Hi! So I have just purchased a secondhand Risograph GR3770, and this forum seemed like something relevant for me to join.
My goal is to print comics and small art books for myself and others, and to learn how to service/fix the machine when I need to. I'm an illustrator/self employed artist and I'd like to think I am quite good at problem solving, but other than a childhood love of meccano and a few semesters of basic high school electronics more than ten years ago, I haven't got much experience in anything like this. I assume there will be a lot for me to learn.
At the moment my first issue is a T-11 error... I've researched (reading some manuals and forum posts) already and found this means a 'pressure control motor lock' and means that the pressure sensor is not functioning properly, taken the back of the machine and had a look around, but I'm a little scared to actually take anything apart because I'm not entirely sure what all the parts are. If you can help with this, maybe have photos of which parts I should be looking at and what I should be looking for, or just general advice for someone just starting out with a risograph, it would be greatly appreciated.
