Riso FR2950 Feed Problem HELP!

[BluePlanet]

I have a strange problem with my FR2950ui. I can print the first side of a sheet with only rare misfeeds of paper, usually a max of 3 sheets once in a while.

But then when I print the second side I get constant misfeeds. Sometimes only a few sheets, other times 6-7 sheets go through and worse, all too often 10-20 sheets go through at the same time jamming the system. Maybe a third of the sheets get printed, a third I can reuse and the other third are trashed. This is a disaster, especially as I have 2000 menus to get printed asap.

This has happened on several jobs, 8.5 x 11 and 14 inch paper.
The paper feed wheel seems okay. This machine only has done 3800 masters and printed 126,000 sheets.

I noticed a thread on a GR. Does the FR have similar adjustments, and where are they?

Increase the angle of the sep pad when running the second side. (it's that green dial thing right were you put the paper)

Just to be sure are you positive the sep is good? If so the adjustments mentioned are correct.

Sorry sep = separation pad that is under feed tires.

Confused

The green dial thing, which I had not noticed before as half is broken off, simply seems to move the paper platform guides one way or the other, in order to center the image on the paper.

Above the feed wheel there is an up/down green switch for "Normal" and "Card." There is the green buttom to move the paper platform down.

The sep pad is just a slightly raised rubber pad that looks glued down and no apparent way to adjust it.

Nothing else is apparent.

Could I thicken the sep pad with something? Might that help?

Any other ideas?

Get a new pad and with your mention "green dial thing, which I had not noticed before as half is broken off" get a new of them also.

[BluePlanet]

As I said

It is broken, but I can turn it fine. It moves the platform paper guides side to side.

You didn't answer the question or provide anything that explains the angle adjustment. So you don't really know?

[Joe Foe from Buffalo]

The knob below the feed rollers and separation pad doesn't move the paper guides....so you must be referring to some thing else like the paper side guides. A picture will tell us what your referring to. As for the angle adjustment via the knob below the separation pad, it's trial and error adjustment for different types of paper or needs and so easy Riso put it in that location so even a customer with no service no how can figure it out.

The directions could have been better...

Well, I didn't see them as the paper tray was up and it was blocking the view of them. I looked under the tray and found them. Now that I have turned the machine back on and the tray went all the way down, there they are. Never noticed them before.

As I have knee problems never got down that low to look straight at it before.

So can you tell me the meaning of the knob with the small to increasingly larger circles? And what about the one with an arrow of descreasing size?

None of the messages on this have been very specific. Reading minds across the internet is a skill I have not mastered as of yet.

The green dials are to adjust the the flat pad that the paper goes onto under the roller that has the ribs on it. You can adjust the height and the angle it sits at. Both of these are critical. I also find that if I don't let the print dry off properly it will give multipule feeds on the second side. For this reason I always leave a day between printing double sided. GR & FR are similar in respect of paper feeding.

LOL Ya I could never do support via the web or phone with limited comunications. Hmmmmm, With your reported/posted location I would be happy to come service your mach's while on vacation if you can work out a deal I can't refuse on places to stay and see and eat form 2/13-2/21/10 which I could be on call if what I do dosn't fix it the first day. Plus I can fix just about any thing that handels paper too if you have more to get fixed. My GF and I allways have wanted to go see the Fort Jefferson that we all most did go see last time we visited.

Crisis Averted...

I figured out the use of the two dials and solved my problem. Thank goodness.

You wouldn't want to come to Key West now, we are having the lowest temperatures we've had in 130 years. Of course, everyone north of us is having lower temperatures.

I will probably have to learn how to service these machines myself, but if something critical happens I can't solve I will keep you in mind.

Before there were laser printers and ink jet printers, I owned and operated a typesetting business using 4 Compugraphic typesetting machines for about 12 years. I learned to fix those so good that Compugraphic offered me a job, but I didn't want to move and give up my business. The Risographs are a bit more complicated than those.

LOL I live south of Buffalo NY on Lake Erie (Lake View NY) last night the temp got down to -10. High today 18. To me I think your temps would be nice no matter how low at this point. Ya let me know if we can work out a deal...but sooner the better so I can try to get a good deal on getting possibly flying and convince my GF to go also.
