摘要： In a printer (1) of the present invention, an EEPROM (90) that carries out sequential access and has a relatively small storage capacity is applied for storage elements (80) mounted on both black and color ink cartridges (107K, 107F), which are detachably attached to the printer (1). Pieces of information relating to each ink cartridge (107K, 107F), for example, pieces of information on remaining quantities of respective inks in the ink cartridge, are stored in the storage element (80) of the ink cartridge (107K, 107F). A format of addressing adopted in the storage elements (80) of the ink cartridges (107K, 107F) is different from that adopted in an EEPROM (90) incorporated in a printer main body (100) of the printer (17). A control IC (200) provided in the printer (1) accordingly converts the storage format of addressing, before writing the information into the storage elements (80) of the ink cartridges (107K, 107F). In the printer (1), a RAM (210) is mounted with the control IC (200) on a carriage (101), and the pieces of information to be written into the storage elements (80) of the ink cartridges (107K, 107F) are temporarily registered in the RAM (210). The pieces of information are then written into the respective storage elements (80) of the black and color ink cartridges (107K, 107F), for example, at a timing of a power-off operation. The signal lines and the memory used in the course of writing the information into the storage elements (80) are identical with the signal lines, through which print data are transmitted to a print head (10) mounted on the carriage (101) of the printer, and the memory, in which the print data are stored. The arrangement of the present invention reduces the manufacturing cost of the ink cartridge (107K, 107F) and also enables size reduction of the whole printer (1).

摘要： Dot recording technique is provided to relieve deterioration of image quality due to ink blot or deviation of dot density. Recording positions on each pass of main scan are set so that the dot recording positions for an identical color appear once every s dots in a main scanning direction on each raster line where s is an integer of at least 5. A sub-scan feed amount after each pass and the dot recording positions on each pass of the main scan are set so that the dot recording positions on any two consecutive passes are separated from each other.

摘要： An ink-jet recording apparatus having an ink-jet recording head (7, 8) including pressure generating chambers (49) communicatively connected to a nozzle opening (52) and a reservoir (50), pressure generating means (42) for pressurising the pressure generating chambers (49), and control means for applying drive signals corresponding to print data to the recording head and for minutely vibrating meniscuses of ink in the nozzle openings to such an extent as to not eject ink droplets during a nonprint period. The control means ejects ink droplets from the nozzle openings in accordance with print data during printing operations, and minutely vibrates meniscuses of ink formed at the nozzle openings a pre-set period of time before or after the discharging of the ink droplets in a printing operation. Minutely vibrating means (23, 42, 68) are provided having a first operation mode in which the meniscuses of the nozzle openings are vibrated plural times in succession for a predetermined time period, and a drive signal for discharging ink droplets is applied to said pressure generating means after said meniscuses are placed in a state capable of discharging ink droplets.

摘要： An ink cartridge (190) placed in an ink jet printer (500) stores cartridge management data containing "ink capacity", "ink total consumption amount", and "cartridge identification information". A host (100) stores host management data containing "ink total consumption amount" and "cartridge identification information for each cartridge. The host collates the cartridge management data read by the printer (500) with the host management data stored in the host (100) and determines the precise "ink total-consumption amount." After print processing terminates, the printer calculates the amount of ink consumed in the print (ink consumption amount) and the host updates the "ink total consumption amount" based on the calculated ink consumption amount. The printer updates the "ink total consumption amount" recorded in the cartridge management data to the "ink total consumption amount" updated by the host.

摘要： An ink cartridge (107K, 107F) of the present invention has a storage element (80K, 80F), in which plural pieces of specific information relating to the ink cartridge (107K, 107F) are stored at specific addresses having predetermined data lengths. For example, a piece of information on the year of manufacture is registered in a data length of 7 bits, a piece of information on the month of manufacture is registered in a data length of 4 bits, and a piece of information on the date of manufacture is registered in a data length of 5 bits. A piece of information on the time (hour) of manufacture is registered in a data length of 5 bits, and a piece of information on the time (minute) of manufacture is registered in a data length of 6 bits. The technique of the present invention determines whether the storage element (80K, 80F) incorporated in the ink cartridge (107K, 107F)is normal or abnormal, based on the piece of information on the month of manufacture. This arrangement ensures the easy and adequate determination of whether or not the information stored in the storage element (80K, 80F) is destroyed.

摘要： An ink jet recording apparatus is described which jets out a plurality of ink droplets at a predetermined cycle within a single drive period and such that the ink droplets are combined in the air to form a single ink droplet which is supplied to a recording sheet. A charge pulse generating circuit (20) and a discharge pulse generating circuit (22) which divide a drive period into a plurality of segments and output a pulse signal, having cycle Tp which is larger than the Helmholtz cycle Tc, in synchronism with an auxiliary print signal. A time constant adjusting circuit (24) changes an output waveform of a constant current circuit (21, 23) with the pulse signal to increase the velocity of an ink droplet last jet out so that the velocity of the ink droplet allows the ink droplet to be combined, in the air, with an ink droplet previously jet out. It is further described a method for performing ink jet printing with an ink jet recording apparatus.
