    Hi everyone,

    Could anyone point us in the right direction of solving this problem, we're all of a sudden getting these black streaks / streaks of colour not cured on our printouts (see image).

    We've tried changing print-heads and the Ink Maintenance Kit so far but still getting bad results on the test print (see image), so assuming it's still going to print a job badly?

    Thanks for your help!

    That looks like the result of a bit of fluff under the head carriage, dragging across.

    Thanks for the reply Ian, how do you get under the head carriage to clean / check it?

    I would open the head cleaning cartridge door, and slide the cartridge out, and look from underneath.
    Or use compressed air when the head carriage is moved toward the bed a bit.
    There are a few things you could try

    Thanks, we had a look all looks fine, seems to glide along inside the printer fine too - reluctant to print anything else large as it's probably going to be wasted with a bad print again. Does the colours blending together in the test plot look correct to you, i'm assuming its not supposed to be like that?

    SOLVED

    Thanks for the replies, it turned out this part has dropped out of whatever position it's supposed to be in, and was physically scraping the print before it was curing. Doing a quick fix as a test, holding it up off the bottom, resulted in non-streaky prints again.
