Abstract: In an example of the disclosure, a print job is received. The print job includes an image to be printed upon a substrate utilizing printheads. The print job is analyzed to determine a set of imaged segments, a set of image-adjacent segments, and a set of remote segments. The print job is printed upon the substrate utilizing a first set of printheads. A cooling liquid is applied to the set of image-adjacent segments of the printed print job utilizing a second set of printheads downstream from the first set of printheads. The printed job is exposed to an array of controllable illumination elements. The array of illumination elements is controlled to apply a drying illumination to the imaged segments and the image-adjacent segments of the printed print job, without providing the drying illumination to the remote segments.

Abstract: A system to carry print media through a print zone in a printer. In one example, the system includes an endless conveyor belt in a loop, a driver operatively connected to the conveyor belt under the print zone to circulate the conveyor belt through the print zone, an encoder operatively connected to the driver under the print zone to measure movement of the conveyor belt in the print zone indirectly through the driver, and a controller programmed to control the driver based on measurements from the encoder.

Abstract: In one example, a system to convey print media through a print zone in a printer includes an endless conveyor belt in a loop, a pair of drivers to circulate the conveyor belt through the print zone from opposite ends of the loop, an encoder to measure movement of the conveyor belt, and a controller programmed to control both drivers driving the conveyor belt based on measurements from the encoder.

Abstract: In an example, a media sheet conveyance system includes a first transport assembly, a plurality of subject transport assemblies, and a controller. The first transport assembly includes an endless first belt having a plurality of rows of holes, including a first and a second edge row separated by a distance “x”. Each subject transport assembly includes an endless subject belt having a subject edge row of holes, with a distance to a nearest edge row of an adjacent transport assembly being less than or equal to the distance “x.” The controller is to, in order to convey a media sheet, control a first drive roller to circulate the first belt over a first vacuum element set, and control a subject drive roller to circulate a subject belt over a subject vacuum element.

Abstract: In one example, a system to support print media through a print zone in a printer includes an endless support belt, a driver to circulate the support belt through the print zone, and an encoder unit under the print zone to measure movement of the support belt in the print zone.

Abstract: In an example a method includes, by processing circuitry, acquiring a digital image of a printed output and receiving an indication of the performance level of a printer used to print the printed output. It may be determined if the performance level meets a predetermined standard. When the performance level does not meet the predetermined standard, an indication that the predetermined standard has not been met may be generated. The digital image may be displayed for inspection.
