The present invention provides a refill adapter for coupling a closure of a toner bottle to a toner reservoir, the refill adapter comprising: a base having an insertion area for receiving the closure inserted therein and an opening mechanism for opening the closure, wherein the opening mechanism is configured to hold a first closure member of the closure and to move a second closure member of the closure relative to the first closure member along an axis between a closed position, in which the second closure member cooperates with the first closure member to close or seal an outlet opening of the closure, and an open position for dispensing toner from the toner bottle through the outlet opening into the toner reservoir; a sealing device comprising a first sealing part, which is fixed to the base, and a second sealing part, which is movable relative to the first sealing part, wherein the second sealing part is configured to be moved together with the second closure member along the axis and to thereby contact the second closure member for isolating an outer region of the closure from an inner region of the closure, which is in contact with toner. Furthermore, the invention provides a corresponding method of coupling a toner bottle to a toner reservoir, and a printing system comprising such a refill adapter and/or for performing such a method.

A toner bottle cap has a fixed member and a slide member. The fixed member is stationary relative to a toner bottle and defines a first flow passage. The slide member defines a second flow passage coaxially adjoining the first flow passage in a toner outflow direction and having a peripheral wall in sealing contact with a peripheral wall of the fixed member. The slide member is slideable relative to the fixed member in axial direction of the flow passages. One of the members has a wall part that restricts the cross-section of the flow passage of the one member and defines a toner outflow opening. The other of the members has a stop member projecting axially towards the outflow opening and closes the same when the slide member is in a closed position and opens the outflow opening when the slide member is slid in the toner outflow direction.

Disclosed is a reusable print medium having a substrate and a sacrificial layer. The sacrificial layer contains a hotmelt composition at least having an amorphous material. The amorphous material is a reaction product of a first monomer A, said first monomer A being a polyhydroxyl alcohol comprising X hydroxyl functional groups, wherein X&#x2267;2, monomer A optionally comprises a primary or secondary amine functionality; a second monomer B, being an aromatic monocarboxylic acid; a third monomer C, said third monomer C being able to form an ester linkage with an alcohol and/or an amide linkage with a primary or secondary amine; and optionally, a fourth monomer D, being an aromatic monocarboxylic acid different from the second monomer B. Also disclosed is a method of manufacturing a reusable print medium, a method of printing and recycling a print medium and an apparatus for printing and recycling a print medium.
