Composite printhead fire signals
View Patent ↗A method and device for providing a plurality of fire pulses in an ink jet printer, which includes a production of a plurality of fire signals. Each fire signal of the plurality of fire signals are asserted at a different timing than the other of the plurality of fire signals. The plurality of fire signals are combined to form a composite fire signal that maintains the different timing.
1. A method for providing a plurality of fire pulses in an ink jet printer, comprising:
producing a plurality of fire signals, each fire signal of said plurality of fire signals being asserted at a different timing than other of said plurality of fire signals; and
combining said plurality of fire signals to form a single composite fire signal that maintains said different timing, wherein each of said plurality of fire signals includes a prefire signal and mainfire signal, the prefire signal and the mainfire signal having varying widths; and
wherein further said step of combining comprises constructing the prefire and the mainfire signal widths with two respective pulses at leading and falling edges of each of the prefire and mainfire signal.
2. A method for providing a plurality of fire pulses in an inkjet printer, comprising:
producing a plurality of fire signals, each fire signal of said plurality of fire signals being asserted as a different timing that other of said plurality of fire signals; and
combining said plurality of fire signals to form a single composite fire signal that maintains said different timing, wherein each of said plurality of fire signals includes a prefire signal and a mainfire signal, the prefire signal and the mainfire signal having varying widths and wherein said step of combining comprises constructing the prefire and mainfire signal widths with two respective pulses at leading and falling edges of each of the pre fire and mainfire signal.
