HP L260 Help

[Wilco]

Hello!
I took over a sign department at a small print shop North of Atlanta and I need some help with my HP L260 (previously the L26500).
I'm running some yard signs and the black ink is streaking horribly. I have cleaned the printheads, lubricated the carriage path but it still is streaking.
I'm using RIPCenter and I can't find how to change the media profile to increase passes to see if that solves the problem.
Any help with this would be appreciated.

Can you attach a picture of the problem?

The first thing I would check is to see if there is a piece of vinyl stuck under the carriage.

Also typing in the ip address of the printer in a browser will bring up the interface for the printer,
there you can see the status of the print heads to see if they are still under warranty.
That may give you an idea of how old they are.

You can also align the print heads from the touchpad.

Just increasing passess is not going to solve your problem. Unless your doing something like 6 pass and what you are seeing is banding and not streaking across the prints. Is it a uniform band? Or is the ink being scraped off. My first guess to the word streaking is like the first responder. Probably a piece of vinyl or something is stuck under the carriage dragging across the print. When you take the heads off and look down into where they seat. See if you can see anything down around the edges. Then check all around the carriage for any little fibers or vinyl. Then if that doesn't solve the problem post a picture of whats' happening. Most people can post pages about whats going on and it could still be 10 different things. Show one picture and you narrow it down a lot. The whole a picture is worth a thousand words

Here is what it is doing, only on the color black:

EDIT: I ran 8 signs successfully with no issue and then it progressively got worse. Originally starting on the left side prints but it has effected all of the prints.

What kind of vinyl are you using??

Looks like something dragging to me.

There is definetly something on the bottom of your carriage. That or the black prinhead is completyly out. When you cleaned the printheads were any of the edges of the bottom popped up. This will cause problems like this.

There was a tiny piece of vinyl caught under the carriage. It took some work but I got it out and it ran like a dream. Thank you SO MUCH everyone. Appreciate it more than you know

Also I can't really tell if it is the image or if it is the print There is stepping which is the print but it looks like there is a slight shadow. But you might benefit from a head alignment. This might be because one of your black heads is misaligned a little bit. Especially if you cleaned them and didn't run an alignment.

That print had been laminated and mounted on corrugate which is why it doesn't look so neat
