摘要： Methods and apparatus for assessing power usage of at least one printer component in a printer are described. For example, based on a print instruction (the print instruction being to cause the printer to carry out a printing task), power usage requirements of the at least one printer component in carrying out the print instruction may be determined. The power usage may be determined for each of a plurality of time intervals. In some examples, the effect of the printer component(s) in carrying out the print instruction on at least one power quality measure associated with a power supply network which may be connected to the printer may be considered.

摘要： A system and method for testing printheads is disclosed. The system comprises an optical sensor mounted on a movable carriage. The optical sensor is moved past a nozzle to be tested on the printhead while the nozzle ejects ink. The output signal of the optical sensor can be used to determine when the trajectory of the ejected ink is improper.

摘要： A method of operating a printing system includes identifying groups of nozzles of a plurality of nozzles of a printhead device. The method also includes ejecting fluid drops by the printhead device from nozzles thereof and along corresponding firing paths. The method also includes controlling movement of a detector carriage including a plurality of drop detectors of a drop detector array with respect to the printhead device by a control module to align each one of the drop detectors with the respective firing paths corresponding to the respective nozzles at a predetermined time. The method also includes sensing the firing paths corresponding to the nozzles to detect a presence of the fluid drops by the drop detectors such that each one of the drop detectors senses at a same time a respective firing path corresponding to a respective nozzle for a plurality of groups of nozzles.
