Abstract
An inkjet printer system includes a porous printing table and thereunder a vacuum chamber that may be divided into sub-vacuum chambers by a movable vacuum divider and a brush attached to prevent contamination and vacuum leakages in the vacuum chamber.
Claims10
An inkjet printer system comprising:
- a porous printing table;
- and
- a first vacuum chamber under the porous printing table to hold a substrate on the porous printing table;
- wherein
- the porous printing table includes:
- a set of air channels;
- a bottom surface including a set of apertures connected to one or more air channels of the set of air channels;
- the first vacuum chamber includes:
- a movable vacuum divider to divide the first vacuum chamber into a first plurality of sub-vacuum chambers, each of the plurality of sub-vacuum chambers including a sub-vacuum chamber controller to pull a vacuum through a portion of the set of air channels and to create a first vacuum zone on a top surface of the porous printing table;
- and
- the movable vacuum divider includes a brush contacting an inner surface of the first vacuum chamber and the bottom surface of the porous printing table.
