A page wide ink jet printhead body is formed using first and second series of identically configured rectangular piezoceramic blocks having widths not greater than about one inch. The individual blocks are poled in widthwise directions and secured to one another and to an upper side surface of a nonpoled piezoceramic lower body section. Horizontally equally spaced saw cuts are then made downwardly through the first and second block series, with the block width being an even multiple of the horizontal saw cut pitch, and saw cuts extending vertically through the aligned side junctures of each block series. A top, nonpoled piezoceramic body section is then secured to the top side of the second block series, the saw cuts forming within the resulting printhead body a spaced series of parallel ink receiving channels interdigitated with a spaced series of piezoelectrically deflectable sidewall actuator sections. A suitable discharge orifice plate is then secured to the body, over the front ends of the channels, and the rear ends of the channels are appropriately sealed off.
