How do you use a risograph?

A Riso is pretty easy to use if it's in good working order -- very much like a conventional copier. In operation it works more or less the same: put your original on the glass, close the lid and hit the green button to start. If your paper supply is loaded and consumables aren't empty you'll have a copy in about 20 seconds. Here's where it's different. You'll wait 20 seconds to get your first copy out because it's making a master (reverse stencil) to wrap around a drum and squeeze ink through to print on your paper. If you've ever seen an old mimeograph the process is the same, just automated. If you need a single copy a Riso is the wrong device to make it on because the stencil costs and wait time make that impractical. In my shop, if I need 200+ copies I will use a Riso, otherwise I use a conventional copier. Risos can be wonderful for what they're designed to do: make a single image many times, very quickly, very inexpensively. I have three Risos and when I need a whole pile of fliers I can crank them all up at once and be printing 380 pages per minute...when they're running right. None of mine have been anything to brag about for reliability. Here's what a Riso will not do for you. They won't give you a high-resolution image. (A couple of mine claim to be 600dpi, but print quality's just not that good.) They won't print collated material like any desktop printer will, since they can only do a single image repeatedly. They won't do impressive full-color work, since you have to put paper through multiple times using different ink colors like an old offset press. So to recap, if you're considering using a Riso you're looking at wonderfully low cost and efficiency for single images on almost any paper. (They will practically run cardboard.) If you can fix them yourself and you like repair challenges (as it seems a few people genuinely do) then they'd be a fine investment. Just know that parts and experienced advice are going to be extremely hard to find. I called a copier repair company and told him I had a problem with a Risograph and he said, "A problem with a what?"
