Calling all Roland Experts - HELP

[phototec]

Ok all you Roland experts, what do I need to do to fix this issue, I have not seen this before?

I have a Roland SP-540V and get this overlapping pattern when doing a test print, it just started doing this.

Open to any and all suggestions....

Are you having printing issues?

Are you having printing issues?

Well, not really.

I noticed some slight banding on the last banner I printed.

What causes the test print to over-lap as shown in the photo?

That looks to be printed on PVC banner media. Banner media is relatively thick, and this thickness causes the need to perform a media feed calibration on the media. This will vary the distance of the media advance to account for the media thickness.

This calibration is performed on the printer itself.

So if you use the right profile when sending print to the banner material it should adjust the feed rate for the thickness?

Once the feed calibration has been performed, and the desired value identified for that media, it can be set in the media profile or on the printer via it's control panel.

Ok, I did a cleaning and loaded Oracal 3165G to do another test print, now it looks worse?

So, the material thickness (distant of travel for such a small image), didn't make much difference in the overlap.

Do the calibration with the 2 small squares on top of one another. One square is bigger than the other, and it is about 3/4" or so. You change the values so where the squares meet it is perfect. No overlap, no gap.

Let me know how it works out.

The second image has two nozzles out in the Magenta head.

Did you run the Feed Calibration as previously described? I refer it as the 'T' test, and the goal is to get crossbar and vertical stroke to merge as seamlessly as possible into each other on the media in question.

You need to do a Bidirectional head alignment. If you look in your manual it has the instruction on how to fix it.

You have to do feed calibration for every material that you run thru your printer before you start printing.

it actually looks better on the 3165 - still not perfect, but see how the 2 passes are farther apart (read: not overlapping) compared to the banner one?
