Abstract

A system for automatically filling a reservoir. The system includes a first mechanism that automatically determines one or more parameters associated with the reservoir. A second mechanism fills the reservoir with an appropriate amount and type of filler based on the one or more parameters. In a specific embodiment, the one or more parameters include filler type and current filler level information. The parameters also include an identification number associated with a user of the reservoir. Upon filling of the reservoir, a billing system automatically bills or charges a user based on the identification number and filler level information obtained via the first mechanism. The billing system includes a database that maintains billing information associated with the identification number. The billing system further includes a network connection that facilitates communications with the database. A control panel and accompanying user-interface software enables a user to edit the identification number and/or to edit a charge number associated with the identification number. A reservoir sensor measures the current filler level in the reservoir and provides the filler level information in response thereto. A dispensing container accommodates the reservoir and transfers filler from the dispensing container to the reservoir in response to a signal from the first mechanism. A container level sensor senses current filler levels in the container and provides container filler level information to a remote monitoring system via a network in response thereto. In a more specific embodiment, the reservoir is a printer cartridge, and the filler is printing consumable, such as toner. The first mechanism includes an electronic storage device attached to the printer cartridge that communicates with the reservoir sensor and maintains the parameters describing the reservoir.

Claims

1. A toner dispensing system comprising:

at least one toner reservoir;

a receptacle for receiving a removable toner cartridge;

a controller;

a user interface in communication with said controller;

a display coupled to said controller; and

a feed system adapted to transfer toner from said reservoir to said cartridge in response to said controller.

2. The invention of claim 1 wherein said receptacle includes a contact adapted to engage a contact on said cartridge.

3. The invention of claim 2 wherein said contact is an E-LABEL type contact and said system includes an E-LABEL reader/writer.

4. The invention of claim 3 wherein said controller is adapted to fill said cartridge in respond to data stored on said E-LABEL type contact.

5. The invention of claim 3 wherein said controller is adapted to fill said cartridge in response to data entered by a user via said user interface.

6. The invention of claim 3 wherein said controller is adapted to obtain printer cartridge information from a printer database.

7. The invention of claim 1 further including a card reader.

8. The invention of claim 1 further including a network interface.

9. The invention of claim 8 wherein said controller includes means for accessing a charging system.

10. The invention of claim 8 wherein said controller includes means for accessing a billing system.

11. The invention of claim 8 wherein said controller includes means for accessing an accounting system.

12. A method for refilling a cartridge including the steps of:

inserting said cartridge into a receptacle of a dispensing system, said dispensing system having;

at least one reservoir;

said receptacle for receiving said removable cartridge;

a controller;

a user interface in communication with said controller;

a display coupled to said controller; and

a feed system adapted to transfer material from said reservoir to said cartridge in response to said controller;

using said user interface to initiate a refill operation; and

removing said cartridge from said receptacle.

13. The invention of claim 12 further including the step of automatically detecting a refill amount for said cartridge.

14. The invention of claim 12 further including the step of automatically billing a user for said refill operation.

15. The invention of claim 12 further including the step of automatically detecting a correct type of toner and dispensing the correct type of toner.
