ABSTRACT:
CLAIM OF PRIORITY
This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 arising from an application for THE INKJET PRINTER USING EXCHANGE OF INKHEAD FOR SCANNER OF CARRIAGE earlier filed in the Korean Industrial Property Office on Dec. 12, 1997 and there duly assigned Ser. No. 68381/1997.
FIELD OF THE INVENTION
The present invention relates to an ink jet printer, and more particularly to an ink jet printer capable of scanning a document, in which a scan module is mounted on a carriage instead of one of ink cartridges, for examples color ink cartridges and mono ink cartridges, mounted on the carriage. Further, the present invention relates to an ink jet printer capable of preventing the scan module from being polluted by a cap mounted in a capping section when the scan module is mounted therein.
DESCRIPTION OF THE PRIOR ART
Generally, an ink jet printer is an apparatus for printing data transferred from a computer on a recordable paper, which has one or more than one ink cartridges mounted on a carriage. Ink jet printers can be combined with a scanner to form a device that can either scan a document or print a document. What is needed is an ink jet printer that can have a scanning module replace one of the ink cartridges allowing an ink jet printer to operate as a scanner.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an ink jet printer for having a plurality of ink cartridges and at least one scan module mounted detachably on a carriage.
It is another object of the present invention to provide an ink jet printer in which a carriage is positioned in a capping section when a printing or scanning is finished in a case that a scan module is mounted in the ink jet printer.
It is still another object of the present invention to provide an inkjet printer in which a scan module is prevented from being polluted by a cap mounted on a capping section in a case that the scan module is mounted in the ink jet printer.
To accomplish the above object of the present invention, there is provided an ink jet printer for having a scan module detachablly thereon, having:
a body including a paper carrying section and a capping section formed at an outside of the paper carrying section;
a guide shaft mounted to be normal to a direction of carrying the paper along a width of the body;
a carriage having a plurality of ink cartridges mounted thereon, which is reciprocally moved along the guide shaft in the paper carrying section, and which is carried to the capping section when a printing or scanning operation is finished; and
a scan module that is detachably mounted on the carriage and a distance between the scan module and the capping section is larger than a distance between the ink cartridges and the capping section.
The scan module is spaced from the capping section not to be contacted with a cap mounted in the capping section to prevent ink in nozzles of the ink cartridge from being dried.
The scan module can be mounted on the carriage instead of one of the plurality of the ink cartridges.
The cable for applying a predetermined signal to the scan module and the plurality of the ink cartridges includes private connectors which are respectively connected to each ink cartridge and common connectors which are connected to the scan module.
The scan module is basically the same size as one of the ink cartridges.
