    [Misc] Green Riso Ink Not Drying

    Hi,

    I recently bought a Riso RP3700 machine and am having trouble with my green ink drying. I have tried 3 different uncoated papers and left them to dry for over a week in some cases. I have also changed the ink cartirdge because I thought the one I was using might have expired, but still getting the same problem with new cartridge. Whenever I rub (not excessively hard) the text on the page after printing it smudges.

    Anything else I could try to fix this problem?
    Thanks
    Charlie

      The new soy ink has problems drying- best bet is to look for some old oil-based product. Riso will not acknowledge the problem, yet many customers have lodged complaints to them.

        where would I be able to buy the non-soy inks?

        also is there another way to dry the paper if the soy ink doesn't totatlly absorb into the paper?

          Try a popular auction site. Any non original will be fine, same as I use.

            I have not found any good solution to this- my customer who uses his Riso for Business cards has had complaints even weeks after delivery- if you rub the business card, the ink will smear. If you can't find old ink, you may not be able to solve this-

              Take the shell off the drum and adjust the Doctor Gap smaller (.06-.08mm) with a feeler gauge. I don't remember what the default is supposed to be (probably .1). Also check the shell/squeegee roller gap. Smaller Doctor Gap will allow less ink to flow so it's not so wet. It won't be so bold either.

                I've always had the non-drying issue with my Riso machines as well. Is there the suggestion that the "compatible" inks we find on various auction websites are the solution? I've used Riso for a long time, but never tried the non OEM inks for fear that it might screw up the drums or otherwise produce unfavorable results.

                If someone has found a solution, I'd appreciate a pointer to a suitable supplier of oil based GR ink...

                Thanks in advance!

                  Like I said B4 get on the aution sites and buy non Riso ink. I've never had a problem and it dries better than some of the riso stuff. It won't cost an arm and a leg and you may even find some locally. One more point, I assume you have checked the exit fan is working, yes?

                    Good call, but yes the fan is working. I was only asking if you (or anyone) had better luck with any specific vendor than others. Unfortunately I just bought new Riso ink, so it might be a month or two before I can get to it.

                    Thanks in advance, my friend.

                      Virtually all the non riso are the same and originate from China. Non of them are soy ink so any will be better. Don't forget that you need to run it through for a while before it comes through 100% though a ream of paper will get most of it there.
