A system, comprising:

• an ink tank of a printer, comprising a main tank and a feeder tank in fluid communication with the main tank, wherein the feeder tank is at least partially filled with ink;
• a print cartridge of the printer, comprising a nozzle plate;
• a tube to establish fluid communication between the print cartridge and a port of the feeder tank, the port at a lower corner of the feeder tank located distally to a center of mass of ink in the feeder tank, the print cartridge and the tube;
• and
• a screen disposed at an interface between the feeder tank and the port, wherein the nozzle plate is located below a free surface of ink in the feeder tank when the printer is in a first tilted orientation and the port is exposed to air in the feeder tank, wherein the screen is operative to provide a negative gauge pressure at the port.
