No, the TIJ systems can all be simply ‘turned-off’ at the end of a shift. Removal of the cartridge is a simple operation with a click-in/click-out and even if the systems are inadvertently shut-down, for example, there is loss of power to the line, no ink will be wasted or ejected, causing no detrimental effect to the ink solution or printer. Once power is restored, the systems all perform a quick software check, read the cartridge and then reset themselves ready to continue printing.
