Abstract
A vacuum roller system and a method of operating the vacuum roller system can include a group of vacuum rollers operable to move a sheet of media through a dryer. The vacuum rollers do not require a vacuum to be drawn between the vacuum rollers. Each vacuum roller can include a plenum operable to direct the vacuum to a top portion of the vacuum roller to drive the sheet of media from one roller to the next roller. The plenum can engage vacuum holes in a rotating vacuum roller when the vacuum holes in the vacuum roller are aligned with the plenum.
