Abstract
Disclosed herein is a print head maintenance assembly, a printing device and a method of controlling a print head maintenance assembly in a printing device. The print head maintenance assembly comprises a maintenance cartridge comprising a positioning flag, wherein the maintenance cartridge is movable along a maintenance path in a direction of movement; and a sensor to detect the positioning flag to determine the position of the maintenance cartridge along the maintenance path.
Claims19
A print head maintenance assembly, the print head maintenance assembly comprising:
- a maintenance cartridge comprising a positioning flag, wherein the maintenance cartridge and the positioning flag are movable along a maintenance path as the maintenance cartridge cleans a print head of a printing device;
- and
- a sensor to detect the positioning flag and generate a sensor signal indicating a distance between the sensor and the positioning flag,
- wherein a controller of the printing device receives the sensor signal from the sensor and determines a position of the maintenance cartridge along the maintenance path relative to an axis of the printing device based on the sensor signal.
A printing device comprising:
- a print head, wherein the print head is movable along a print head path in a scanning direction;
- a maintenance cartridge comprising a positioning flag, wherein the maintenance cartridge and the positioning flag are movable along a maintenance path to clean the print head;
- a sensor to detect the positioning flag and generate a sensor signal indicating a distance between the sensor and the positioning flag;
- an actuator to move the maintenance cartridge along the maintenance path;
- and
- a controller to control the actuator to move the maintenance cartridge, receive the sensor signal from the sensor, and determine a position of the maintenance cartridge along the maintenance path relative to an axis of the printing device based on the sensor signal.
A method of controlling a print head maintenance assembly in a printing device, the print head maintenance assembly comprising:
- a maintenance cartridge having a positioning flag, wherein the maintenance cartridge and the positioning flag are movable along a maintenance path to clean a print head of the printing device;
- and
- a sensor to detect the positioning flag;
- the method comprising:
- moving the maintenance cartridge along the maintenance path until the sensor is triggered by the positioning flag;
- receiving, by a controller, a sensor signal from the sensor indicating a distance between the sensor and the positioning flag;
- and
- determining, by the controller, a position of the maintenance cartridge along the maintenance path relative to an axis of the printing device based on the sensor signal.
