    Are you feeding the vinyl back words after the print to get the black media arms wet with ink. Or Dirty Media arms?

    almsot looks like the rollers are pinching to tight, and leaving indentations in the vinyl then when it gets printed on it shows like that

    What is the feed direction (left to right) (top to bottom)


    Can you explain the issue a bit more in detail?

    I see some marks on the media but with out more info... I'm lost

    sorry, it was in my other post. I am getting small little marks of all the colors. Look like calibration marks all over the prints. These are marks the machine is telling it to fire. I thought it would be the encoder strip and replaced that. Still getting the marks.

    Have you done any maintenance like a head replacement? could be a voltage problem.

    I can not tell what direction is the feed from you pick.

    Can you post a pic of a nozzle check? I'd like to see the head alignment.

    I know exactly what marks you are talking about. Have had the same problem.

    Two little lines about 1/8" apart then two more about an inch from them, Right?

    I'm not sure but I think your on the right track with the encoder strip. I had the same problem. I would try cleaning the encoder strip (even though it's new) With alcohol. Take the top cover off and use a sft cloth and really clean it good! Obviously being careful not to scratch it! I would also see if you can get to the sensor that reads the encoder strip on the head carriage and clean it also (i din't do that to mine, so I can tell you where it is.) It took several cleanings for mine to quit making those marks. About that same time I switched to Ultra inks So I was never real sure of the source of the problem.

    I have a outdoor Jr. and run it over my office network and my support kept telling me it was a network problem with the router i was using. They told me to run it directly on Parallel cable from the comuter but I never got that far to try it. I didn't think it was the network because the marks were always in the exact same location on the vinyl each time.

    Just two weeks ago i change the capping station and pump had everything all tore apart and when I put it back together the first print had those lines. But it never happened again. So I'm keeping fingers crossed.

    Hope this helps!

    Do you use flexi?

    I also started using Random Diffusion Dither pattern in Production Manager. Takes slightly longer to rip but gives much better results especially on Vecor images. Sometimes even error diffusion.

    Also see if it makes a difference if you run in unidirectional or bidirectional. I started running unidirectional about the same time the problem stopped. I know it takes longer but if it solves the issue at least you have something to tell Mutoh as to what the problem is.

    What printer is it?

    C lean your wiper blade at the service station its black because it's mixed ink. They seem to to me to be a head strikes. Check or reset profiles as well as cleaning the wiper blade. Head hight??? I can't seem to believe misfires that out of place.

    Not head strikes nor a dirty wiper, it is something telling it to fire. We got a work around, but gotta get it fixed. We have cleaned the encoder, replaced the encoder, cleaned the sensor. checked all conections etc. i'm kinda leaning to the heads, but not sure. It's a falcon outdoor 6 color.

    Thanks for the help everyone. If any body has any more ideas (besides buying a JV5) PLEASE let me know.

    I had those lines and found that they were eliminted for a while by unchecking the "Microdot" function in driver options. If that does not correct it, it might be a bad head. I have since replaced the head and the issue is gone completely now. A friend of mine has some of the lines from time to time and thinks they could be static electricity related.

    I have the same machine. I had the same same same exact problem for a long time. We replaced the clear strip at the top of the carriage (T-fence is what it is called, about $150 from sign warehouse). It fixed it completely. In the alternative, you can flip it over and reinstall it...may buy you some time. I have other problems with this printer, can't get a consistently good print for very long on vinyl. Prints beautifully on banner material.
