  1. Re: RISO GR drums (and an SC5500 cable) wanted

    RISO does not make a metallic gold for GR. Z & F type ink, yes. BUT you have to order a whole case, 10 tubes. Also the shelf life is only 1 year.

    Good luck.

    Re: GR3770 & SC3000 shrinking artwork

    Is it the GR, the rip, or the file. Got to test different things to eliminate them. Does an image shrink when scanning and making a master off the glass? Do other files shrink when printed? Let us...

    Re: GR 3770 Timing Issue - Please Help!

    Shouldn't have used the button. Looks (but I haven't been in a GR for a long time) like the timing is all off. If you got a manual, follow the directions and pictures and get the main pull and cam...

    Re: Disassembling a GR3770

    I'm going to take a stab in the dark and guess you have the GR 3770 service manual. It only has the differences between the base GR and the GR 3770. The base GR service manual (also in separate PDF...

    Re: Disassembling a GR3770

    Find yourself a technical manual for disassembly. But specific parts I'd say the impression roller and the guide roller assembly. The impression roller is easy, pulls out with leverage. The guide...

    Sorry looked up wrong code. 20gauge is correct. Something with the ink tube set switch or generic ink.

    Re: Getting Round C53 Riso GR1700

    C52: the drum set switch is not depressed/actuated.

    Since you took apart a drum without a manual you probably to the plate to actuate the drum set switch on wrong or mixed up with the position...

  16. [Error Code] Re: GR3770: Elevator Locked -- Running w/o Paper Feed Safety Switch & Actuator Plate

    Yes you are definitely miss the safety switch. I see two wires with electric tape on them. Get a switch and plate (or something that will substitute) on, best solution.
    Otherwise see if you can...
  17. Re: Riso GR image banding/noise at intervals on side of prints (in master)

    It looks like the print pressure is uneven. If the impression roller is new, then the actual pressure applied is uneven. If you have a GR manual it's in there somewhere on how to check and adjust. I...

    Re: SC7700 RP/GR compatibility?

    The SC7700 is not RP compatible. A SC7900 is. So don't go looking for a GR it's not compatible either.

    The RP is also network capable with at RISORINC-net C card. Or B pending on serial number.

  19. Re: RISO 3750 drum carriage locked - no drum in carriage

    There is a solenoid release that won't actuate without a drum in place. But you can manually release it with a screwdriver, flat blade best. There is a slot just under the carriage. You should be...

    Re: RisoR3950UI

    If it's not the drum as ddude suggests and internal print is good, it kind of looks to me that the scanner settings are set to very light or the scan mode is a lighter setting. Good luck.

    Re: riso rz 220 stretched mark on paper

    I have seen a few different causes for this. First is often the paper, does it happen with a different ream? Second, impression roller needs replaced. Third, one-way timing gear. There is a tech...
  24. Re: Riso FR3950 doesn't make masters, covers entire page in ink

    Go into test mode and do an internal print (suggest check board) if it's all ink/black then something is wrong with the thermal print head. If is good then the scanner is at fault, probably the...

    Re: Duplicators vs. MFP's?

    RISO units can print large numbers at a fraction of the cost of a mfp. Also print on various card stocks and envelopes that many mfps struggle with.
