Abstract: Certain examples described herein relate to calibrating a cleaning element for a printhead. A print medium sensor is aligned with a nozzle plane of the printhead to detect displacement, during a print job, of a print medium out of the nozzle plane. Relative movement between the cleaning element and the printhead is enacted. During this movement, activation of the print medium sensor is detected. A reference position for the cleaning element is stored based on the detected activation.

Abstract: Disclosed herein is a print head maintenance cartridge, a printing device and a method of controlling a wiping subsystem of a print head maintenance cartridge. The print head maintenance cartridge comprises a wiping subsystem with a wiping material to wipe a print head; a clean material roll, wherein a clean part of the wiping material is rolled up on the clean material roll at least in part; a brake to generate a first brake force applied to the wiping material; and a friction element to generate a second brake force applied to the wiping material, wherein the friction element compensates at least in part a change in the first brake force to control a total brake force, wherein the total brake force is the sum of the first and second brake forces.

Abstract: The present disclosure relates to vinyl substrate printing. In an example, a vinyl printing apparatus is disclosed wherein the apparatus comprises a media path to convey a vinyl substrate along a feed direction from a substrate supply to a print zone; an inkjet printhead to print on the print substrate at the print zone; and a heater upstream of the print zone to heat the print substrate to evaporate a plasticizer from a surface of the print substrate.

Abstract: Disclosed herein is a spittoon cartridge for a printing device, a printing device and a method of controlling a spittoon cartridge. The spittoon cartridge comprises a waste tank to store material ejected from a print head; a transfer unit to transfer material ejected from the print head into the waste tank; and a floater movably arranged in the spittoon cartridge, wherein a position of the floater depends on a filling level of the waste tank and wherein the floater impedes transfer of material by the transfer unit if the floater reaches a predefined warning position.
