Hello, and I hope you are all well.
This post has the meaning to collect some ideas because I run out of them.
After 3 years of not intense but gentle usage of the 3rd DX7 printhead replacement of my VS-640 (Other 2 printheads replaced for the same reason: Light Cyan deflecting / misting) I had missing drops in Light Cyan and gradual disappearing - till total missing - Black, so I've decided to replace dampers and the one month old captop - just to be sure that they were not the problem. (All parts and ink are always OEM and the printer is clean, in factory shape and look).
After "by the book" parts replacement, I did a power clean and some test prints. Again, missing lines in Light Cyan and not a single line of Black.
So I did what the "book" says after damper replacement: a Choke Clean. While in Choke Cleaning procedure, the Yellow and Light Magenta
plus the White & Metallic (were replaced some years ago with cleaning fluid) disappeared from flowing.
Only Cyan and Magenta left in captop. Some power & medium cleanings followed, no result.
I used two syringes to suck ink from the captop lines, ink flowing smoothly
but again, 2 channels only - Cyan and Magenta.
I know that a broken print head can loose many or complete ink lines in test print, but no ink flowing in 6 of the 8 channels?
I know that Choke Clean is not the best practice for a printhead but is it possible to block ink channels?
Any ideas about this?
Thank you.
