Abstract:
A vacuum roller system and a method of operation the vacuum roller system can include an assembly of interdigitated rollers, and a vacuum system, wherein the assembly of interdigitated rollers is operably connected to the vacuum system to move sheets of media through a downstream dryer in a printer, wherein a vacuum is drawn between individual rollers among the assembly of interdigitated rollers so that the vacuum is distributed across a sheet of media and is split around the individual rollers. The spacing between the individual rollers among the assembly of interdigitated rollers is variable to vary the vacuum.
