Abstract: Obstacle detection for a moving element activated by a motor is disclosed. The obstacle detection may comprise a controller to: move the element at a substantially constant speed; determine an actual torque value to move the element at the constant speed; determine a torque parameter based on the actual torque value; comparing the torque parameter with a threshold value; and determining the presence of an obstacle if the torque parameter is above the torque parameter threshold; wherein the torque parameter is determined based on a set of historical torque values and the actual torque value.

Abstract: In one example, a device for unwinding or winding multiple rolls of print substrate includes multiple spindles each to hold a roll of print substrate and a differential operatively connected to one end of each spindle. The spindles are aligned with one another lengthwise along a spindle axis and the differential is to output torque along a differential axis offset from the spindle axis to turn the spindles on the first axis.

Abstract: An example apparatus to produce a three-dimensional object comprises a controller, a build area configured to receive a layer of particulate material, a printhead, and an ultraviolet light emitting diode energy source. The controller is to cause the printhead to deposit a liquid which absorbs ultraviolet radiation onto the layer of particulate material. The controller is further to cause the ultraviolet light emitting diode energy source to irradiate the liquid, after the liquid has been deposited onto the layer of particulate material, thereby to heat the liquid and cause a portion of the particulate material to solidify.

Abstract: Examples relate to methods to heat a print agent deposited on a print agent, print an image on a print media and heating systems for a heating a print agent deposited on a print media. A heating system comprises a radiation emitter to irradiate a print agent deposited on a print media, a reflector to reflect a radiation emitted by the radiation emitter back to the radiation emitter, and a displacing member to shift the heating system between a pre-heating position wherein the radiation reflected back to the radiation emitter has a higher magnitude and a heating position wherein the radiation reflected back to the radiation emitter has a lower magnitude.
