make only 9 prints (!), so its pretty new considering the age of the model.
Up...
