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