Abstract
An example method comprises identifying, by a processor, a gap in a housing of a printing apparatus and positioning an inlet of a conduit inside the housing proximate the gap. The inlet is fluidly connected to a fan, and the fan is powered to create a pressure differential across the housing to minimize the amount of air inside the housing being able to escape the housing via the gap.
Claims15
A method comprising:
- identifying, by a processor, a gap in a housing of a printing apparatus;
- positioning, an inlet of a conduit inside the housing;
- fluidly connecting the inlet to a fan;
- powering the fan to create a pressure differential across the housing to minimize the amount of air inside the housing being able to escape the housing via the gap.
A printing apparatus comprising:
- a casing for a printing element of the printing apparatus, the casing comprising a gap through which air may pass from the inside to the outside of the printing apparatus;
- a pressure source to create a suction pressure;
- a conduit fluidly connected to the pressure source and positioned so as to create a pressure differential across the casing to minimize the amount of air inside the casing being able to escape the casing via the gap.
A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processor of a printing system cause the processor to:
- locate an opening in an exterior casing of a printing system via which air from inside the printing system may escape;
- and to
- create a pressure state within the printing system proximate the opening such that air from outside the printing system is drawn inside the printing system via the opening.
