Can't clean printhead on Epson Artisan 835 - unable to force liquid through w/ syringe

I have an Epson Artisan 835 with what appears to be a clogged printhead- nozzle check gives me no yellow and half black. The other colours are mostly ok.

I have a syringe and plastic tubing, so I've been attempting to clean the printheads using this method with a mixture of ammonia, water and isopropyl alcohol.

No matter what I do, however, the syringe is unable to push any of the solution into any of the printheads. I push it until the pressure is so great that it forces the tub off of the cartridge spike. This same happens for the colours that are working.

Any thoughts on what I'm doing wrong or a step that I'm missing?
