Epson R3000 change blacks, low inks message

[TomV]

If your Photo Black ink reading is very very low on the chip and you switch your printer to Matte
Black, you won’t be able to switch back to Photo Black.

That’s what happened to me

Can I use a chip from another cartridge that is filled with piezo flush ? This cartridge is half filled.
Thanks Tomas
