Abstract

Methods or apparatuses for correcting errors which can occur in allocating drive waveforms. The method includes provisionally assigning, based on input pixel data, each fluid chamber within said array as either a firing fluid chamber or a non-firing fluid chamber so as to produce bands of one or more contiguous firing fluid chambers separated by bands of one or more contiguous non-firing fluid chambers. Subsequently provisionally assigning, based on the input pixel data, each electrode the firing fluid chambers at least one of a first drive waveform and a second drive waveform; wherein the first drive waveform and second drive waveform are different drive waveforms. The method allocates, to each electrode of the firing fluid chambers, one of the first drive waveform or the second drive waveform. Identify where, the provisionally assigned drive waveform does not match the allocated drive waveform and correcting the provisional assignment of the drive waveform to correspond to the allocated drive waveform.
