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.

Abstract: An apparatus and method for refilling pigment cartridges. The apparatus includes a device for engaging a pigment cartridge and a pigment reservoir. A pigment transfer device, having an enabling input, is coupled to convey pigment from the pigment reservoir to the device for engaging a pigment cartridge upon activation of the enabling input. The apparatus also includes an accounting device coupled to the enabling input, such that the accounting device activates the enabling input upon receiving an account stimulus, and, thereby effects a transfer of pigment from the pigment reservoir to the pigment cartridge. In illustrative embodiments the pigment is toner or ink for laser printers and inkjet printer respectively. The accounting stimulus may be approval for a credit card transaction, a cost accounting systems, or may be cash payment.
