Epson 7880 Initial fill failed at 99% - what to do?

Walker, Dana, etal
I am in the process of upgrading to Pro and did initial fill with flush to make sure everything was clean. It stalled at 99% for several hours. I eventually pressed the rt menu button and it started the initial fill all over again. Searching the forum I fund an article with instructions on how to cancel initial fill. It worked but I wasted a litre of flush in the process.

My question is can I safely do another initial fill with my pro inks without it failing or if it does how can I complete the initial fill without a lot of ink wastage.

Thanks for any advice.

Hey Bob. I sent you a private email this morning,

I suggest that if all the nozzle are working you simply print purge sheets (24x90) on Bond paper for each channel.
