As shown, the inkjet printer 10 has a paper feeder 10a for storing media, and a color for injecting ink to perform printing on media fed from the paper feeder 10a. An ink cartridge 10c, a mono ink cartridge 10d which is installed to be advanced by a predetermined length than the total nozzle size of the color ink cartridge 10c, and ejects black ink, and the color ink cartridge And a carrier 10b which mounts the 10c and the mono ink cartridge 10d and performs left and right reciprocating motion.

The color ink cartridge 10c and the mono ink cartridge 10d will be described below with reference to the accompanying drawings.

Fig. 5 is an arrangement structure diagram showing the arrangement of the arrangement of the ink cartridge shown in Fig. 4. As shown, a cyan nozzle 10c-1 for ejecting cyan ink and a magenta nozzle 10c-2 for ejecting magenta ink and yellow ink are ejected. A color ink cartridge 10c having a yellow nozzle 10c-3 to be formed, and a mono ink cartridge having a black nozzle 10d-1 for ejecting black ink ( 10d) and a carrier 10b on which the color ink cartridge 10c and the mono ink cartridge 10d are mounted and which perform left and right reciprocating motion.

Referring to the operation according to the configuration as follows.

First, print data applied from a computer main body (not shown) is applied by the inkjet printer 10. The inkjet printer 10 receiving the print data moves the media stored in the paper feeder 10a to the bottom of the color ink cartridge 10c and the mono ink cartridge 10d according to the applied print data. do. In this way, the inkjet printer executes left and right reciprocating motion to guide the carrier 10b to the main shaft (not shown) in order to eject ink onto the fed medium Media. In this way, the color ink cartridge 10c and the mono ink cartridge 10d attached to the carrier 10b guided to the main shaft and performing left and right reciprocating motions perform ink reciprocating left and right, The ink is dropped into the medium by spraying the ink.

When ink is dropped into the media through the nozzles of the color ink cartridge 10b-1 and the mono ink cartridge 10d, the ink drop is transferred to the media. The result is a print job.

In particular, the mono ink cartridge 10d is brought into contact with the wall surface 10b-1 of the carrier 10b rather than the color ink cartridge 10c, so that one surface of the cyan nozzle 10c01 of the color ink cartridge 10c. And the color ink cartridge 10c and the mono ink cartridge 10d are separated by as much as the line segment AA 'passing through one side of the black nozzle 10d-1 of the mono ink cartridge 10d. It is installed.

Therefore, if there is both color image data and black image data on one line of the media at the same time, the color image data is ejected after the black ink is ejected through the mono ink cartridge 10d. Color image data is sequentially printed through the color ink cartridge 10c.

In other words, after the black ink is ejected and printed through the black nozzle 10d-1 of the mono ink cartridge 10d, the color ink cartridge 10c at the same position of the media. The cyan ink is dropped and printed through the cyan nozzle 10c-1.

As such, when the black and cyan ink are printed, the medium is printed by spraying the magenta ink through the magenta nozzle 10c-2. In addition, when magenta ink is injected, a line is moved through the media to inject yellow ink through the yellow nozzle 10c-3.

By performing the printing operation in this order, the printing speed is improved by using the black nozzles 10d-1 of the mono ink cartridge 10d as a whole.

The circuit of the inkjet printer for driving such a printing mechanism will now be described with reference to the accompanying drawings.

6 is a block diagram showing an internal circuit of the inkjet printer according to the present invention. As shown, a ROM 21 incorporating a color and mono print control program, a bias program and font data, and a color and mono print control stored in the ROM 21. A RAM 22 temporarily stored when a program and a BIOS program are executed, and a color and mono print control program and a bias program stored in the ROM 21 are read to read the RAM 22.

