    I have seen some issues. First is the new ink damaged in any way. I have seen them shipped and get cracks in the top of the ink tube. This will cause the ink pump to suck air and not ink. Is the inking motor turning? If not then it may be a bad ink motor. If it is turning the ink may be bad. A few years a go there was a bad batch of ink out there if it is old ink. Last thing there is a screen inside of your ink pump. If this is clogged with debris it also will not pump.

    Is there a way to access this ink pump filter without taking the whole thing apart? I have been buying up used drums whenever I can, and have discovered that at least 4 of them seem to have bad ink pumps. I want to try cleaning this filter before i give up on them.

    I purchased one of the tech manuals, and I have had a hard time locating it in the diagram.

    since you have a tech book run the test mode to run the ink the drum on a known good drum. listen for the sound of the inking motor coming on. take a drum that you think is not good and run it. if you do not hear the motor then the motor is bad. if you can hear it running then it is clogged

    so the problem was actually a dried out drum screen and the pump itself? Interesting!

    Hi Tim C. I'm glad to see you solved your problem. How did you go about cleaning the ink screen? Did you have to take the drum apart?
    I think I have the exact same problem and don't know how to proceed. Please kindly forward instructions on how to proceed to me via email: x.pat00@yahoo.com

    To teta30 I took a damp rag (water) and twisted it to fit in the Ink port hole and twisted it several times, it must have opened the ink screen, because right after that it worked fine and is still working fine.

    I very recently, for the firs time ever, disassembled completely into pieces the drum for RISO RA4050. I got the ink screen,/silk screen, the pump, motor, motor drive board, drum drive board, all apart. This enabled me to clean thoroughly all the messy ink in the unit.
    BEWARE :You need plenty of diesel or kerosene, rags, WD-40, overall, hand gloves, & overall. It is quiet messy doing the job, prepare to get dirty, a lot of patience is necessary. you may also need to cancel some of the day's engagement! BUT all in all, it was a very good experience, I learn t a lot about these drums, especially that they can actually be repaired.
