The present disclosure relates generally to printheads.
Inkjet printing creates images by propelling ink droplets onto a medium. An inkjet print head includes an array or a matrix of ink nozzles, with each nozzle selectively ejecting ink droplets. The number of operating nozzles and the drop volume establish the ink flow from an ink reservoir or supply, which may be an intermediary ink tank placed in close proximity to the print head or a remote ink tank. When printing average density images, the print head tends to consume steady amounts of ink. However, sudden changes in ink consumption often occur at the beginning and the end of the printing process. The energy used during an ink firing event may create motion of the ink in the firing chamber and ink delivery system, which may cause fluidic interaction between neighboring ink channels. When the interactions are large enough, crosstalk may occur, where the firing event of one channel may cause a disturbance in neighboring channel firing events.
