P.Flush carts and chips

If I remove the ink carts and replace them with piezo flush carts in the proper slots (no printing planned for a few months) do I have to swap the chips as well- the recessed ones and

the outer ones? I suspect I do but like know what the experts suggest.

Thanks in advance.

Yes, you do need to swap the recessed chips to use the PiezoFlush carts.

The PiezoFlush carts should be used exactly like normal inkjet refill carts on the 3880 (with the OEM chip below and control chip above) on with flush fluid in them and not ink.

all the best,
