    Posted by Shawn Bentley on November 3, 2017 at 7:52 pm

    hi guys i have the EJ640 roland and I’ve just started getting some banding one the magenta and reds which I’ve never had before?, I’ve done a maintenance clean and a test print shows a couple of imperfections, also changed the felt wipers as well and cap tops look in very good condition. any ideas would be appreciated cheers in advance. ( just done another powerful clean and a medium clean on each head and the magenta still showing with those 2 gaps ?

    I would say having those nozzles out on the magenta is probably enough to cause this.

    Have you let the heads sit in some cleaning solution in the capping station to see if this will clear them.

    Fill the capping station up with cleaning solution once heads rest in the caps turn the power off and let the heads sit for a while.

    This has worked for us in the past.

    Or if you in warranty and can wait let Roland deal with it

    Hi Shawn,
    We have a VS 540 so different machine but I would imagine the process is much the same.

    We put the machine into a manual clean, but as soon as the carriage is out we turned the machine off at the back.

    Then opened up the cover and took the waste pipe from the cap station out, up at an angle and then taped so the solution can’t drain out. Then filled the cap top with cleaning solution and soaked lint free cloth in the solution also. The lint free cloth is to be chopped up to fit inside the capping station. This will make contact with the head.

    Then push the carriage with he head very gently back to the capping station till it clicks in place.

    We left for an hour and 24hrs. Both times a difference was made but in our case not enough unfortunately.

    Once time is up undo the process, move the carriage out gently, remove the cloth and put the waste pipe back in the drain bottle etc.

    Once that is done move the carriage back to the capping station and click in place and fire the machine back up.

    I would then put it through a powerful clean and hopefully anything that has been blocking the nozzles will of softened up. It may need a few powerful cleans and a bit of a rest as the solution can take out nozzles if there is a bit of it on the head.

    We lost half a head due to a head strike. We managed to get it back to normal with this bar 2 nozzles on the yellow just like you have. So we had to get a new head 🙁
