Need Help line on print

[miki rurki]

Hi,
When I print on my Roland sol jet xc540 print & cut, I have some line on print, maybe I need calibrate print head, or something? Test print is ok. Inks is on low level, but can print still. If you look closely you can see it? Print is bi direction.
Has anyone had similar experiences?
Veru best,

When you say test print is "ok", is it perfect?

Does this happen with all profiles? If you print on a higher quality setting, does the banding go away?

 

[miki rurki]

Testprint is perfect and print is on high quality print 720x1440dpi.

That's what I would have said (RE: Miki), go to your highest quality setting. But if you are at it, then check the print where it starts printing, Is the print perfect at the beginning but starts streaking more as you go down? If so, then it could be an ink flow problem.... (is there a slower setting?) or I see there is a color gradation. It looks like there is more magenta as you go down. Maybe one of the colors has a clogged nozzle that only shows up in certain mixes? Look at your nozzle check output really carefully.

Are your temp settings high enough? Can be caused by pooling, if you say your test prints are perfect.

I have better result, not perfect, but much better. Part off noozles on the one head, for some reason, does not work propperly. (Probably bad cap. Cap is new but not original, good copy, but little smaller for few microns then oem.) After pooling out ink through the head on the end cap ink tube with a syringe, and manual cleaning, i have better result. Tnx all of you for suggestion? By the way, Does anyone of you use not original parts? What are your experiences?

material what?

material what?

I think they wanted to know what material you were printing on. I have noticed on my printer that if the surface isn't completely flat, the colors display differently because of the different angles of light.

You say that test print is okay. Does it mean that there are 100% of nozzles and literally all of them fire creating perfect rows? Presence of nozzles in test print is not enough. On the other hand it might be improperly configured bi dir, feed rate or head slant
