I’ve been printing with the Piezo Pro inks on an Epson P9000 for about a year with no problems.
Recently I started getting the error message, Cartridge Not Recognized, for the Cyan cart. I pull out the cart and re-insert it to clear the error message, but then a print or two later I get the error message again.
How do I fix this problem? Taping shims on the bottom of the cart has not worked.
Is this a low (aka blinking) level cartridge chip?
If so that can happen. If not then this indicates either that something is off in the lock bar that clicks into the cartridge or the CSIC sensor is getting old.
