CARRIAGE DRIVE SYSTEM FOR A SERIAL PRINTER WHICH MINIMIZES REGISTRATION ERRORS

摘要

A carriage drive system for use in a serial printer includes a carriage (12) movable in a transverse direction (52) across a print medium. Each of the transverse directions (52) is substantially perpendicular to a print medium feed direction. A print cartridge (26) is releasably mounted on the carriage (12) and has at least one printhead (34). The at least one printhead (34) has at least one ink jetting nozzle (48) for jetting ink. The at least one ink jetting nozzle (48) cyclically jets the ink at at least one jetting frequency. A carriage belt (14) is mechanically coupled to the carriage (12). A transverse drive system (16) drives the carriage belt (14) in the transverse directions (52). A drive motor (18) is coupled to the drive system (16). At least one cyclical disturbance exists due to the operation of the carriage belt (14), the drive system (16) and/or the motor (18). The at least one cyclical disturbance has at least one disturbance frequency. At least one of the disturbance frequencies is an integer multiple of the jetting frequencies.
