Hello List, especially folks with 9900 experience:
This is interesting. 9900 consistently producing perfect nozzle checks with flush fluid. New P Pro inks installed in fresh VTPhotoInkjet carts, and carts installed in 9900 using initial fill. No Warm VL ink in Orange Channel on nozzle check. One additional initial fill performed, no joy. Inspection of Orange Channel cart shows less ink than the level just previously filled to, consistent with other carts just installed. Removed said Orange Channel cart (and paired Green Channel cart), replaced both carts with respective flush carts. Performed 4 paired CL4 cleanings to see flush fluid now printing on nozzle check in Green Channel, no visible ink at Orange Channel. Inspection of lines inside printer shows flush fluid all the way to the print head for Green Channel, halfway up lines for Orange Channel. Performed 3 additional paired CL4 cleanings and now have flush fluid at print head in both lines as appropriate, and flush fluid printing in nozzle check for both Green and Orange Channel positions.
What gives ? Why can’t the ink be printed but the flush fluid can ?
Attached image shows (top to bottom) nozzle check after initial fill [no Warm Very Light ink], after the first 4 CL4 cleanings of paired channels [flush fluid visible only in Green Channel position], after additional 3 CL4 cleanings of paired channels [flush fluid visible in both channels as appropriate].
