摘要:
An ink jet recording apparatus including a heating member for heating a recording medium in order to accelerate the fixation and adhering of liquid ink being discharged from a recording head onto the recording medium, wherein the heating of the recording medium promotes the evaporation of the liquid ink but creates moisture in the area of the recording head. A moisture condensation preventing member positioned near the recording head decreases the moisture in the vicinity of the recording head. This prevents condensation of this moisture on the recording head, which can lead to faulty recording.

A liquid-discharge recording apparatus such as an ink-jet printer comprises: a liquid-discharge recording unit having an emission energy generating device including an electrothermal energy converting device which can heat a recording liquid such as an ink to form liquid droplets in response to an electrical signal, in which this recording unit emits the liquid droplets and deposits them on a recording paper and thereby recording thereon; a recording unit control circuit which can set and supplies the electrical signal to form the liquid droplets to the emission energy generating device in response to a recording signal; and an emission controller for setting the electrical signal to form the liquid droplets to the recording unit control circuit when a power supply is turned on, thereby allowing the recording unit to emit the liquid droplets in accordance with an environmental condition such as a temperature of the recording liquid. With this dedicated emission controller, the proper emission condition is set and the preheating processes and preliminary emitting processes are executed prior to starting the printing after the turn-on of the power supply of the printer, so that the printing state can be promptly and easily optimized by a simple software.

摘要:
Provided is an ink-jet recording process for forming a color image on a recording medium using a liquid formulation and a color ink in combination, wherein the liquid formulation contains a cationic polymer having a weight-average molecular weight in the range of from 400 to 1,400, and the liquid formulation and the ink are each ejected from a recording head having an ink ejection volume per dot of from 2 to 25 picolitters.
摘要:
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.

An ink jet cartridge has a recording head portion and an ink containing portion which are detachably mountable relative to each other. The recording head portion ejects ink to effect recording with the ink. The cartridge includes a first ink container, provided in the recording head portion, for containing the ink; a second ink container, provided in the ink containing portion, for containing the ink; and an ink communication tube for establishing ink communication between the first ink container and the second ink container, wherein the ink communication tube is not externally exposed. An ink jet recording apparatus includes a recording head for ejecting ink, an ink container detachably mountable to the recording head for containing the ink to be supplied to the recording head, a detecting device for detecting mounting of the ink container to the ink jet recording apparatus and a control device for controlling a recording operation of the ink jet recording apparatus in accordance with an output of the detecting device.
摘要:
An ink jet recorder comprises a first tank as an ink supply source, a second tank as an ink supply source for the first tank, and three switching means and a pump arranged in an ink supply path. By controlling open/close states of the switching means and operation condition of the pump, print mode, supply mode, pressure mode, circulation mode or store mode can be selectively established.
