摘要： A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a printhead to eject a print fluid through an opening of a carrier plate to a deposition region. The media transport device holds a print medium against the movable support surface by vacuum suction and transports the print medium through the deposition region. The air flow control system is to flow air through the carrier plate to the movable support surface via a port through the carrier plate on an inboard side the carrier plate and to control a flow rate of the air flowed through the port based on a size of a print medium transported by the media transport device.

摘要： A dross extraction system for a printer is disclosed. The dross extraction system includes an ejector defining an inner cavity associated therewith, the inner cavity retaining a liquid printing material. The dross extraction system also includes an inlet coupled to the inner cavity and a conduit external to the ejector having a distal opening, positionable to contact the liquid printing material to attract dross therein, thereby extracting dross from the liquid printing material when a negative pressure is introduced between an internal volume of the conduit and the dross.

摘要： A printing system comprises a print fluid deposition assembly, a media transport device, and an air flow control system. The print fluid deposition assembly comprises a carrier plate and a printhead arranged to eject a print fluid through an opening of the carrier plate to a deposition region. The media transport device comprises a movable support surface to transport a print medium along a process direction through the deposition region, the media transport device holding the print medium against the movable support surface by vacuum suction. The air flow control system is arranged to selectively flow air through the opening of the carrier plate between the carrier plate and the printhead based on a location of a print medium transported by the media transport device relative to the printhead.
