SP540V: Banding in vinil high speed
Hi members,
i used to read and learn, but now i have to write for help. We used to print only in HIGH SPEED (HS) mode, but since last month i noted some banding in our vinil. And in this time we never changed our hardware or conditions, it still the same.
Today I ran a test and discovered that in STANDARD (S) the banding disapeared!
TODAY:
I’m using Avery MPI3500, with Roland ICC profile, EcoSolMax original ($$) inks. I’ll show some images to ilustrate.TESTED:
Unidirectional -> banding
Bidirectional (default) -> banding
HIGH SPEED (default) -> banding
STANDARD + Bidirectional -> NO bandingI could run my files using STANDARD, but it will take too long. Any advice? I cleaned everyday as Roland manual says. I have already cleaned that "flat transparent stripe" that goes beside head, which caused some disalignment (sorry my english!)

Not much help but I run High speed 1000 speed on head setting and dont have this problem, have you printed a head test print
thanks rich -
We have a VP540 and get the same problem when we do prints with 540×360 dpi. So I’m also interested in hearing any possible problem solvers.
-
The only media I have had the most problem free using high speed setting’s is MD3 and MD5 no problem what so ever but mine is only 760mm
sp300v which could make a little difference

we use avery2000 with no problems, never tried 3500
and your heads are fine?
Think the left side of the blue is where you started and the right side is where u cut it off… so your blue was good until near the end.
might be dampers, ink maybe running out in the plastic bit above the head on the cyan.

Take a photo of your test print up close and post it. We can tell if your heads are all firing and if your feed calibration is setup correctly from it.

Curiosity question have you updated firmware recently?

KEVIN: no, I didn’t updated my software or hardware. We never moved our printer. Nothing changes, only that for a month ago I noticied this behavior.
SIMON: we used to print in 3M Scotchal Plus, Plus II, D1000 and it was flawless! Even in this Avery MPI3500 it was perfect, until some time ago! Now, whichever vynil I use, I get this lines. In banner this banding don’t appear.
I use Versaworks 2.7 and now upgraded to 3 (this week), but I ‘brought’ this problem in 2.7 😕
Here is image i take 5 minutes ago. It’s end of day here (7:25pm) and my day was so slow (standard).
Now I can see that my CYAN is getting DARK. Do a CLEANING and this is the result side by side (PRE-CLEANING and POST-CLEANING).
Also my calibration is set to +0.15% to vynil (banner is +0.60%), my heads are aligned (ADJUST BI-DIR) and I hope they were fine, because my sp540v is only 08 months old.
IMAGES
First: I was off for a couple of hours and when i come back the printer was in standby mode, so I press ENTER key and do a TEST PRINT.
Second: After the wrong results, I do a CLEANING and a TEST PRINT. OK!!
Third: my CALIBRATION.

They look fine. Feed Calibration looks around right too. Not sure. I never could print at hi speed on our SP.

Have you tried printing an old file that you know was ok at high speed and compare it. It may be a problem with that file.
We had a cadet and that was what happened several times when the head went but judging from your test print that seems ok.
We now have the same set up as you and this does happen sometimes but a manual clean normally cures it. We normally print at standard as high speed is not that brilliant on some files. -
ahh… is your cyan and black a shared head like on the JV3? ours does this sometimes. Looks like lack of suction i think, the head clean forces it to clean up
I think I resolve it by swapping pumps around (or tubing) and the problem transfers to another set of heads (if it does e.g. swap cyan tubing with magenta and see if magenta starts struggling with the yellow
actually presuming you have a clean around where the head meets and with you have clean rubber rings, no dried ink etc?
-
I agree with Dave, think it could be the pump as had a similar problem on my cadet with magenta/yellow. Good news if it is the pump is it is easy to change and not very expensive.

are you using a bulk feed, check the ink levels in cyan and black are similar, sometime the if there is a lot more black than cyan the different pressures can cause a the black to suck into cyan etc.
-
yep agreed seen this on a cart with only a few ml left and a full cart in the second colour

We get banding on our SP540V when printing in draft mode – particularly with blues and yellows…The main reason is that the heads spit out the ink in the reverse order on the return pass (The new epson 4C heads seem to have overcome this judging by what I have seen in output from the new Mimakis).
Changing the dampers to the large ones has improved the banding issue a little (remember the 540 is really a supersized 300) so I guess having a minuscule more ink pressure helps. Sometimes doing an environment match helps a little too
But at the end of the day, if you are printing in fast mode … the sign is going to be short term/budget…so you gets what you pays for and banding is one of the xtras and no extra charge!!!

After a week, Roland contacted me (!!) and a technician told me to use profile "GENERIC VYNIL II-B"
Other configs:
QUALITY
HIGH SPEED
DETAILS: Interpolation (Bicubic)
Direction: Bidir (‘if you want more quality, try Unidir’, he saids)
COLOR GESTOR (mine is portuguese): Personalized / Custom
Raster(I) AND Vector(D): Colorimetric
Mark two boxes: Maintain primary colors AND Use ICC profileThis config led me to the old good HIGH SPEED, but it seems to be less vivid colors (if compared to our ICC Avery MPI3500, MPI3010, MPI3000).
I’ll retry contact Roland tomorow and I’ll post if anything new happens.
thanks dudes!

Had this problem on the Mimaki and Rockhopper. Both times it was the pump.
