My 7900 is in PROK4 (the orange and green lines are dead and the cartridges are here in flush)
I just restored the K4 inks after a pause during 6 weeks. I had before done an init fill with flush cartridges, and everything worked perfectly before pausing.
Without starting a new init fill with the pro inks, I had a flush leak under the maintenance tank, when I started the 7900, while it is empty.
I just disassemble this part of the printer and I notice 2 things:
- Waste tubes to tank maintenance are almost dry
- The “entrance” of the green is totally red of flush.
As currently all lines are still filled with flush (except green and orange) would that mean that the problem could comes from the pump of the waste tubes? or “something else”…
Sometimes the x900 are really painful
