    Morning Guys, just wondering if anyone can help. Our roland has recently started to drop large amounts of ink randomly it seems, over our prints and along the edges. It doesnt appear to be hitting anything but cant think of what else it could be. Anyone had simular issues? :awkward:

    Have you checked round the head for fluff or hairs hanging down? These can cause ink to wick down onto material, but can be quite difficult to see. I usually get a very strong torch to check. It’s surprising how much ink they can actually deposit.

    Have you checked the dampers?

    List of things.

    Fluff…droplets form & drip.

    Damper / manifold issue (cracked & bleeding air or o-ring failure) so ink flows through to the head)

    If running bulk – over filled / a larger than expected ‘head’ of pressure.

    Thanks for the replies. There doesnt seem to be much if any fluff on the head.But whatever the issue, its still creating droplets on the head!!?? No bulk system running, just standard ink cartridges mmmm :rollseyes:

    Have you checked the capping Station at the other side? Ours decided one night that it was going to piss ink all over the place. When I removed the cover on the right in there was covered in ink. When I cleaned that up the problem disappeared and never occurred again thankfully
