Abstract: Aspects of the present disclosure relate to a printing system. In one example, the printing system comprises a print substrate supply mechanism and a conveyor belt. The print substrate supply mechanism is to supply print substrate to the conveyor belt and the conveyor belt is to advance the supplied print substrate. During a substrate loading operation of the printing system, the print substrate supply mechanism prevents motion of the substrate such that when the conveyor belt is activated the supplied substrate slides over the conveyor belt.

Abstract: A printing system is described, which comprises: a conveyor belt; a first substrate supply mechanism to supply a cleaning substrate to said conveyor belt; wherein said conveyor belt is to advance a supplied cleaning substrate, and said first substrate supply mechanism is controllable to adjust motion of said substrate relative to said conveyor belt such that when said conveyor belt is activated said supplied cleaning substrate slides relative to the conveyor belt; and said printing system further comprising a friction adjustment mechanism to adjust an amount of friction between said conveyor belt and said supplied substrate.

Abstract: An example apparatus is disclosed for transporting a substrate through a printing device. The apparatus comprises a shaft to carry the substrate, a motor to rotatably drive the shaft, a motor driver to provide a control signal to the motor to drive the shaft, a transport arrangement to draw the substrate from the shaft, and a controller to cause the motor driver to drive the shaft at a predetermined rotational speed, to cause the transport arrangement to apply tension to the substrate, and to detect a winding direction of the substrate on the shaft based on the control signal.
