A printing apparatus provided with a transportation mechanism for a printing medium includes: a storage configured to store a machine-learned model that outputs a setting value of the transportation mechanism for causing, based on state variables including a print length as a length of a print product printed on the printing medium, the print length to be close to a reference; and a processor configured to perform printing by controlling the transportation mechanism in accordance with the setting value acquired based on the machine-learned model.

A printing apparatus includes a feeder that feeds a medium in a feeding direction, a head including a row of nozzles arranged side by side in the feeding direction and movable in a scanning direction, an irradiator that radiates light onto a region longer in the feeding direction than the nozzle row and that is movable in the scanning direction together with the head, and a controller that alternatingly causes the head to move in the scanning direction and concurrently the nozzles to discharge ink while causing the irradiator to radiate the light, and the feeder to feed the medium in the feeding direction. The controller is capable of dividing the nozzle row into an upstream-side nozzle row and a downstream-side nozzle row located on a downstream side in the feeding direction from the upstream-side nozzle row, and individually controlling discharge of ink from the nozzles of each of the upstream-side nozzle row and the downstream-side nozzle row. The controller is capable of dividing the irradiator into an upstream-side irradiator, an intermediate irradiator adjacent to the upstream-side irradiator on a downstream side in the feeding direction, and a printless region irradiator adjacent to the intermediate irradiator on a downstream side in the feeding direction, and individually controlling lighting and extinguishing of each of the irradiators defined by the division.

In an example of the disclosure, power of a first light beam emitted across a web media along a length of the roller is measured utilizing a first optical transmitter and first optical receiver pair situated adjacent to a roller. Power of a second light beam emitted across a length of the roller is measured utilizing a second optical transmitter and second optical receiver pair situated adjacent to the roller. A media height non-uniformity is identified based upon of the measurement of the power of the first light beam and the measurement of the power of the second light beam.

A dual nip release mechanism includes: a rigid actuator body including a tail portion with a handle and a pivotally-mounted head portion having a nose member extending therefrom; a rocker arm pivotally mounted about a rocker arm shaft, the rocker arm having a proximal end for engagement with part of the nose member and a distal end engaged with a first shaft; and legs hingedly connected to the tail portion, each leg having a foot engaged with a second shaft and a heel for camming engagement with a fixed plate. During use, actuation of the handle causes simultaneous movement of the first and second shafts from a nip closed position to a nip open position via pivoting of the rocker arm and simultaneous camming engagement of the heel with the fixed plate.
