There are multiple variables and factors that go into this nozzle check failure. Hopefully we can work through them. Jon will email soon regarding ink as well.
First thing first. If auto nozzle check is on and you have a permanent channel fail (aka LC or any other temporarily clogged channel), turing auto-nozzle check off will not clear the loop. Basically if auto-nozzle check is performed and a cleaning is done, ANC is performed again to the point where “Clogged nozzles are still detected” shows up on the screen even when you are printing, this means a command has been logged into the machine such that ANC will be performed on the next nozzle check or black ink change or boot up regardless of whether ANC has been turned off in the printer settings menu. It’s an evil little gremlin that has persisted even through the most recent firmware version.
The way to clear this is to turn ANC off, turn the printer off, boot into maintenance mode and clear all ink parameters. This clears the ANC instruction lock. An ANC may still be done during black ink changes however, but will not stick into a permanent loop as long as ANC is turned off in the printer settings.
Bad cleaning assemblies and the ANC loop are a prime factor in head failures on this printer. I recently resucitated a printer at Latitude that was in this state (about a week ago) with PiezoFlush and Pro inks. We replaced the damper and cleaning assembly together and then did an init-fill with flush and an init-fill with Pro. Then 2 normal cleanings and we were set to go.
If you still have PiezoFlush, I suggest the reverse. After getting out of the ANC loop, fill carts, flush with PiezoFlush and check nozzles. I’m worried about the relationship between your dampers, head, and cleaning assembly as it is absolutely not normal for this results post flush. Jon will email you in a bit as well.
One question: where you getting random nozzle drops during pigment printing with this printer before your flush-sit?
Another, when the cleaning assembly was replaced, was the damper (ink selector) assembly also replaced?
And for confirmation: You did prime your carts after cleaning and adding pro ink?
