I have a canon mx860 and the pgbk is not printing. I have cleaned and replaced the printer heads, I have cleaned the waste ink pads, I have reset the printer, I have also downloaded and installed new software and yet still nothing. Please help. I run off MAC Yosemite.
Sorry it took so long to respond.
Nothing printed when I went to copy something on the printer itself. I tried a few variations too but all just trying the black ink.
I have initiated nozzle checks but not from the mac. I did one test print from the mac and yet neither the one from the mac or the nozzle check on the printer printed pgbk.
