Same problem here

you need to replace the black print head.
here you can get it:

hello, you will need to run a cleaning cycle, you are looking for black printing, if not printing well, it might fail, if it does you will need #88 printhead. the black/yellow one. most times you will not need calibration to print, unless machine is stuck in that mode and won't pass. and won;t allow for print.
