    metering roller

    I open up both sides so there even, then tighten them evenly till no water bead and tighten about 7 or 8 clicks.

    We are running the same fountain solution mix that we run on our komori the damp systems are very close in style . maybe we should check it out . we are also building lots of ink on the metering roller in A short period of time

    dampners

    Do you use a chrome roller cleaner and desensitizer on the water chrome? I do whenever the press isn't going to run for awhile. Since doing this regularly my metering rollers are staying ink free.

    The wash up is key with these. We have the same Press. Don’t drop the water forms during wash up until the end. Also you may want to gum chromes each night to ensure they don’t get sensitive.

    Yes the rollercleaning is key on these 750’s. Have put on 70 mill. In 10 years only changed the form and waterrollers.

    I run dayshift only and use a chrome cleaner/chrome desensitizer every night. The metering roller stays clean.

    L&G,
    We recently bought the Ryobi offset press model 754 secondhand from South Africa .The press came with few electrical issues.We managed to fixe some such Fan's at Delivery Section. But We still have the issue on the ink roller cleaning solution circuit valves of all the printing Unit which is not working. When performing the automatic ink roller cleaning from PCS.However the ink roller cleaning water circuit is working.We can see water coming out from water nozzles of each printing unit. For the solution nothing is coming out from their nozzles.
    We checked the pumps they are all working ( the water and the solution pumps are woring ). We did the physical check of all the control box of each printing unit did not see any sign of damaged;
    We have electrical diagram of the complete system and we went through it but cannot see from which control box came the control signal of the ink roller cleaining solution valves.Please help to provide some toubleshooting guide and schematic showing the complete path of the cleaning solution valves control signal on each printing unit section.
