Question Roland SC545EX - Curious Case of The Disappearing Yellow

Hi Guys - having a weird issue here.

The yellow ink on the SC545 prints well out of a relatively new printhead (few months old).

Every morning when I try to test-print, yellow test lines are about 50% missing. Cleaning doesn't help. What helps is sucking some ink with a syringe from the plastic tube going from head parking to the pump. If I suck out about 5 ml of ink, everything works.

But the next day it repeats.

What could be the issue?

Thanks in advance!
