    Re: EZ221 Replace ink bottle message

    There's a small screen filter inside the pump (have to pay attention to the curvature of the screen when reassembling). If it is colored ink it can get gummed up from sitting around and not being...

    Re: riso ez370 ink Overflow problem!

    Using generic ink? If it's runny and got into the one way gear of the squeegee gear can cause slippage. It was more of a problem on the RZ line. I think you can shine a light in the back opening...

    There should be a date stamped on the end. Anything older than 2 years toss and start fresh
  6. [Misc] Re: RISO RZ Drum whistle noise on black ink.

    Yep it's trying to draw ink and failing for some reason thus the dry whistle sound. When it stops whistling you'll have fixed your problem

    Reseat all the connectors and check that the clock / time is set correctly both in user settings and service modes. Firmware is up to 3.0.0 so what do you have on your machine?

    Re: Spear part

    There are multiple O-rings in the drum, have a real picture of the part you are looking for? I don't recognize that one. Or what's the problem with the machine?

    Take off the front and rear covers and blow out the dust, cut tie wraps and reseat connectors. That won't cost you anything, see what you see. If it still has problems you'll probably need parts...

    Re: master making ?

    From the amount of ink on the inside of the door and rails I'd also say your impression roller is probably caked in old dry ink. Can only scrape it off and clean so many times before you just have...

    Re: RP3700 Paper Feed Not Working

    Did you just try some scratch paper to test? Any chance the sep pad peeled back the underside of the lead edge of the 150 gsm paper so now it's fighting it. Turn the paper and original around 180...

  17. Re: Busted solenoids (lock, pressure) in my RA5900?

    Take 1 wire and lightly pull on it from both ends, then do it to the other wire. Like stretching out a rope. You are seeing if the wire is literally hanging by a thread inside the insulation
  18. Re: Busted solenoids (lock, pressure) in my RA5900?

    I believe that solenoid has 2 wires and a protective sleeve over it. Back in the day one of the wires would break at the U in bend. Cut off the protective sleeve and stress each wire and see if...

    Congrats. That plate can get a hairline crack in it as well. 99% of the mechanical stuff you learn on the RA is used in any Riso made in the last 15 years. Sorry and good luck

    Find a 255/305 or a 205c/255c or an FS-C8520/C8525
    Just swap 1 and see if your problem goes away and start troubleshooting. The entire ADF just lifts off once you undo the 2 thumbs screws and...

    Re: RP3500 Drum sticks wile printing

    Huh? The paper sticks to the drum? To much lead edge ink or the sep finger rubber O-ring is broken and not shooting the puff of air

    A better description of what's happening would help

    Re: Riso 790U

    Is it black or a color drum? If it's color how old is the ink and the last time it was ran. More than likely gummed up and not inking properly. What happens if you move positions of the drums?
