Abstract
In a printer, most of the motor drive applications are in relative motion. Often‐time though, it is necessary to
set a known Reference (usually re‐zeroing the position), for applications such as printing (zero against paper
edge), or for position limited mechanisms like the service station or carriage (zero against a reference
hardstop). For high precision paper motion, zeroing against a position on the encoder disk requires an
additional pattern, sensed by an additional sensor, to allow motion compensation against periodic positional
errors.
