May the 7th I begin my residency at Frontyard. My main quest is to do a cross stencil project between my Gestetner 120 a manual duplcator from the 1950's and the 1980's Risograph which lives next to the library at Frontyard. Today I start as a first time Riso user and already had several moments when the Riso said 'no'. So let this page be a log of tips and tricks with keeping the Riso printing for future Riso users.

Riso Terminology list:

- Master ----> this is the stencil that is created when you scan an image on the Stage Glass. The master wraps around the drum and because of this becomes a one colour master. When you want to use the colour drum of another master your master is wasted in the machine.

- Stage Glass ----> I put this here because I think it is a cool name but I think you know what it is.

Problem log;

- "T3 error call service" my suspicion is that this is a clamp error during master making (googled the error) which means the trouble is because either the master won't come off the drum or won't go onto the drum. The solution is to remove the drum press reset and re-try. This worked sometimes. Other times I opened the latch of the master roll and had a look in there. Sometimes the master was not flat having folded into one of the rollers I straighten it up. I am not sure which of these methods truly solved the problem because sometimes it required a combo of these things. You can also manually pull the master off the drum and empty the drum of masters which also seemed to resolve problems as I went along.

- "Paper under drum error" The Riso seems to have very clever sensors that can tell you what the problem is. Sometimes you do them and the problem is fixed and it continues to print or make a master. Other times you can see for example there is not paper logged under the drum. To resolve this problem press the 'reset' but and the machine is able to print again.
