PIXMA G7020 - not printing Cyan color

[sajjanj]

Tried cleaning & deep-cleaning several times, but that didn't help. Tank has ink about 75%. Many conversations here seem to indicate that G7020 is generally a printer with a bad design, but how do I solve this problem?

You should perform an ink flush.
