Theory of Operation 2-29
The printhead’s jet stack is fabricated from a stack of chemically etched steel plates
which are brazed together to form the jet array. Channels formed by the stacked plates
route ink past the 1236 individual, piezo-electric crystal-driven diaphragms, which
force the ink in droplets out the 1236 corresponding nozzles. Looking at the printhead
face, the nozzles are arranged in 12 rows, in color order KYKYKYCMCMCM, where
K = black, Y = yellow, C = cyan, and M = magenta. During the printing process, the
printhead would only have to travel approximately 14 pixels horizontally to provide
complete coverage. However, the printhead travels much further, depending on print
resolution, to interlace each jet with the output of neighboring jets.
