Possible loose ribbon cable or dirty cap station...
First, power off and unplug. Then take of the front covers to get into the printhead area... check to make sure the head ribbon cables are secure into the board slots and also into the head itself.
Uncap the head and manually clean the cap station. The black rubber seal around the edge of the sponge area.

How long have you had the VS-640? Call the tech to see if he can do a Warranty Service Call.

located in Norfolk, Uk hope its not the head
no scratches or jams to report i always run with the head in the high position.Try to do this:
-use a bag clip like this and pinch the pump tube (between the cap pin and the pump)

-when tube is pinch put cleaning solvent in the capping
- replace the head on the capping with the solvent
- wait 5 min and loosen the clip
- perform a MEDIUM cleaning
- retry the test print!

looks like a cap top issue to me. Make sure all of the tubing is clear from the captop to the drain bottle. i replaced a cap top a couple of days ago that was clogged and started the printer back up to find that the drain line from the pump to the bottle was clogged. It blew the endcap off the drain line and sprayed ink all over the inside of the machine. A 30 minute job turned into a 3 hour job to get everything cleaned up.
Bottom line, check all tubing lines before saying it is good.

thanks for all your ideas. i am trying the overnight head soak. I have clamped the captop pipes and filled the captop to the brim with cleaning fluid and manualy parked the heads with power left off. Will see how things are in the morning.

I head a head crash on our 640 and the test pattern was all over the shop.
Reinstalling the firmware fixed the problem.

did a full firware update today and no change in the nosle pattern. after i did the overnight head soak there was an improvment in the test print then after i did a short print job i just thought i would check the nosle patern and im back to square one

Keep in-mind the scratch (if there is one) will be at the very front of the head, not the middle as it appears in the print...

Thank you for pointing that out. i was aware that it would be closest to the front left when i looked, i used a microscope camera. Looks as clean as a whistle.
