Well, I've had about 1 week with our new Seiko. I've been able to print on Adhesive, Avery and other thin materials very well.
I am trying to print on vinyl banner and having some troubles. Both 13 oz single sided and 12 oz Avery double sided. I'm getting fairly bad banding. Any tips?? I was told not to raise the head height unless I was printing on 18oz or heavier banner. I've adjusted the media advance and run the built-in tests with no luck.
I have had some serious banding issues in the past and it sounded alot like yours. I could pause and clean the heads but after a few feet it would return.
This was the problem for me.
I had the printer enclosed in a room (for fume issues) I had 2 exhaust fans about 3 feet away from the side of the printer. Well these exhaust fans work good only when there is air for them to exhaust, ie with the door open, So to keep the room vented we would leave the door partially open. What was happening was that the fans was pulling air over the top of my print and under the ink heads and they were drying out fast.
Now I always print with the door closed.
Ohh and by the way I had to find this out the hard way by myself because my Seiko guy AND my distibuter are morons.
So just make sure that there is no draft getting under the heads while they are printing.
look under the carriage and see if you see any strands of banner material or dust/ink buildup dragging across the prints. This is a common problem with banner material because the fibers stick to the heads when loading the media (simple fix is to load the media after you have taped the edge with a piece of tape all the way this way it will prevent fraying and makes it easier to load before attaching to a core.
