Abstract
Examples described herein include devices and methods for adjusting a suction force for a media holddown, comprising detecting an advancement of a media (114) relative to a media holddown surface along a media advancement direction (X), wherein the holddown surface has a plurality of suction zones arranged along the media advancement direction, and adjusting a suction force in the respective suction zones in accordance with the advancement of the media relative to the media holddown surface.
Claims15
A method for adjusting a suction force for a media holddown, comprising:
- detecting an advancement of a media relative to a media holddown surface along a media advancement direction, wherein said holddown surface has a plurality of suction zones arranged along said media advancement direction;
- and
- adjusting a suction force in said respective suction zones in accordance with said advancement of said media relative to said media holddown surface.
An apparatus for adjusting a suction force for a media holddown, comprising:
- a transport unit to advance a media along a media advancement direction, wherein said transport unit comprises a media holddown surface with a plurality of suction zones arranged along said media advancement direction;
- and
- at least one vacuum source in fluid communication with at least one of said plurality of suction zones to adjust a suction force in said suction zones in accordance with said advancement of said media relative to said media holddown surface.
A computer-readable medium comprising computer-readable instructions, such that said instructions, when read on said computer, implement a method comprising:
- detecting an advancement of a media relative to a media holddown surface along a media advancement direction, wherein said holddown surface has a plurality of suction zones arranged along said media advancement direction;
- and
- adjusting a level of a suction force in said respective suction zones in accordance with said advancement of said media relative to said media holddown surface, in particular activating or deactivating said suction force in at least one of said suction zones in accordance with said advancement of said media relative to said media holddown surface.
