Abstract
A media transport assembly includes a plurality of pallets arranged to circulate on an endless track through a print zone and a handling zone. In the print zone, the pallets are temporarily grouped together to support and move a print media during printing at a substantially constant velocity. In the handling zone, the pallets are spaced apart from each other as they circulate back to the print zone without supporting any print media.
Claims15
A printing system comprising:
- a plurality of pallets;
- an endless track on which the pallets circulate through:
- a print zone configured to temporarily form a group with some of the pallets in a position immediately adjacent each other and configured to cause the group to support and move a print media, wherein each pallet is smaller than the print media;
- and
- a handling zone configured to move the other respective pallets along the track while spaced apart from each other and return the pallets to the print zone.
