I came to the fork in the road where you have to run a power clean cycle to get some air out of the lines. I swapped out two dampers and reassembled
the print head, did a test print and a regular cleaning cycle or two. The magenta cart was low, so I put a fresh, new refillable cartridge with Cone Color Pro
ink and proceeded to power clean. During the pwr cln, the new cart symbol on the printer flashed, so I reset it, then two other carts blinked, reset them, then
magenta cart blinked again. Since the 4000 allows you to turn off the ink counters, I did so. When I resumed Power Cleaning, it went on and on, and on, much
longer than usual. As the ink levels disappeared, I turned off the printer. Subsequently, even with computer disconnected, the printer keeps asking for ink levers
to be lowered or raised over and over and only gets to about 10% before up and down with the levers. I found a page on the Piezography website for this, but the
options in the self test mode don’t look the same or offer parameter changes from what I could discern since the pwr cln cycle interferes with scrolling through the
menu.Presently, I have the 4000 unplugged and will pause before getting back at it. Thanks for any suggestions!
