ABSTRACT:
A wide array ink jet printhead for use in an ink jet printing device and being capable of propelling ink to create a line on a recording medium in the device. The printhead includes a plurality of adjacent and generally linear printheads each having a first and second end ink jet. A plurality of electrodes are in communication with the ink jets. A microprocessor controls the electrodes to selectively provide a current signal representing digitalized data to the electrodes. When the digitalized signal is intended to create a line on the recording medium more than one printhead wide, the ink jets on adjacent printheads forming the line are initialized from a first end ink jet to a second end ink jet on a first printhead and in a reverse order from a second end ink jet to a first end ink jet on the adjacent printhead, the sequences commencing substantially simultaneously on each printhead.
