Abstract: An ink storage module includes an ink flow control device and an air chamber. The ink storage module is accessible to an ink tank and an air-extracting device. The ink flow control device includes an ink storage chamber and a pressure control mechanism. The ink storage chamber is used for receiving and storing ink conveyed from the ink tank. The pressure control mechanism is connected to the ink storage chamber for controlling the connection of an external pressure to the ink storage chamber. The air chamber is disposed at a side of the ink flow control device and is accessible to the ink storage chamber. The air chamber is used for exhausting air extracted by the air-extracting device. When the pressure control mechanism controls the ink storage chamber to cut off the external pressure, the air-extracting device drives ink to flow from the ink tank to the ink storage chamber.

Abstract: A printer capable of controlling position of covering a nozzle of an ink cartridge includes a housing, a shaft installed inside the housing, a carriage installed on the shaft in a sliding manner for carrying a first ink cartridge, a first cover for covering a nozzle of the first ink cartridge, and a means for determining type of the first ink cartridge and controlling stopping position of the carriage and the first cover after the first cover covers the nozzle of the first ink cartridge according to the type of the first ink cartridge.

Abstract: Inkjet printers are provided. An inkjet printer includes a maintenance module, an inkjet unit, a pump, a slider, and a swing gear assembly. The swing gear assembly is connected to a motor of the pump and detachably engaged with the slider. When the motor rotates the swing gear assembly in a first direction to a first angle, the swing gear assembly is engaged with the slider, and the swing gear assembly impels the slider from an initial position to a first position to open the valve. When the motor rotates the swing gear assembly in a second direction to a second angle, the swing gear assembly is engaged with the slider, to separate the slider from the first position and close the valve.

Abstract: A plurality of blades on a printhead wiper is used for wiping out the residual ink on the printheads having different length. The printhead wiper deforms when wiping out the residual ink on the printheads, allowing a first blade for wiping the long black print head and a second blade for wiping the short color print head. A disadvantage that the first blade having long length cannot completely cover and wipe the color printhead since the UV glue that fixes the color printhead withstands a portion of the first blade can be solved with the second blade having short length.

Abstract: Inkjet printers are provided. An inkjet printer includes an ink tank, an inkjet unit, a first slider, and a cam mechanism. The inkjet unit includes a reservoir, and the reservoir has a first valve with the first slider movably connected thereto. Ink is transferred from the ink tank to the reservoir when the first valve is open. The cam mechanism includes a shaft and a first cam fixed thereto. When the cam mechanism rotates to a first position, the first cam impels the first slider in a first direction and opens the first valve.

Abstract: A paper ejection apparatus of a multifunctional business machine having a driving wheel installed on a rotatable inner door allows the driving wheel to move with the inner door, and therefore provides sufficient space for cartridge replacement when the inner door is opened. A height difference between a platform and an end of a slit of the housing of the multifunctional business machine allows the driving wheel and an exit roller to have an interfering pre-stress in between when the inner door is closed. The driving wheel is not interfered by the exit roller when the inner door is opening, which prevents the driving wheel from deviating, imprecise homing, or even falling when the inner door is opening or closing.

Abstract: A print head maintenance device. During maintenance, excess ink dispersed from the print head is collected in a collection device. A shuttle moves with the print head in a first direction, with a wiper moves in a second direction wiping remaining ink from the print head. The shuttle returns to an initial position at which time ink collected in the collection device is drained out and absorbed by an absorber.

Abstract: A maintenance device used for cleaning a print head of an ink cartridge includes a maintenance module including a base, a cap for capping the print head of the ink cartridge, and a cap sled installed on the base in a sliding manner for driving the cap upwards to cover the print head of the ink cartridge. A rack is installed on an end of the cap sled. The maintenance device further includes a pump module for pumping the ink out of the print head of the ink cartridge. The pump module includes a pump gear engaged with a feed gear, a swing gear engaged with the pump gear, and a swing gear when the feed gear drives the pump gear and the pump gear drives the swing arm.

Abstract: A printer capable of controlling position of covering a nozzle of an ink cartridge includes a housing, a shaft installed inside the housing, a carriage installed on the shaft in a sliding manner for carrying a first ink cartridge, a first cover for covering a nozzle of the first ink cartridge, and a means for determining type of the first ink cartridge and controlling stopping position of the carriage and the first cover after the first cover covers the nozzle of the first ink cartridge according to the type of the first ink cartridge.

Abstract: A reproducing apparatus and a retractable feeding apparatus thereof. The reproducing apparatus comprises a body and a retractable feeding apparatus. The body comprises a feeding portion and a feeding opening formed on the feeding portion. The retractable feeding apparatus has a tray movable between a retracted position and a stretched position. The tray includes a rotation shaft and a supporting surface. When the tray is disposed in the retracted position, the tray is received in the feeding portion, and the supporting surface faces the feeding portion. When the tray is disposed in the stretch position, the tray is rotatable between a retracted angle and a feeding angle by the rotation shaft, and the supporting surface aligns to a feeding opening in the feeding angle.

Abstract: A capping device for capping a print head of a printer includes a cap for capping the print head, a supporting structure for mechanically engaging and disengaging the cap with the print head, and an elastic structure installed inside the cap. The top of the cap is lower than the top of the elastic structure. Before the supporting structure engages the cap with the print head, the top of the elastic structure bends outward and contacts the print head in an incomplete sealed manner.
