Abstract
Disclosed herein is a technique that enables a carriage printer to reduce precision in a media conveyor by improving mobility of the carriage. The carriage includes a mobile jetplate that adjusts the position of the printheads within the carriage. The mobile jetplate includes multiple motors that enable shifts in an axis matching the axis of the media. Operating the motors of the jetplate at different locations or at different intensities causes the jetplate to skew and achieve mobility of multiple axes. A set of sensors monitor media skew and shifts of the mobile jetplate are able to compensate for that skew. An additional set of motors shift the carriage to compensate for deformation of the beam that the carriage shuttles along.
