Canon Pro-1000 solid block colors printing with gradient or banding

Hello,

I have a Canon pro-1000 which I use for printing graphic design assets on.

Often the prints are fine, but sometimes I get particular designs it struggles with - when there are large blocks of solid colors it will sometimes show a gradient as it begins or finishes printing the block.

Also, where I use an off-white background it will sometimes fail in sections leaving a banding of unprinted area.

I've tried doing a deep-clean of the print nozzles, aligning the print heads, wired and wireless connections.

The examples attached demonstrate this:

This should be a solid block of sand-color but it bleeds in to grey

Here the grey-bleed is smaller but visible just as the shape begins

Another view of the grey bleed

Here is some banding where the off-white background has failed right near the end of the print

Here's another example which should be solid green but has a gradient in to teal
