The invention comprises a method for forming a 3D object, wherein the method comprises the step of depositing a support structure. According to the invention, the support structure comprises an organic di-acid having a molecular weight of 300 g/mole or less. The invention further relates to an assembly of a 3D printed object and a support structure.

Method for printing 3D structures

In a method for determining a maintenance performance of a maintenance unit of an inkjet printing system, the inkjet system comprises an inkjet print head having an orifice surface, the orifice surface comprising an orifice, which orifice is in fluid communication with an ink chamber. The method comprises operating the maintenance unit to perform a maintenance operation on the orifice surface of the inkjet print head and detecting the presence of a wiper element or amount of ink over the orifice by detecting a pressure wave in the ink chamber and analyzing the detected pressure wave to determine the maintenance performance of the maintenance unit.

Method for determining maintenance unit performance

A method of making an endless image-forming medium starting from a strip of semi-crystalline support material, which strip extends between a first and second end, wherein the ends of the strip are brought together and fused to form an endless support, and the fused ends are post-crystallized, wherein prior to the application of the image-forming layer to the support at least a portion of the support is stretched, and the stretched part of the support is heated to a temperature above the glass transition temperature of the support material.

Method of making an endless image-forming medium

A device and method associated therewith for transferring a toner image from an image-forming medium to a receiving material comprising: an image-forming medium, an endless movable intermediate medium provided with a top layer in contact with the image-forming medium in a first transfer zone, a heater for heating the toner image on the top layer of the intermediate medium, a biased belt which in a second transfer zone can be brought into contact with the intermediate medium, a transport device for transporting the receiving material through the second transfer zone, and a material for removing from the top layer of the intermediate medium impurities transferred thereto, by contacting the impurities with a material metal compound which breaks down the impurities.

Intermediate transfer member having a material which breaks down

An imaging apparatus including a transferring device for transferring a toner image from an image-forming medium to a receiving material, comprising an endless movable intermediate provided with a top layer which in a first transfer zone is in contact with the image-forming medium, heater for heating the toner image on the top layer of the intermediate, a pressure applying roller which in a second transfer zone can be brought into contact with the intermediate, a transport roller for transporting the receiving material through the second transfer zone, wherein removal of impurities transferred by receiving materials to the top layer of the intermediate is realized by absorption of the impurities by an impurity-absorbent material within the intermediate.
