Abstract: Apparatus is described that comprises a printer carriage (100), comprising a printhead (105), at least one sensor (101, 102) for scanning an image deposited on a print media by the printhead (105) and a spectrophotometer (104) connected to the at least one sensor (101, 102) for generating data based on a reference image (120) on a test print media (110). The sensor (101, 102) is calibrated based on the generated data to detect a specific ICC profile, and wherein, in use, the sensor (101, 102) scans and digitizes an image of a final print media as the image is being printed on the final print media; and wherein the sensor (101, 102) is connected to a controller (106) that performs image quality analysis of the digitized image to determine whether colour deviation has occurred.

Abstract: A printing carriage comprises a printhead, and two sensors for scanning an image deposited on a print media by the printhead. The sensors are provided on opposite sides of the printhead in a direction of movement of the printhead so that, during a printing pass of the printhead on the print media, one sensor is positioned on a trailing side of the moving printhead.

Abstract: An example scanner assembly includes a housing formed with corners to allow an image sensor line to align cornerwise. An example scanner apparatus may include a plurality of scanner assemblies with an image sensor line oblique to the media advance direction.

Abstract: An image digitizing apparatus has an image digitizing sensor to read an image from media passing the image digitizing sensor, and a transport to move the media past the image digitizing sensor. The transport includes a first driven transport element, and a second driven transport element biased towards the first driven transport element. The first driven transport element and the second driven transport element receive the media therebetween.

Abstract: Examples of a method for detecting misalignment cause a printer to print a calibration pattern on a recording medium sheet. The calibration pattern includes graduated measurement scales positioned so that: when the calibration pattern is printed without misalignment on a recording medium sheet of predetermined dimensions, matching graduations of plural measurement scales in the calibration pattern are printed at respective reference locations on the recording medium sheet that correspond to corners of the recording medium sheet (or to spaced positions along a line where folding of the recording medium sheet by a folding apparatus is intended to take place). When the calibration pattern is printed with misalignment on a recording medium sheet of predetermined dimensions, non-matching graduations of the plural measurement scales are printed at the reference locations on the recording medium sheet.

Abstract: In some examples, a media stacker includes a drawer defining a chamber, and a plurality of moving elements to engage media sheets of different sizes as the media sheets are output from a system. The plurality of moving elements are to slide the media sheets to a target position in the drawer, and the plurality of moving elements are to disengage from the media sheets once the media sheets have reached the target position. A plurality of retaining elements are to engage the media sheets of the different sizes as the media sheets slide into the drawer.

Abstract: A printing system includes a print bar, a plurality of printheads installed on the print bar and an auxiliary printhead moveable parallel to the print bar. A number of first nozzles of the auxiliary printhead substitute for a number of second nozzles of the printheads during a nozzle servicing operation performed on the second nozzles.

Abstract: A sensor can sense a weight of items in an area. A sensor can sense a height of items in the area. An available capacity of the area can be determined based on the sensed weight and height.
