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?

Yes, still the same issue. It hasn't been resolved by Canon yet. The problem goes beyond the banding you see in the images, on certain darker images the print quality is just not what to be expected. Both my Pro-1000 and 2100 produces better prints.

Ink starvation is more noticeable in the gray areas. I assume the left pumping unit is not working properly, as there are not enough pumping cycles.
