Hello all and Happy 4th. Id be grateful for any help, Im having a heck of a time with this printer. I bought a slightly used VS640 to replace my XC540 and been having issues. I think air got in the lines from transporting it and having major nozzle drop outs in all colors. Its like I will have a perfect nozzle test print and the next one terrible. I normally just give it a few powerful cleanings and its back to normal for a week. This time 3 colors went out completely so I did a head soak then used a syringe and now all colors completely out and just blank test print. Any thoughts on would could have happened. The funny thing its even though a blank test print, the cap top has full color and during cleanings is sucking the ink thru the cap tubes to the pump so ink is going thru it, so why wouldn't there be some sort of color coming out in the test print. Thank you again for any help in fixing this to get me back up and running
