I removed the Epson carts and installed Piezo K7 carts for matte printing -preceded and followed by power cleanings.
Printout pattern (from nozzle cleaning) shows the 3d patch from the left with color of PiezoFlush, remainder of patches looks OK, different shades of black.
Carts PK and LLK are filled with PFlush, LLK flush level looks lower than in PK.
Am I dealing with a chip problem?
I’d appreciate your assessment and advice, thanks.
