Canon Pro 4100 -Cyan in the photo gray- nozzle check

frauleinschmidt — Thu, 07 Apr 2022 19:15:32 GMT

Occasionally a gradient of cyan appears at the beginning of a print, and gradually fades out to the normal color. When this occurs and a nozzle check administered, there is cyan appearing in the photo gray grid, group 1.

In the image the contaminated gray is pictured on the left, normal nozzle check on the right.

This happens almost daily.

Does anyone know if this is a head issue, or some other problem?

Any commiseration or help is greatly appreciated.

Thanks, Krista

I am having the same problem on a pro6000, but with the 3rd channel. When I went to manually clean the print head, there were large droplets on the head, after cleaning, they came right back. I think the head is leaking, creating the droplets, which are either extending/bleeding onto other colors around it and contaminating them until they spray enough to clear out the contamination. I also see random color spots on prints from time to time. Based on the shape and size, I think it is the pooled droplets falling off the printhead during printing.

Check this image. Multiple proofs. You may change the head.
