A novel encoder system adapted for use in print architecture at least
includes: a codewheel coupled to a rotating print architecture element; a
first encoder sensor mounted at a first position relative to the
periphery of the codewheel, the first encoder adapted to output a first
output signal; a second sensor mounted at a second position relative to
the periphery of the codewheel, the second encoder adapted to output a
second output signal, and the second sensor positioned substantially 180
degrees relative to the first encoder sensor; and a logic correction
circuit adapted to receive the first and second output signals, and for
outputting a correction signal with a period that is the average of the
periods of the first and second output signals.
