Abstract
An image forming apparatus including a body, a print head including a nozzle part having a length corresponding to a width of a printing medium, and a regulator provided separately from the print head and mounted to the body, the regulator serves to adjust a negative pressure of ink which is to be supplied into the print head.
Claims26
An image forming apparatus, comprising:
- a body;
- a print head including a nozzle part having a length equal to or greater than a width of a print medium and detachably mounted onto the body;
- an ink tank mounted onto the body to store the ink which is to be supplied to the print head;
- and
- a regulator provided apart from the print head and the ink tank and mounted onto the body even when the print head is detached from the body, the regulator to adjust a negative pressure of ink as it flows through the regulator to be supplied to the print head when the print head is attached to the body.
2 more elements
An image forming apparatus, comprising:
- a body;
- a print head including a nozzle part having a length greater than or equal to a width of a print medium;
- a cradle pivotally and/or rotatably mounted in the body to receive the print head when mounting the print head to the body;
- an ink tank provided apart from the print head and mounted to the body even when the print head is detached from the body, in which ink is stored;
- and
- a regulator provided apart from the print head and mounted in the body, the regulator to adjust a negative pressure of the ink which is to be supplied from the ink tank to the print head when the print head is attached to the body.
3 more elements
A printhead usable with an image forming apparatus having an ink tank and/or a regulator, the printhead comprising:
- a first ink supply connector which includes a first valve member accessible through a first orifice within the first ink supply connector, the first valve member being movable between a first position and a second position, the first position prevents ink communication between the printhead and the ink tank via the first ink supply connector and the second position allows ink communication between the printhead and the ink tank via the first ink supply connector, such that an insertion of the printhead onto the image forming apparatus provides ink communication between the printhead and the image forming apparatus;
- a second ink supply connector coupled to the image forming apparatus to mirror the first ink supply connector, comprising a second valve member accessible through a second orifice;
- and
- a flow-path connecting device slidably attached to the first ink supply connector, the flow-path connecting device comprising at least one connecting tube having a first end inserted into the first orifice and a second end inserted into the second orifice to attach the print head to the body.
1 more element
A method of manufacturing an image forming apparatus, the method comprising:
- disposing a body having a receiving unit coupled with the body, a receiving space, and a first connector installed in the receiving space and having a first orifice;
- disposing a print head detachably installed in the receiving space and including a head chip to eject ink and a second connector having a second orifice corresponding to the first orifice of the first connector;
- disposing a flow-path connecting device installed between the first connector body and the second connector body, comprising a flow-path tube having a first end inserted into the first orifice and a second end inserted into the second orifice to attach the print head to the body;
- and
- disposing a regulator to adjust a negative pressure of the ink as it flows through the regulator to be supplied to the print head when the print head is attached to the body,
- the first connector and the second connector connecting to each other as the print head is inserted into the receiving space.
3 more elements
An image forming apparatus, comprising:
- a body comprising at least one first connector body having at least one first orifice;
- a print head, comprising:
- a nozzle part having a length equal to or greater than a width of a print medium, and
- at least one second connector body having at least one second orifice to correspond to the at least one first orifice;
- a flow-path connecting device installed between the first connector body and the second connector body, comprising a flow-path tube having a first end inserted into the first orifice and a second end inserted into the second orifice to attach the print head to the body;
- and
- a regulator to adjust a negative pressure of ink which is to be supplied to the print head from an ink tank when the print head is attached to the body, the print head being removable from the body without removing at least one of the ink tank and the regulator.

An image forming apparatus, comprising:
- a body;
- a print head including a nozzle part having a length greater than or equal to a width of a print medium;
- a regulator mounted on the body to adjust a negative pressure of ink which is to be supplied the print head when the print head is attached to the body;
- and
- a cradle pivotally and/or rotatably mounted on the body to allow the print head to couple to and detach from the body without attaching or removing the regulator from the body.
