Abstract: An apparatus for mitigating noise in a printer can include a plate having a plurality of holes distributed across the plate and extending through the plate. A portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across a given frequency band and another portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across another frequency band in a media path of a printer. The apparatus further can include an acoustic baffling material to cover the plate and that can be configured to dampen the acoustic noise across the given frequency band and the other frequency band.

Abstract: An apparatus for mitigating noise in a printer can include a plate having a plurality of holes distributed across the plate and extending through the plate, the holes being dimensioned and configured to mitigate acoustic noise in a printer. A mesh material can cover the plurality of holes, wherein the mesh material can increase air flow resistance through the holes and thereby facilitate removal of acoustic noise from a media path in the printer.

Abstract: An example apparatus includes a main body and a tray. The main body has a first wall, a second wall and a connecting portion. The first wall, the second wall and the connecting portion form a cavity, and the first wall has a recessed portion formed at a front end of the first wall. The recessed portion is recessed from an outer plane of the first wall. The cavity is to receive the tray therein. The tray has an edge portion, the edge portion being received in the recessed portion and forming a gap between the outer plane of the first wall and the edge portion.

Abstract: An example system includes a stacking portion having a leading edge portion and a trailing edge portion, the stacking portion being to receive print media transported into the stacking portion in a direction from the trailing edge portion to the leading edge portion; a bar clamp extending longitudinally in the direction of transport of the print media; and a driver arrangement to selectively extend the bar clamp onto the stacking portion and to retract the bar clamp away from the stacking portion.
