Make sure the lines from the black/yellow channels are clear and the pump for those channels is working. You can swap the lines from the cyan/magenta pump with the black/yellow pump at the pumps and run a cleaning cycle to see what happens. After that, depending upon the result, since you have...

When you replace the dampers, you should always clean the manifold post with a foam swab moistened with cleaning solution before installing the new damper. I noticed what looks like some possible dried ink near the bottom of the post. This could lead to an air leak where the dried ink doesn't...

So, even if the ink configuation is set to CMYKM, the second magenta channel is not used during actual printing?

Correct. Also correct.

You should be able to push the captop up and down freely. It should also be sitting level. Are you getting any ink drips on your prints? Also look at the bottom of the head after printing and see if there is any ink on the head.

Read this thread. Just back them on a folder on your desktop. https://www.signs101.com/threads/i-installed-versaworks-6-on-new-computer-how-do-i-get-my-old-jobs-from-old-computer-to-show-up-in-the-queues-and-job-log-on-the-new-computer.175134/#post-1627309

Remove the station assembly cover, do a hard clean and watch to see if ink is going through the tubes going from the cap to the pump. You should alternately see ink and air. You should also see a slight gap between the print head and the cap at different times during the cleaning cycle...

There are times when it's good to be wrong! Glad it was just a damper and not the print head.

Are the captops OEM or after market?

The XR-640 doesn't have the option of doing this, like the Epson does. Once you decide to replace the head, I offer phone support for this printer and have done several head replacements this way.

Here they are... my internet sometimes gets really slow out in the country...

That is the key sequence Roland puts in their manuals by default. It isn't meant to be correct, only to mislead. I'll attach 2 files later. Having upload issues. Your machine will likely use the old sequence.

Where the middle pinch rollers can cause "print quality" issues is on softer or thicker media, such as banner, when the roller creates a very tiny impression in the media, which shows up as a visible vertical line the width of the pinch roller. This is caused by a tiny difference in the distance...

I need to see pics of the edges on both sides of the fill test, close enough to see detail.

Chris, See attached...

Print the fill test pattern in service mode. Watch while it prints and see if you have any obvious banding during the print passes. When it's finished, examine the both edges of each color, take pics and post them please.

Good to know! Thanks! So many variations...

Another thought... I would bet your printer and software are configured as CMYKW. This would be why you get the "shake ink" message. That is usually when white ink is involved. The other inks should only be gently shaken when installing a new cartridge, and do not need to be shaken regularly...
