Proof printing using recycled marking material

A method comprising:

• supplying used marking material to a marking material supply container within a printing device, said used marking material being previously used in a previous printing process and previously removed from one or more photoreceptors;
• feeding said used marking material from said material supply container to a photoreceptor within said printing device;
• transferring said used marking material to a sheet of media in a printing process performed by said printing device that produces proof prints, said proof prints comprising printed sheets used to verify at least one of content and layout of printed material, said proof prints not being required to comply with a print quality or print durability standard;
• and
• fusing, using a heating element within said printing device, said used marking material to said sheet of media at a temperature that is insufficient to comply with said print quality or print durability standard.

A proof printing device comprising:

• a marking material supply container containing used marking material, said used marking material being previously used in a previous printing process and previously removed from one or more photoreceptors;
• a photoreceptor adjacent said marking material supply container, said marking material supply container feeding said used marking material to said photoreceptor;
• and
• a sheet transport device adjacent said photoreceptor, said sheet transport device feeding a sheet of media to said photoreceptor, said photoreceptor transferring said used marking material to said sheet of media in a printing process performed by said printing device that produces proof prints, said proof prints comprising printed sheets used to verify at least one of content and layout of printed material, said proof prints not being required to comply with a print quality or print durability standard.

A proof printing device comprising:

• a marking material supply container containing used marking material, said used marking material being previously used in a previous printing process and previously removed from one or more photoreceptors;
• a photoreceptor adjacent said marking material supply container, said marking material supply container feeding said used marking material to said photoreceptor;
• a sheet transport device adjacent said photoreceptor, said sheet transport device feeding a sheet of media to said photoreceptor, said photoreceptor transferring said used marking material to said sheet of media in a printing process performed by said printing device that produces proof prints, said proof prints comprising printed sheets used to verify at least one of content and layout of printed material, said proof prints not being required to comply with a print quality or print durability standard, and
• a heating element adjacent said photoreceptor, said heating element fusing said used marking material to said sheet of media at a temperature that is insufficient to comply with said print quality or print durability standard.
