Abstract
An apparatus for developing a latent image recorded on an imaging surface with a custom color toner, including a developer housing for developing a portion of the latent image with the toner of custom color. The developer housing includes a donor member for transporting toner of the custom color to a development zone to develop the latent image. A replaceable reservoir unit is provided for mixing and supplying the custom color toner to the donor member. An array of toner dispensers is provided for supplying various primary color toners, as required, to achieve the custom color, and additional reservoirs having various colored toners therein to allow for faster convergence to a given point in the color space.
Claims10
An apparatus for developing a latent image recorded on an imaging surface with a custom color toner, comprising:
- a developer housing including a donor member for transporting toner of said custom color on an outer surface of said donor member to a development zone;
- a first reservoir for storing a supply of toner of said custom color;
- a dispenser for dispensing toner of a first color and toner of a second color into said first reservoir to form said custom color,
- a color controller, in communication with said dispenser, for determining appropriate amounts of toner of said second color to be added to said first reservoir to achieve the custom color;
- a second reservoir for storing a supply of toner, said second reservoir being interchangeable with said first reservoir.
A housing for producing toner having a custom color, comprising:
- a replaceable first reservoir for storing a supply of developer material comprising toner of a first color;
- other replaceable reservoirs for storing a supply of developer material comprising toner of other colors, said other replaceable reservoirs being interchangeable with said first reservoir in a housing;
- an array of dispensers for dispensing toner of other colors into said housing, said reservoirs including means for mixing toner of said first color and toner of said other colors together to form toner of said custom color;
- and a color controller, in communication with said dispensers, for determining appropriate amounts of toners of said other colors to be added to said reservoirs to achieve the custom color.
A method of forming toner images having a custom color in a printing system having a development housing with a plurality of interchangeable reservoirs with each having toner of a different color, said method including the steps of:
- selecting a custom color;
- associating the selected custom color to a color space found in one of the plurality of interchangeable reservoirs;
- and
- inserting the associated one of the plurality of interchangeable reservoirs into the printing system.
