A replaceable ink cartridge can be inserted into and removed from a bubble jet printer receptacle for removably mounting the cartridge. The cartridge when mounted will cooperate with a hollow needle for supplying liquid ink to a print head and a pipe for removing waste ink from the head. The cartridge includes a container, a liquid ink reservoir and an absorber for waste liquid ink in the container, an outlet and an opening on the front wall of the container, and a label secured to the top wall of the container. The label contains a surface wiring resistance pattern including contact portions which are spaced apart and have an electric connection between them. When the container is mounted in the receptacle, the needle enters the outlet to connect the ink reservoir to the head, and the absorber enters a waste ink pipe opening. The contact portions then make sliding contact with spaced-apart electric terminals in the printer, connecting the terminals and thereby activating a control circuit in the printer.

An ink container includes a container body and a movable wall movable along an inside surface of the container body. The movable wall comprising has a sealing portion in sealing contact with the inside surface of the container body and at least one tilt preventing portion for preventing the movable wall from tilting. The tilt preventing portion is spaced from the sealing portion.

An ink jet recording apparatus is designed to prevent leakage of ink from an ink tank cartridge with recording ink stored therein when the cartridge is removed. A flexible ink bag is sandwiched between an upper plate and a lower plate so that the-upper plate can be moved as the ink bag contracts as the ink is consumed. When the ink is almost gone, the upper plate is held by a latch on the lower plate, and movement of the ink bag is suppressed. Leakage of ink from a stopper that provides access to the ink bag is prevented by sealing members on the upper and lower plates. Thus, when the cartridge is replaced, no ink will be applied.

Three discharge port groups, each having a plurality of discharge ports, discharge inks of three primary colors to record swaths of the respective colors on a recording medium and repeat the discharging to complete a record. Joints of each of Y, M and C color swaths are spaced from joints of swaths of the other two colors by an equal distance, and the discharge port groups are offset from each other by 8n times of a discharge port pitch in a direction of feed of the recording medium. In a number of image buffers corresponding to the discharge ports, image data in one buffer is separated from image data in a different image buffer by an amount that is an integer multiply of one 8 bit byte.

A liquid-discharge recording apparatus includes a recording head, an emission signal generator, and a heating signal generator. The recording head includes electrothermal energy converting elements for generating energy used to emit liquid in response to an emission signal from an emission signal generated by the emission signal generator. The heating signal generator generates an electrical signal applied to the electrothermal energy converting elements of sufficient level for heating the liquid, without discharging, during a first heating mode when power is supplied to the apparatus and for generating an electrical signal during a second heating mode, subsequent to the first heating mode, when recording begins after an interruption in power supply. In addition, a controller is provided for controlling a heater such that the heater is deactivated when the discharge opening of the recording head is capped. A liquid-discharge recording method is applied to the liquid-discharge recording apparatus.
