Abstract
A printing apparatus has a transfer member to receive an image and transfer the image to a substrate, and an airflow management unit disposed adjacent to the transfer member to define a channel between the transfer member and the airflow management unit. The airflow management unit has an injection mechanism to inject airflow into the channel, a suction mechanism to remove the airflow from the channel, and a vortex generator to generate a vortex within the channel.

A printing apparatus comprising:
- a transfer member to receive an image and transfer the image to a substrate;
- and
- an airflow management unit disposed adjacent to the transfer member to define a channel between the transfer member and the airflow management unit;
- wherein the airflow management unit comprises an injection mechanism to inject airflow into the channel, a suction mechanism to remove the airflow from the channel, and a vortex generator to generate a vortex within the channel.

A method comprising:
- providing a transfer member to receive an image and transfer the image to a substrate;
- providing an airflow management unit disposed adjacent to the transfer member to define a channel between the transfer member and the airflow management unit;
- injecting a heated airflow into the channel via an air outlet of the airflow management unit;
- removing the heated airflow from the channel via an air inlet of the airflow management unit;
- and
- providing a vortex generator to generate a vortex within the channel and inhibit the heated airflow leaving the channel upstream of the air outlet.
3 more elements
A printer comprising:
- an image forming unit to form an image using print fluid comprising pigment particles suspended in a carrier fluid;
- a blanket to receive the image from the image forming unit;
- and
- an airflow module spaced from the blanket to define an airflow channel having first and second open ends, the airflow module comprising an air outlet to pass heated airflow into the channel, an air inlet to receive output airflow from the airflow channel, and an airflow inhibitor located between the first open end and the air outlet of the airflow module, the air inlet located between the air outlet and the second open end of the channel, the airflow inhibitor to create an air seal in the region located between the first open end and the air outlet of the airflow module.
