Abstract: A printing apparatus is disclosed herein. The apparatus comprises a platform defining a printing zone to hold a media moveable along a media path direction; a first sensor at a first location along the media path direction to measure a media advance at the first location; a second sensor located at a second location along the media path direction downstream the first location, the second sensor to measure the media advance at the second location; and a controller. The controller to determine a deformation gradient of the media based on a first set of measurements of the media advance by the sensors at the first and second locations and adjust an image to be printed based on the deformation gradient.

Abstract: An apparatus is disclosed herein. The apparatus comprises a carriage to move laterally in a scanning direction over a platen, a scan beam to support the carriage over the platen, a mechanism to move the scan beam vertically, and a media holder. The media holder comprises a central portion to hold a media on the platen, a first end couplable to the platen at a coupling position, and a second end couplable to the scan beam such that the second end moves vertically along with the scan beam.

Abstract: Examples relate to a drying cylinder for an image forming apparatus. The drying cylinder comprises a curved wall and a plurality of gas outlets spaced apart over the curved wall. The drying cylinder is to continuously rotate about its longitudinal axis and provide gas through the plurality of gas outlets perpendicularly onto a print medium with printing fluid deposited thereon to dry the printing fluid.

Abstract: A print substrate transport system comprises a print substrate supply mechanism and a tensioner. The print substrate supply mechanism is configured to advance print substrate to a printing zone in a discontinuous motion. The tensioner is provided downstream of the print printing zone and is configured to guide a path of the print substrate from the printing zone to a post-processing zone, to control tension in the print substrate in the post-processing zone, and to convert the discontinuous motion of the substrate to continuous motion. A print substrate transport method comprises supplying a print substrate to a printing zone in a discontinuous motion, controlling a tension of the print substrate on a path downstream of the printing zone and converting the motion of the substrate from the discontinuous motion to a continuous motion.

Abstract: A system is disclosed. The system comprises a roller with a spindle to wind and/or unwind a roll of media, a media advancement sensor to measure the advancement of the media, and a controller. The controller is to control the spindle to rotate an angular displacement, and to determine a calculated media advancement based on the angular displacement and a radius of the roll of media. The controller is also to receive from the media advancement sensor a measured media advancement. The controller is further to detect that a displacement difference between the measured media advancement and the determined media advancement exceeds a predetermined threshold. If the displacement difference exceeds the predetermined threshold a slippage condition is detected.

Abstract: A mark mitigating device for a printing device has a protector sheet to cover ribs of a printer platen of the printer device to prevent the ribs from causing marks on print media. The mark mitigating device further has a fixing system to fixate the mark mitigating device relative to the printer platen. The protector sheet has an opening to pass through vacuum applied by the printer platen to attract print media.

Abstract: An apparatus (100) for a large format printer (400) to support a spindle (102) of a roll of media comprises at least one supporting member (104, 104a, 104b, 104c) to support the weight of the spindle (102) when the spindle is loaded into the apparatus (100). The apparatus also comprises a cradle (108) to support the spindle (102) as it is loaded onto or unloaded from the at least one supporting member (104). The cradle (108) is moveable between a first position to receive the spindle (102) and a second position when the spindle is supported by the at least one supporting member (104). The apparatus also comprises a shock absorbing member (110) in contact with the cradle (108). The cradle moves between the first and second positions as the spindle (102) is loaded into the apparatus (100) and the shock absorbing member (110) absorbs kinetic energy of the cradle (108) as it moves from the first position to the second position.

Abstract: A platen protector for a printer device has a protector blanket to cover a printer platen of the printer device to prevent from causing scratches on print media by the printer platen. The platen protector has a fixing system to fixate the platen protector relative to the printer platen. The protector blanket is porous to pass through vacuum applied by the printer platen to attract print media.
