Forgot to Prime 9880 Cartridges

[J_T]

I accidentally forgot to prime a set of flushing cartridges. I inserted the unprimed carts and ran a charging cycle (I intended to clear the K7 Selenium out of the lines). I realized the problem once the cycle was over and I saw that the fluid level had not changed and that there was no piezoflush in the maintenance tanks. I immediately primed the carts and tried another charging cycle, but the printer won’t pull off the cartridges. I assume too much air was introduced into the lines initial to get proper suction. No luck with a power cleaning cycle either.

Any suggestions? Or am I out of luck?