And feed control according to print control signals A line feed driver 25 for outputting a call, a line feed motor 26 rotating to feed media in accordance with a line feed control signal output from the line feed driver 25, and the ASIC 24 A head driver 27 for receiving a color and mono and a print control signal outputted from the head) and outputting a head control signal for controlling the head according to the applied color and mono and print control signals; A color ink cartridge 10c that receives the head control signal output from the head driver 27 and ejects the color ink according to the applied head control signal, and mono according to the head control signal output from the head driver 27. Mono ink cartridge 10d for ejecting mono ink, and color, mono and print control signals applied from the ASIC 24 are applied, and a carriage control signal is output. It is composed of a carriage return (Return) driver 28 and the carriage return (Return) driver 28 a carriage return (Return) motor 29 which is being rotated a carriage control signal outputted from.

Referring to the operation according to the configuration as follows.

First, the CPU 23 receiving print data outputted from a computer main body (not shown) temporarily executes a bias (BIOS) program or font data stored in the ROM 21 in the RAM 22 for execution. In this manner, after the CPU 23 processes the print data, the print control signal that is the result of the processing is output. The printed control signal is applied to each circuit unit through the ASIC 24.

The line feed driver 25 receiving the print control signal output through the ASIC 24 outputs a line feed control signal according to the print control signal. The line feed control signal output from the line feed motor 26 is applied to generate a rotational force. The media is moved to the print position by the generated rotational force applied by the line feed motor 26.

The print control signal output from the ASIC 24 is applied by the head driver 27 to inject ink onto the media moved to the print position, and the head control signal is output according to the applied print control signal. The color ink cartridge 10c and the mono ink cartridge 10d, which are applied with the output head control signal, divide the ink through the nozzle according to the applied head control signal to print on the media.

As such, when the print job is completed on one line of the media, the print control signal applied from the ASIC 24 is received by the carriage return driver 28 and the carriage control signal is applied according to the applied print control signal. Will print. The carriage return motor 29 receiving the output carriage control signal moves one line of the media according to the applied carriage control signal to print the next line print data.

At this time, if the color print data and the mono print data simultaneously exist in one line of print data, the CPU 23 reads the color and mono print control programs stored in the ROM 21 ( To be temporarily stored in the RAM 22 for execution. The color and mono print control signals generated as a result of the execution are applied to each circuit section through the ASIC 24.

As such, the head driver 27 receiving the color and mono print control signals applied through the ASIC 24 transmits the applied color and mono print control signals to the color ink cartridge 10c and mono. ) Is applied to the ink cartridge 10d. The mono ink cartridge 10d, which has received the color and mono print control signals, receives the black nozzle 10d-1 (shown in FIG. 5) according to the applied mono print control signal. Black ink is sprayed through to print on the media.

When black ink is ejected through the mono ink cartridge 10d, the cyan ink is again passed through the cyan nozzle 10c-1 (shown in FIG. 5) of the color ink cartridge 10c. By spraying the print job to the media (Media).

As such, when the black ink and the cyan ink are injected, the carriage return driver 28, which receives the color and mono print control signals output from the ASCI 24, receives the applied color and the color. The carriage control signal is output in accordance with the mono print control signal. The carriage return motor 29 receiving the output carriage control signal moves one line of the media according to the applied carriage control signal.

When one line of the media is moved, magenta ink is sprayed through the magenta nozzle 10c-2 of the color ink cartridge 10c. Also, as in the magenta nozzle 10c-2, the media is moved again one line, and yellow ink is sprayed onto the media through the yellow nozzle 10c-3. Done.

In this way, the mono ink cartridge 10d and the color ink cartridge 10c are configured such that they do not coincide with each other to print the mono print data and the color print data so that the color image data and the mono image are printed. When printing the print data in which the print data is mixed, the print speed is improved.

Therefore, in the inkjet printer employing the two ink cartridges, when the black image data and the color image data are simultaneously present on the same line, the entire nozzle of the black ink cartridge is removed when printing the black data. By using it to print, there is an effect that can improve the printing speed.
