Can anyone tell me how a 440ml ink cartridge signals the printer it has ran out of ink.
Does the lip that comes out touch a micro switch or does it send a signal from the chip.
I am having a problem of the ink finishing but the printer does not "Beep" or stop printing.
This is on a Roland VP 540.
Any help please.
