Systems, methods, and software to provide document management system user interfaces to clients. Each SLM receives light of a different primary color, which it modulates to form images for that color. The microfibers are individual filaments having an average length of less than about 1000 \u03bcm. The controller uses the outputs of the linear transducers to determine the linear velocity of the advancing first chuck and synchronize the linear velocity of the first and second chucks. The magnetic element support further includes a transition section between the first and second plate sections.
