Question Roland SP-300 Ink Pump question

    I was just reading the Manuel for my SP-300 and just wondering if I am reading this correctly.

    It say's "you can connect either tube from the cap tops to either tube of the pump"

    Thanks for your help Jim

    yes thats correct. the input of the pumps from the captops is a 't' fitting and it dosent matter which captop goes to which side of the T

    CS Service7 Repair:

    I am talking about the two T fittings that come off of the ink pump. One is on top and the other is on the bottom.
    Does it matter which one of these fittings you connect the hoses from the Y fitting to?

    I don't understand which way the ink pump is pumping. I thought the ink pump sucked the ink towards the ink pump and into the drain bottle?

    This is exactly what it say's in the Roland Manuel for the SP-300 "you can connect either tube from the cap tops to either tube of the pump"

    Kind of confusing. I have always connected the cap top tubes into the Y connection and then into the top T fitting that sticks off of the ink pump.

    think the confusion is the manual is referring to the old style pump which had 2 input and 2 out unlike the upgraded pump 1 in 1 out just a thought

    yes the pump should suck from the captops push to the waste the case of the new type is marked with a direction of flow arrow

    Woolly:

    Thanks for helping me figure out the correct way to connect the hoses because I am thinking I did it the wrong way.
