Abstract
An implementation of a printer ink delivery system and method for increasing the efficiency of space utilization within a printer includes at least one available-space-conforming internal ink tank adapted to fit within difficult to access areas within a printer's enclosure. A fill port allows the temporary attachment of an externally located, ergonomically shaped ink refill canister. By utilizing space which otherwise might go unused for placement of the internal ink tank, a smaller printer enclosure may be designed. By providing a fill port adapted for attachment of ergonomic ink refill canister, the user is easily able to refill the internal ink tank.
Claims19
An ink delivery system for a printer, comprising:
- an internal ink tank, carried within a printer enclosure, the internal ink tank comprising at least one lobe extending into and occupying an otherwise unused region within the printer enclosure;
- and
- a fill port, in communication with the internal ink tank.
An ink storage system for a printer, comprising:
- an internal ink tank carried within a printer enclosure comprising first and second lobes, each lobe extending into and occupying an otherwise unused region within the printer enclosure, wherein the first and second lobes are connected by an isthmus;
- a first fill port, in communication with the internal ink tank;
- an ink refill canister, adapted for attachment to the first fill port;
- a plurality of internal color ink tanks associated with color ink carried within the printer enclosure having at least one lobe extending into and occupying an otherwise unused region within the printer enclosure;
- a second fill port, in communication with the internal color ink tanks;
- and
- an ink refill canister, adapted for attachment to the second fill port.
A method of designing an ink delivery system for a printer, comprising:
- determining a size and shape of a printer enclosure;
- and
- designing an internal ink tank within the printer enclosure, wherein the internal ink tank comprises first and second lobes connected by an isthmus, wherein the first and second lobes are located to reduce an overall size of the printer enclosure.
A method of supplying ink, comprising:
- attaching an ink refill canister to a fill port of a printer;
- transferring ink from the ink refill canister into an internal ink tank, wherein the ink fills portions of the internal ink tank comprising at least two lobes connected by an isthmus;
- and
- removing the ink refill canister.
