Hi Tim,
Thank you for using the Support Forum. Unfortunately there is not a mode to allow black printing when black ink is low or out. Please consider contacting your support centre for further assistance.
Hello there,
Our Colorqube 9303 is extremely low on black ink at the moment and might run out before the shipment comes (set to auto-replenish).
Is there a "emergency" function where it can use the color inks to simulate black and white?
Thanks!
