Abstract
A printing apparatus that prints images onto sheets includes a conditioner that scents selected images of a job. For example, the job can be a magazine that advertises a particular fragrance or fragrances. A fragrance or scent is placed in a reservoir which is transferred via a hydrophilic donor-like roll and deposited onto a sheet by way of a nip that is engaged only when scenting is required.
Claims7
A device for adding scented moisture to a copy sheet, comprising:
- a reservoir;
- a quantity of scented liquid stored in said reservoir;
- a pair of cylindrical rolls, each having an outer cylindrical surface, said rolls being aligned with respect to one another along their axes so as to define a nip between said outer cylindrical surfaces;
- a metering roll including a circumferential surface in contact with one of said rolls for controlling the flow of scented liquid from said reservoir to at least one of said rolls;
- and
- a controller for selectively deactuating one of said pair of cylindrical rolls when scenting of a copy sheet is not required.
A sheet scenting system, comprising:
- at least one pair of cylindrical rolls, said rolls being aligned with respect to one another along their axes so as to define a closely spaced nip between outer surfaces thereof;
- at least one metering roll having a circumferential surface in contact with one of said rolls for forming a nip therewith and controlling the amount of fluid supplied to said one of said rolls;
- a reservoir;
- a quantity of scented liquid stored in said reservoir;
- a pump for supplying said scented liquid from said reservoir to the nip formed between said at least one metering roll and said one of said rolls;
- and
- a controller for selectively controlling rotation of one of said at least one pair of cylindrical rolls depending on whether scenting of the sheet is required.
A printing apparatus that places page image information onto copy sheets includes an apparatus for adding scented moisture to the copy sheets before they exit the printing apparatus, comprising:
- a reservoir;
- a quantity of scented liquid stored within said reservoir;
- a pair of cylindrical rolls, each having an outer cylindrical surface, said rolls being aligned with respect to one another along their axes so as to define a closely spaced nip between said outer cylindrical surfaces;
- a metering roll including a circumferential surface in contact with one of said rolls for controlling the flow of liquid from said reservoir to said one of said rolls;
- and
- a controller for stopping one of said pair of cylindrical rolls from rotating in order to prevent scenting of the copy sheets.
