Performing the backflush method with a syringe fitted to a tubing connected to the PC inlet port to suck up the windex the print head is sitting on, it is significantly harder to pull fluid up as compared with the other channels. Where as a light pull on the syringe immediately sucks up fluid from the other channels, the same amount of syringe pressure does not pull fluid up from the PC channel.

There definitely is blockage, but what I don't understand is that I did not experience this in my previous soak which cleared up the PC channel. Now, after 3 full color prints I previously mentioned, the PC channel is seemingly worse. Any ideas?
