Piezo flush to store 4800

I have an Epson 4800 I would like to store for a while. (I picked up a 7800 I am switching to and will order carts for that.) Is there any way to empty/use my current 4800 inkjetmall carts with piezo flush, or do I need new carts? (I plan on buying new carts for my 7800 but don’t want to have to buy an additional set for the 4800 unless I have to.)

Yeah, You can empty the carts, wash with distilled water, and fill with PF. Once they have PF they will never want to go back to ink though.

best,
