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: In one example, a printing system is described, having a conveyor belt, a first optical sensor, a second optical sensor, and a controller. The first optical sensor is located proximate to a first edge of the conveyor belt. The second optical sensor is located proximate to a second edge of the conveyor belt, wherein the second edge is on the opposite side of the conveyor belt to the first edge. The controller receives data related to optical detection of lateral movement of the conveyor belt from the first and second optical sensors, and causes a correction for the detected lateral movement of the conveyor belt in association with a print job of the printing system.

Abstract: A tensioner device for use with a printing device is described which is to hold an end of a print target holder sheet in a substantially planar configuration across a platen of a printing device. The tensioner device can be fixed to a frame attachable to a platen of a printing device. The tensioner device has a first surface, and the frame has a second surface corresponding to the first surface. The first surface is formed to slide along the second surface in a first direction having an oblique angle with respect to a plane of the print target holder sheet. A fixing mechanism is also described which allows the first surface to be fixed to the second surface at different positions along the first direction. An apparatus including the tensioner device and the frame is also described. A system including a printer, a platen, tensioner devices and frames is also described.

Abstract: Adaptative substrate curing by ejecting a curing flow rate to a curing zone by: heating a heating fluid to a curing temperature; causing the heating fluid to flow along a plurality of serially connected chambers separated being each pair of chambers separated by a heating fluid restrictor, actuating on the heating fluid restrictor as to determine a restricted flow rate between adjacent chambers thereby defining a curing flow rate that passes from the chambers towards the curing zone.

Abstract: Examples described herein include methods and devices for systems that include a conveyor belt comprising an exterior surface and an interior surface, an embedded optical sensor disposed proximate to the interior surface of the conveyor belt to optically detect movement of the conveyor belt, and a driver to move the conveyor belt based on the detected movement of the conveyor belt.
