摘要： A liquid discharge device (1A, 1) includes a media reel-out unit (3) for reeling media (M) out, a reel-out volume adjustment unit (37) for adjusting the reel-out volume of the media (M) from the media reel-out unit (3) based on change in the slack volume (W) of the media (M) at a position downstream from the media reel-out unit (3), a first sensor (13) arranged at a position facing at least one edge part (11A) in the media width direction, and a second sensor (15) spaced apart from the first sensor (13) in the media width direction. Both the media slack volume (W) and the presence or absence of meandering of the media (M) can be ascertained using sensing information of the first sensor (13) and the second sensor (15).

摘要： A method evaluates printhead position in a staggered full width array (SFWA) printhead assembly (230). The method includes selecting a first printhead configuration (232,234,236,238) for printing a first test pattern on an image receiving member, generating positional correction data for roll and stitch displacements obtained from captured image data of the first test pattern, comparing the positional correction data to at least one threshold in a displacement range, and operating at least one printhead actuator (220) in accordance with the positional correction data in response to the positional correction data exceeding at least one predetermined threshold in the displacement range.

摘要： A method including printing a calibration pattern with a wide array printhead having a plurality of printhead dies. The method includes scanning the calibration pattern with a scanbar having a width less than a width of the wide array printhead by indexing the scanbar to a plurality of selected positions across a width of the calibration pattern and providing a scanned calibration image at each selected position, the calibration images together providing a scan of the full width of the calibration pattern, and measuring alignment between successive printhead dies based on the calibration images.

摘要： An image forming apparatus (100) includes a human sensor (10), an image forming section (20), an internal sensor (30), a power supply section (40), a controller (50), and a communication section (60). The internal sensor (30) includes a first internal sensor (31) and a second internal sensor (32). The first internal sensor (31) detects a quantity that varies by operation of the image forming section (20). The second internal sensor (32) detects a state of operation of the image forming section (20). In a power saving state, the controller (50) controls, based on a result detected by the human sensor (10), the power supply section (40) to supply electric power to the first internal sensor (31) and not to supply electric power to the second internal sensor (32).
