Banding on new imagePROGRAF PRO-2600

[number8]

Hi,

I have a problem with banding on two new Canon ImagePrograf 2600. The banding is present in dark grey areas and is both running horizontally and vertically (see attached images).

I have done a Service Nozzle Check which indicates that 5 - 10 nozzles are clogged. 

I'm onto the second machine, it was replaced by Canon yesterday under warranty, and I'm still having the same issues.

Anyone with a similar experience or any idea on what could be the problem here?

What kind of paper is this? And what paper type and profile are you using?

This is with all PK ink papers including Canon Pro Luster. I'm using the paper manufacturers supplied AM1x files for media types and ICC profile.

What I'm seeing here doesn't look like banding. It looks like paper rippling as it's getting wet by the ink. But it doesn't look like a "banding" issue. What's strange though is that I can't imaging Luster doing that, unless it's really thin. I've seen this occasionally on matte papers and rice paper where the paper ripples with ink saturation. 

Sorry, that's all I've got.
