Abstract
A printer with a media transport has a rigid, air-transmissive platen. A movable air-transmissive flexible web overlies the platen and moves along a feed axis. A suction device communicates with the platen to draw air through the web and through the platen so that a sheet of media carried on the web is biased toward the platen. A manifold underlies the platen and has a number of separate chambers open to the platen, so that the suction device is connected to each of the chambers. A controller operates to selectably prevent communication between the suction device and at least some of the chambers.
