摘要： An airflow device includes a motor to drive an impeller to cause a first airflow and a second airflow. A housing at least partially encloses the motor and impeller, and the housing defines at least a first path and a second path. Via the first path, the first airflow recirculates and is heated with the first path including a first wall with a nozzle array through which the first airflow passes to contact printed media passing external to the first wall. The second path receives a second airflow of air to travel alongside the motor and exit through a first port to join the first airflow at the impeller.

摘要： A printer mechanism includes a printhead to print on a print medium, and a platen located generally adjacent the printhead such that the platen and the printhead define a print zone therebetween. The platen includes a plurality of elongate ribs that project from an upper surface of the platen in a spaced relationship and positioned to contact a lower surface of the print medium such that the print medium bends downwardly between the ribs to provide an undulated section of the print medium with hills and valleys in the print zone. At least one shape control mechanism transforms each of the hills in the print zone into a corresponding valley in an output path adjacent to the print zone and transforms each of the valleys in the print zone into a corresponding hill in the output path.

摘要： According to examples, an apparatus may include a back panel to absorb energy and an energy emitter to supply energy onto a build material layer. The energy emitter may include an energy emitting element and an outer tube. In addition, a reflective element may be provided on a portion of the outer tube facing the back panel to direct energy away from the back panel. The apparatus may also include a transparent panel, in which energy from the energy emitter may be emitted through the transparent panel and onto the build material layer.

摘要： A printer including a print bar and a dryer system. The print bar operates to deposit printing material in accordance with a print job. The dryer system operates to intake and heat air from an internal region in which one or more electrical components of the printer are located. The dryer system directs the heated air through multiple outlets that are acutely angled with respect to a location or media of deposited printing material, to dry the printing material while cooling the internal region of the printer.
