SP300V Simply cannot keep black flowing from cartridge!

[Gubb]

Have changed the pump, the cap tops, the dampers & syringed them. Start printing and the damper drains... the black tube empties???

Simply cannot keep black flowing from cartridge...

Anyone have any ideas?

Have owned this since new, has worked flawlessly for near 7 years. It started printing grey instead of black, figured it was time to replace the parts mentioned.

Seems it will not hold its "prime" for lack of a better term.

May have a bad damper....check also ink line on the damper side see if it's tight also make sure damper seating tight on print head stem.

Had all new dampers, but turns out the black one had a pinhole in the clear film, thus losing its ability to stay primed.....wasn't leaking , but sucking in air.

Was near impossible to see, but tenacity and perseverance almost always pays off.

Glad the problem is solved...
