My risograph has broken and I need help to fix it. Until yesterday, my model GR 1700 machine was working well. Within the space of about 2 to 300 copies, it developed a problem. Here is my description of what is wrong: On copy 1, the registration of the print is fine (or not, sometimes copy one is bad). On copy two, the image is 3 mm further down the page than it should be. Copy 3 fine, 4 bad, etc. This is not always the case tho, the registration, when out is out 3 mm. But the order of when it is out changes. At times, it will do several good or bad in a row. Sometimes the pattern presents as good bad bad, or good good good bad. I have so far readjusted most settings on the machine, including the first phase paper pickup as well as the timing of the second phase. I didn't find any problems with them, and playing with them did not correct the problem. I have tried different paper and drums, as well as all the different speeds on the machine and the problem does not change. The only thing I have noticed, is after a period of inactivity or several hours, usually the first 100 copies or so don't have the problem. I require someone that can help me fix this over the phone. I am located in the middle of no where, so I can't take the machine in, and I need it working fast. Preferably yet this weekend. I will take your answer if you are person that can fix it, or you can arrange for me to talk to a person who can fix it. I don't think this is a simple problem, but I base that only on not being able to find it described in the service manuals. My guy feeling is that there must be something very very simple to fixing this. If you need clarification on the problem before you can answer, let me know. I know $25 isn't much for the actual solution, I'm setting the price there thinking I will end up paying whoever you find me to fix it more money. If you can fix it yourself, I will gladly pay more for the actual working solution.

Hi Bill, First of all I'd like to thank you for allowing me to post an answer. I consulted your question to a friend of mine who is in the copy business for many years. He said that the solution he suggested can't be found in the machine's manual because it is a type of problem that needs technical support from the manufacturer or someone who is knowledgeable in this type of machine. His suggestion came from your description "...the first 100 copies or so don't have the problem". This gave him the clue that the problem is caused by the feeder. Actually he also mentioned oiling the rollers because your machine is an old model and these may need oiling. I did not mention it anymore because he emphasized that the problem is in the feeding mechanism. I then relayed his suggestion to you and I'm glad it worked. Again, thank you very much for informing me and for visiting us and I hope you become a frequent and happy user of Google Answers. Best regards, Feilong

Under your feed roller is piece of plastic film. It separates the paper. Remove your paper feed and under the feed you will see a small square type box. On this is the plastic film. It is self sticking. This may be your problem. Danbob
