VP-540 problem

[EpicImages]

Hello everyone, long time lurker first time poster.

I'm in the middle of a large print job on a Versacamm VP-540 using Versaworks. I've printed 15 of the 30 8' signs we're making when at the end of the 16th print the printer started spitting yellow ink a bit.

I figured it just needed to be cleaned so I did that and now the spitting is gone but I'm getting slight banding. Before this happened there was no banding whatsoever. Anyone know how I could remedy this?

have you done a test print? go int othe menu and use the test print feature, see if any of the nozzles are misfiring or missing......you may have crap in your nozzles or on your head.

Yup I did a test print immediately after the cleaning and it looked like all the nozzles were firing fine.

have you cleaned the encoder strip? is the media clean? have you done a manual cleaning where you wipe down around the heads etc?

The media is clean and I did a manual cleaning around the heads etc. I'm not familiar with the encoder strip. Could you explain?

First fo all just do a feed calibration. Then check the cap-tops and dampers. Are you losing color during printing process?

Did a feed calibration and cleaned the encoder strip. Everything else seems to look ok. Still getting some slight banding.

I tried to get a picture of the weird banding. It's somewhat inconsistent in size now also.

Here is another picture of the lighter inconsistent banding. Is this ink dropout?

Could be ink dropout.....create square boxes of Black, Cyan, Magneta and Yellow to confirm droput.

another possible canidate....do you have "full width" scan enabled? if not enable it. I have seen werid color shifts/banding on long panels, when "full width" has been turned off. Having it off, prevents the heaters from getting media up to right temp, which in turn effects the dot gain of the ink drop.

if your still getting slight banding change your cap tops. there like $25 a piece so, $100 for all 4 so not alot. might help with the banding issue.
