Abstract: A liquid container for a liquid jet recording apparatus includes a first chamber containing negative pressure producing material and having a liquid outlet. At a lower part of the cartridge and contactable to the liquid jet head, the liquid container supplies liquid from the cartridge to the liquid jet head. An air vent allows ambient air into the cartridge. A second chamber communicates with the first chamber by means of a communication part, except for which the second chamber is substantially hermetically sealed. The second chamber is disposed at the lower part of the cartridge and provides a liquid reservoir for the first chamber. Ambient air is introduced through an air path substantially free of negative pressure producing material, having an inlet in the first chamber separated from the air vent by the negative pressure producing material, and an outlet arranged to be lower than the inlet during use of the cartridge to enable air to be supplied to the second chamber through the negative pressure producing material and the air path as liquid is withdrawn from the liquid outlet.

Abstract: A method of exchanging a waste ink pack that stores waste ink discharged by repeated ink clearing operations performed on an ink jet head involves comparing a cumulative number of times the ink clearing operation have been performed using a particular waste ink pack with upper limit data based on the capacity of the waste ink pack. When the cumulative number reaches the upper limit data, an indication is provided that the waste ink pack should be exchanged for a new one, after which exchange a previous instruction to a recovery device to perform an ink clearing operation is performed. Ink clearing operations are then repeated with that waste ink pack until the number of such operations again reaches the upper limit data.

Abstract: A printer having a disposable print head which contains a consumable ink supply includes the capability of determining the level of ink in the print head without directly measuring the ink supply. The print head includes a number of resistors which can be driven to an open circuit condition by the printer. The printer includes a counter and memory for tracking the usage of the print head and a driver for selectively driving the print head resistors to an open circuit condition based upon such usage. The printer is also capable of detecting the condition of the resistors on the print head and producing a resultant visual display.

Abstract: An ink jet recording apparatus which includes a recording head communicated via an ink supply needle with an ink tank and including electrodes for detecting a remaining amount of ink and being responsive to a print signal for spouting ink drops to recording paper, a capping unit abutting against the front of said recording head for holding the nozzle openings in an airtight state, a suction pump for supplying negative pressure to the capping unit, a resistance value detection circuit for detecting electric resistance across the electrodes for detecting a remaining amount of ink, a reference value storage unit for storing a resistance value across the electrodes relative to the remaining amount of ink in the ink tank, a resistance value comparison unit for comparing the resistance across the electrodes with the reference value, and a pump control unit responsive to the resistance value comparison result for controlling a pulse motor driving the suction pump. The resistance value detected by the resistance value detection circuit is compared with the reference value stored in the reference value storage unit to determine whether or not an ink tank is mounted, remounted, how much ink is in the ink tank, etc. Based on the determination result, the motor is controlled by the pump control unit for selecting the suction mode of ink from the recording head.

Abstract: The ink level sensor of the invention comprises an ink container having a generally cylindrical shield extending downward from its top to define shielded and unshielded compartments within the container. Ink, but not foam, froth or mist, flows under the shield to the shielded compartment. A plurality of conductive rods of differing length extend downwardly into the shielded compartment from the container top. The rods are connected to an impedance network which provides signals representative of the ink level inside the container. A vacuum source can be connected to each compartment to maintain pressure equilibrium in the compartments and to prevent foam, froth or mist from entering the shielded compartment. Alternatively, a return pump is used to force ink into the container such that each compartment can be vented to the atmosphere.

Abstract: A liquid ejecting apparatus includes: a container that contains a liquid having conductivity; an electrode bar that is disposed inside the container and that includes a first terminal, a second terminal, and a first insulating section that electrically insulates the first terminal from the second terminal; a detection section that detects a remaining amount of liquid contained in the container in accordance with an electrical signal from at least one of the first terminal and the second terminal; and a liquid ejection head that discharges the liquid supplied from the container. The remaining amount of liquid detected by the detection section when the first terminal is electrically coupled to the second terminal via the liquid in the container is larger than the remaining amount of liquid detected by the detection section when the first terminal is not electrically coupled to the second terminal via the liquid in the container.
