Abstract
A multi-channel fluid coupling for a printhead includes: a body having a first channel and a second channel, the second channel being relatively longer than the first channel; a first inlet port and a first outlet port at opposite ends of the first channel; and a second inlet port and a second outlet port at opposite ends of the second channel. The first and second channels are configured for proportionally modulating a flow resistance of fluids flowing therethrough.
