Abstract

A printer may include a printer housing, a service station in the printer housing, an automated carriage assembly, and a print cartridge storage compartment. The service station defines an area for servicing one or more print cartridges. The automated carriage assembly is configured to carry the particular print cartridge through a printing area during a printing operation of the printer, and to carry the particular print cartridge to the service station area for servicing. The print cartridge storage compartment is defined by the printer housing and configured to store a spare print cartridge, the print cartridge storage compartment being separate from the service station and inaccessible to the carriage assembly.

First claim

What is claimed is:

1. A printer, comprising:
a printer housing;
a service station in the printer housing, the service station defining an area for servicing one or more print cartridges;
an automated carriage assembly configured to:
carry the particular print cartridge through a printing area during a printing operation of the printer; and
carry the particular print cartridge to the service station area for servicing;

a print cartridge storage compartment defined by the printer housing and configured to store a spare print cartridge, the print cartridge storage compartment being separate from the service station and inaccessible to the carriage assembly at all times; and
a spare print cartridge identification system configured to automatically identify at least one of:
whether a spare print cartridge is present in the print cartridge storage compartment; and
identification data regarding a spare print cartridge stored in the print cartridge storage compartment.

2. A printer according to claim 1 , wherein:
the print cartridge storage compartment is configured to align the spare print cartridge in a vertical orientation; and
the print cartridge storage compartment includes a capping seal for sealing a print head of a spare print cartridge stored in the print cartridge storage compartment.

3. A printer according to claim 1 , wherein:
the print cartridge storage compartment includes a capping seal for sealing a print head of a spare print cartridge stored in the print cartridge storage compartment; and
the capping seal is biased against the print head of the spare print cartridge by a spring force.

4. A printer according to claim 3 , wherein the print cartridge storage compartment includes a protrusion for engaging the spare print cartridge, the protrusion counteracting the spring force of the capping seal against the print head.

5. A printer according to claim 1 , wherein the print cartridge storage compartment includes:
a capping seal for sealing a print head of a spare print cartridge stored in the print cartridge storage compartment; and
a removable device that supports the capping seal, the removable device being removable from the print cartridge storage compartment.

6. A printer according to claim 1 , wherein the print cartridge storage compartment is configured to clean or moisten a print head of a spare print cartridge stored in the print cartridge storage compartment.

7. A printer according to claim 1 , wherein:
the printing area is generally located at an upper part of the printer housing; and
the print cartridge storage compartment is generally located at a lower part of the printer housing.

8. A printer according to claim 1 , further comprising a spare print cartridge stored in the print cartridge storage compartment.

9. A printer according to claim 1 , wherein servicing one or more print cartridges in the service station area comprises at least one of:
storing a print cartridge; and
cleaning a print head of a print cartridge.

10. A method, comprising:
operating a printer including a printer housing, a service station located in the printer housing and defining an area for servicing one or more print cartridges, and a carriage assembly for carrying a print cartridge;
wherein during operation of the printer, the carriage assembly automatically carries a particular print cartridge through a printing area during a printing operation and to the service station for servicing;
storing a spare print cartridge in a print cartridge storage compartment at least partially defined in the printer housing and configured for storing the spare print cartridge, the print cartridge storage compartment being separate from the service station and inaccessible to the carriage assembly at all times;
automatically identifying, by a spare print cartridge identification system associated with the print cartridge storage compartment, at least one of:
whether a spare print cartridge is present in the print cartridge storage compartment; and
identification data regarding a spare print cartridge stored in the print cartridge storage compartment; and

manually transferring the spare print cartridge from the print cartridge storage compartment to the carriage assembly such that the carriage assembly may use the spare print cartridge for printing.

11. A method according to claim 10 , wherein, during storage of the spare print cartridge in the print cartridge storage compartment, a capping seal is biased against a print head of the spare print cartridge by a spring force.

12. A method according to claim 11 , wherein, during storage of the spare print cartridge in the print cartridge storage compartment, a protrusion of the print cartridge storage compartment engages the spare print cartridge to counteract spring force of the capping seal against the print head.

13. A method according to claim 10 , further comprising inserting a removable capping seal support device into the print cartridge storage compartment, the removable capping seal support device configured to support the capping seal.

14. A method according to claim 10 , further comprising the print cartridge storage compartment automatically cleaning or moistening a print head of the spare print cartridge stored in the print cartridge storage compartment.

15. A capping system for capping a print cartridge for use in a printer, the capping system comprising:
a capping seal configured to seal a print head of a spare print cartridge stored in a print cartridge storage compartment formed in a housing of a printer, the print cartridge storage compartment being inaccessible to a carriage assembly at all times; and
a biasing member configured to bias the capping seal against the print head of the spare print cartridge stored in the print cartridge storage compartment;
wherein the capping system is located in the print cartridge storage compartment and removable from the print cartridge storage compartment, the print cartridge storage compartment being separate from a service station area for servicing one or more print cartridges delivered by an automated movable print cartridge carriage assembly.

16. A print cartridge capping system according to claim 15 , wherein the biasing member comprises a spring.

17. A print cartridge capping system according to claim 15 , further comprising a protrusion configured to engage a spare print cartridge stored in the print cartridge storage compartment, the protrusion counteracting the spring force of the capping seal against the print head of the spare print cartridge.
