This machine uses black pigment ink for text printing, and I use it accordingly. There's still plenty of ink. Total print count: 5310 sheets It's contradictory that the nozzle check prints well even though ink isn't flowing through the tubes, so it's something to watch out for. It's likely to run out of ink after printing a few sheets... It's in transport mode with the ink valve closed and the head fixing claw inserted, so please release it before use. Starting it without removing the claw will obstruct the movement of the ink head and cause error 5100. Please read the manual carefully before starting. I'd be in trouble if you said you wanted to exchange or return it because of an error caused by that... I will ship the main unit, power cord, and instruction manual in transport mode, packed in a bag + bubble wrap and cardboard. Please consider.
