Abstract: Methods and systems supply used marking material to a printing device marking material supply container. The used marking material was previously used in a printing process and was previously removed from one or more photoreceptors. The methods/systems feed the used marking material from the material supply container to a photoreceptor within the printing device and transfer the used marking material to a sheet of media in a printing process performed by the printing device that produces “proof prints.” These proof prints are printed sheets that are used to verify content and/or layout of printed material. The proof prints are not required to comply with any print quality or print durability standard. The methods/systems also fuse (using a heating element within the printing device) the used marking material to the sheet of media at a reduced temperature that is insufficient to comply with any print quality or print durability standard.
