Abstract
Fire control and containment for a production printing system that includes a dryer unit, an air intake fan, and an exhaust fan. A fire control and containment system includes an enclosure surrounding the dryer unit. The enclosure includes controllable doors, a temperature sensor, and an air pressure sensor in the enclosure. The fire containment and control system also includes a controller operable to detect a fire event based on changes in air pressure and air temperature in the enclosure detected by the air pressure and air temperature sensors. In response to detecting the fire event, the controller closes the doors of the enclosure to prevent the print medium from entering, controls the air intake fan and the exhaust fan to reduce the air pressure in the enclosure, and controls the dryer unit to reduce temperature in the enclosure to suppress fire.
