摘要:
A recording apparatus for recording by discharging plural kinds of ink from the recording head to a recording medium comprises detection device for detecting the decrease of ink remains of each ink of the plural kinds of ink, ink amount indication device arranged in a number smaller than the number of the plural kinds of ink, and signal outputting device for outputting signals which enables the decrease of ink remains having the least amount of ink remains to be displayed on the ink amount indication device in accordance with the results of plural detections by the detection device. In this way, only the ink remains having the least ink remains among those kinds of ink in use is indicated on the display, not the ink remains of all the kinds of ink, thus making it possible to minimize the number of indication devices to make the indication device simpler and smaller or minimize the area on the screen of the display assigned for indicating the ink remains in order to save it for indicating more information other than the ink remains.
摘要:
The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank.Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.

A display unit is provided so as to be rotatable with respect to a main body of an electronic apparatus. An inlet for manually inserting a sheet is provided in the vicinity of the center of rotation of the display unit, and a sheet feeding device capable of continuously feeding sheets is provided so as to be detachable with respect to the inlet. It is thereby possible to supply a sheet from the front side of the electronic apparatus.

In a recording apparatus using a plurality of kinds of head cartridges each comprising an ink jet recording head and an ink tank formed as a unit, the present invention prevents, when a wrong head cartridge has been mounted during cartridge exchange, data regarding the remain of ink in a thitherto used cartridge of other kind from being lost, and enables the remain of ink in that cartridge to be confirmed. A user is pressed for the exchange of the head cartridge now mounted to thereby effect the exchange actually, and is called on to confirm whether the newly mounted head cartridge is a right one, and the initialization of the data regarding the remain of ink is effected when the user has done the inputting of the confirmation.
摘要:
An ink jet recording apparatus is provided with at least one first electrode at least in either a recording head or ink retaining member, dielectric adjacent to the first electrode or laying between the first electrodes, a second electrode electrically connected to the first electrode through the dielectric and ink, power supply to apply and release voltage to and from the first electrode, potential difference detector for detecting the potential of the second electrode, and equivalent circuit to determine the ink remains at least in either one of the recording head and ink retaining member in accordance with the potential of the second electrode detected by potential difference detector. In this way, it is possible to provide an ink jet recording apparatus having equivalent circuit for detecting ink shortage, and expect a highly precise detection thereof, and also, to provide information processing systems having such recording apparatus for its output device.
摘要:
An ink jet recording apparatus records using a recording head. The head comprises a plurality of discharge ports for discharging ink, a common liquid chamber for supplying ink to the plurality of discharge ports, and a plurality of discharge elements for causing ink to be discharged from the plurality of discharge ports. The apparatus further comprises driving elements for substantially simultaneously driving said discharge elements corresponding to a first plurality of discharge ports which are not adjacent to each other, among said plurality of discharge ports, and for driving said discharge elements corresponding to a second plurality of discharge ports which are respectively adjacent to said first plurality of discharge ports, not simultaneously with said discharge elements corresponding to said first plurality of discharge ports, but at predetermined intervals within a drive period.
摘要:
A recording apparatus for performing recording on a recording medium with an ink jet recording head capable of ink jetting is described. The recording head is closed by capping after turning off the power source or during waiting or when no data is provided from a host unit for a predetermined period of time. To ensure reliable capping, the position of the carriage carrying the head is recognized. According to the invention, in a case when jumping of teeth occurs in a carriage motor drive system gear due to external disturbance of carriage running, the error that occurs in the carriage position recognition is held within one step so that there is no adverse effect on the capping executed during non-recording time such as when recording is ended or when absorbing recovering is executed.

摘要:
A recording apparatus performs recording with an ink jet recording head that is capable of ejecting ink onto a recording medium. The recording apparatus includes an ink receiving section disposed at a position to be able to oppose an orifice-formed face of the recording head, a preliminary ejection unit for causing ink ejection from discharging orifices toward said ink receiving section by driving said recording head to remove causes of defective ink ejection, an absorption unit for absorbing ink remaining in the ink receiving section as a result of ink ejection by the preliminary ejection unit, and a dry absorption control unit. The dry absorption control unit causes ink absorption by driving the absorption unit when a number of preliminary ejection caused by the preliminary ejection unit, from the time of an absorption previously executed by the dry absorption unit during recording, exceeds a predetermined number.
摘要:
A recording apparatus for performing recording with an ink jet recording head, capable of ejecting ink onto a recording medium, comprises a cap to be opened and closed with respect to a discharge-orifice face of the recording head and a cap drive mechanism for opening the cap at the initiation of recording head driving and closing the cap when a non-driving period of the recording head exceeds a predetermined period of time .alpha.. A preliminary ejection circuit causes ejection of ink from the discharge orifices by driving the recording head to remedy defective ink ejection and preliminary ejection drive circuitry provides for preliminary ejection when a predetermined period of time .beta. is exceeded after a previously executed preliminary ejection, wherein the predetermined period of time .beta. does not include time during which the cap is closed.
