    Re: Riso RZ 200EP Paper feed issues.

    If it's a J08 it could be nothing but a dirty paper IN sensor. If the copy count is low it may have the original FT and sep pad in it and maybe they just need replacing. Then feed clutch may be...

    [Jamming] Re: 3051ci Jam 4019

    This sounds familiar but would have happened years ago on a 3050ci flavor... Firmware fixed I believe

    [Error Code] Re: RISO GR3770 Clamp Error

    Yes it's normal to hit the plastic when opening and closing, but if it's binding on it that's not good. If you haven't done it already you can open the scanner clam shell top and rig the 2 safety...

    [Error Code] Re: RISO GR3770 Clamp Error

    Some light machine oil or WD-40 like stuff would be fine.

    [Error Code] Re: RISO GR3770 Clamp Error

    I don't remember ever running into that plate being bent but from the looks of it it may be nothing more than a grounding contact plate, looks like 1 screw so take it off and see. Doubt it was ever...
  8. Re: Riso 2-color print getting pdf artwork onto both drums

    Might as well go back to the beginning and ask what model Riso you are using and if you are using the right driver for it and hopefully it's not a Mac you are using. Riso and Mac don't get along all...
  9. Re: Riso RZ390 Making Blank prints no image on master

    Never had an entire TPH go out, let alone twice. Segments go out and fail yes but not the entire thing. Bad board or wall outlet power problem frying it. Is it on a surge???

    Re: Riso drum wide vs non

    Well, if you set both drums on the table they should be the same length. It should pop a code if the drum is the wrong type installed. I believe all RP's are wide, shorter drums were the smaller RN...

    Re: GR3770 Feed tray stuck at the top
