    The Ryobi 3304 recently purchased ( used ) for my employer has the worst watering conditions I have ever encountered in all my years as a press operator. I have ran large and small format 4 color presses in my career and I have ran this 3304 brand new in 2000- 2005 and it seems you cannot keep perfect water to ink combo. Especially start and stopping the press takes almost 100 sheets to get evened out. The water seems to drip in different locations on different heads as you run creating wash-outs in your colors - did everything from NEW METERING ROLLERS new INK FORMS cleaning with MRC - Chrome cleaning. The problem seems to be DRIPS - running water controls down to 2 - any higher makes it worse......does anyone have any suggestions ???? I also have great support from our local Techs - however unless we pay them to come in I cannot continue the STOCK WASTE .........also have a fit issue - taking to long and stretching beyond what I should to get my CMYK to fit.........THANKS...........Caddy the best press operator on the East and West Shores of the Susquehanna River in Lemoyne Pennsylvania.....................................HELP

    We find that aftermarket water rollers are basically garbage. The oem rollers are expensive but will run way better, especially the metering roller. Also I've had to turn down the water pressure coming out of the metal pan tubes quite a bit to avoid it forcing drips over the oposite edge of the pan.

    Hope you sort it all out.

    heres how I set are Ryobi dampners. First set the water oscillator with the form.(have to ink up oscillator using bridge roller no water)2.5 ml stripe. 2nd-waterform to plate. 4ml stripe. 3rd-water oscillator to metering roller 2.5 ml stripe. 4th-water oscillator to metering, open up until uniform all across. then close evening until no beading ,once closed even an extra 4 clicks each side.
    fit issues- even pressures all units, make sure the ink tensioning roller are clean especially on the ends. I keep my dampening solution very clean and conductivity below 1200. Hope this helps!

    Addressing the fit issue. I've run the 3304HA which has semi automatic plate loaders which if kept clean, lubed and zeroed out will give excellent register. If you have a press with old style manual plate clamps then stretching is going to be an issue especially with poly plates.

    like previous post said, get OEM metering roller and make sure you have the right plate, right means the rip has been correctly calibrated with correct output profile

    ABSOLUTELY MY FIRST THOUGHT when I saw the water levels and the horrible valves on the press that our water levels were to high.......and imagine this my co worker has been on the press this week and has little problems - - found out another associate replaced the VALVES giving us better control on water FLOW............WOW .......................and absolutely agree on water system sucks.........................I have run all types large and small format 4 - 6 color printing presses and this system was imagined to operate like a larger press and was never able to conform to that.......ie - stress....

    yea-manual plate clamps - try to avoid stretch as much we can..........also helps not to have plates come out all over the place = we even have to cut our own plates down to ( I believe its 450mm ) which doesn't help guess plates are on a roll......................ugh !

    OEM-Original Equipment Manufacturer. I've tried the aftermarket(syntac, lithoroll etc.) and they are hit or miss, usually miss. The OEM rollers are much more expensive but with the water system being the heart of this machine its worth the extra cost. The two water rollers cost just as much or maybe a little more than the rubber ink rollers per head.

    Check the metering rollers for end play, It would be worth paying your local tech support to come and sort all this for you.
