The VM channel on my 7880 is showing some pretty aberrant behaviour: it’s wildly out of register, to the point where it’s printing ink dots in the white borders of my prints, where there is zero print data, but also ‘bleeding’ into areas of subject where no M ink should be printed.
I’ve tried all the alignment tools, both via the menu on the printer itself and via Printer Uitility, without success.
Has anyone seen this kind of behaviour before? Do you think this is recoverable? Or is it time for a new printhead?
Here’s some details pics of test patterns, and an actual image.
