I have been having issues with my dtf printer For quite some time now, my printer has been having problems printing white. I will run tons of cleans and nozzle checks, and the nozzle checks are always super erratic (the color ink is working just fine with perfect nozzle checks). There doesn't seem to be any consistency. Sometimes a clean will improve the nozzle check and sometimes it will cause the white ink to dropout all together. Even when I am able to get nozzle checks that are good enough to start printing, the white ink will drop out after about two inches and becomes extremely faded with significant banding. I have replaced the printhead and dampers. I have flushed the lines and cleaned out the ink tanks. Has anyone ever experienced this issue before?
