US Classification:

347 6, 347 19

Abstract:

A method is disclosed.

Abstract:

A method is disclosed. The method includes monitoring a sensor for measured vacuum pressure within a print head, determining if the vacuum pressure measured at the sensor is less than a predetermined pressure threshold and indicating that the print head is ready to be decoupled from the maintenance station if the measured vacuum pressure is less than the predetermined pressure threshold.

US Classification:

169 46, 169 60

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.

US Classification:

347 16

Abstract:

Systems and methods for a dryer unit of a printer. In one embodiment, a dryer unit includes a light source having a plurality of lamps. The dryer unit further includes a controller that associates a target output power with each of the lamps of the light source. When in operation, the controller determines a speed of a printable medium that passes through the dryer unit. The controller is able to vary an intensity of light generated by the light source based on the speed of the printable medium by varying which of the lamps of the light source are energized to their target output power.

US Classification:

347 16

Abstract:

Embodiments described herein provide variable heat control for a printer. One system includes a dryer operable to dry ink applied to a print medium. The system also includes a controller communicatively coupled to the dryer and operable to filter a bitmap to provide variable heat control from the dryer to the applied ink according to the bitmap to attach the ink to the print medium. The print medium may be a continuous form print medium. In this regard, the controller maybe operable to determine a speed at which the continuous form print medium is moving, to generate a heat control signal operable to provide the variable heat control, and to delay transmission of the heat control signal based on the determined speed of the continuous form print medium until the ink applied to the continuous form print medium is within range of the dryer.

Abstract:

Structures for radiant dryer units of a printer. A radiant dryer unit includes a reflector element that reflects light waves from a light source back towards a printable medium to dry ink printed on the medium. The reflector element includes a plurality of modular sections. Each modular section includes a base portion having a reflective surface, and includes legs that protrude from an opposing surface of the base portion. The modular sections are affixed to one another so that the reflective surfaces of the modular sections form an aggregate reflective surface that faces toward the light source of the radiant dryer unit.
