Abstract

An ink supply system including a reservoir and a foam regulator. The reservoir is configured to hold a volume of ink and configured to be in fluid communication with a fluid ejection structure. The foam regulator is operable in a first state in which the foam regulator permits application of negative pressure through the foam regulator to apply negative pressure to the fluid ejection structure and to the reservoir, and a second state in which the foam regulator blocks passage of ink foam through the foam regulator.
