Abstract (en)
A channel structure for an ink jet printhead (10), comprising a channel plate (12) having a plurality of substantially equidistant ink channels (14) formed in one surface thereof, with dams (16) being left between the adjacent channels, wherein each channel (14) is covered by a portion (32) of a diaphragm (18) supported on said dams (16) and deflectable into the channel (14) by means of an actuator (28) associated therewith is characterized in that the diaphragm (18) is supported on the dams (16) through spacers (22) which define the exact width and position of the deflectable portion (32), so that larger manufacturing tolerances are allowed for the ink channels (14) in the channel plate. <IMAGE>
