Abstract
An electronic device includes a carriage to move along an axis relative to a platform. In addition, the electronic device includes a print head disposed within the carriage to move with the carriage and to deliver a print agent to the platform. Further, the electronic device includes a cooling system. The cooling system includes an air source to deliver air to the print head within the carriage to cool the print head. The cooling system also includes a pressure sensor to measure a pressure of a first zone within the carriage. Moreover, the cooling system includes a controller to control a flow rate of the air into the first zone or from the first zone in response to the measured pressure to maintain the first zone at a positive pressure with respect to a second zone outside the carriage.
