Abstract
A pressure regulation system for an inkjet printer includes a chamber for containing ink, a level sensor to measure the level of ink contained in the chamber, a pressure source for providing a fluid at a controlled positive or negative gauge pressure, and a pressure control device to control the pressure source. An ink supply regulating device regulates the flow of ink and an ink flow control device controls the ink supply regulating device based on an output of the level sensor. The pressure regulation system can be mounted close to the printhead.
