Piezoflush storage method

i am planning a trip away and I will be loading a 9800 and a 7800 with piezoflush filled carts. I thought that, instead of doing an initial fill, i could install the carts and continue to print with the ink in the tubes till the flush reaches the heads, thus not wasting so much ink. how does that sound as a method? Of course I would stop printing when it starts to show and then do a few cleanings or a power cleaning to complete the process…

I’ve done this before actually. Works ok. LLK will show the PF first.

best,
Walker
