Problems solved by technology

[0011] However, in the method of the above-mentioned conventional example in which the power saving mode such as split recording is switched only when the number of recording points exceeds a predetermined amount, it is usually difficult to efficiently use the power within the allowable range of power usage.
That is, since the power saving mode is switched to even when the number of points slightly exceeds the threshold value, practically, almost no available power supply capacity close to the maximum capacity is used, and there may be cases where the requirement cannot be fully satisfied by only greatly increasing the recording time.
[0012] In addition, if the drive motor for recording and scanning the recording head is stably driven in a wide range from high speed to low speed without exceeding the maximum capacity of the power supply by reducing the speed of recording and scanning, then From the perspective of motor performance, it is very difficult

Embodiment 1

[0044] Based on the above structure, the first embodiment of the present invention will be described. In this embodiment, a recording mode in which recording is performed only in black is explained. In detail, the number of black dots actually recorded is counted for each of a plurality of blocks divided into regions on the recording medium corresponding to the arrangement width of the black nozzles that can be recorded by one scan of the recording head. Based on the results, the recording method (specifically, the scanning speed and the number of scanning of the recording head) is determined.

[0045] FIG. 4 is a schematic diagram illustrating a block used for dot counting, and shows the internal condition of the print buffer for black. The print buffer stores black recording data corresponding to the area that can be recorded by one scan of the recording head. The black recording data is composed of binary data indicating the ejection of black ink and binary data indicating non-...

Embodiment 2

[0072] In this embodiment, a case where the printer prepares a plurality of recording modes according to the type and quality of the recording medium will be described. In addition, this embodiment also describes the case of recording in black only as in the first embodiment. However, this embodiment can also be applied to the case of recording multiple colors as in the later-described embodiment 3.

[0073] In the printer of this embodiment, two types of recording media, medium A and medium B, can be supported, and two recording modes of "standard" and "clear" can be set for each medium.

[0074] FIG. 9 is a table of threshold values ​​set in each recording mode, and FIG. 10 is a table of recording methods set in each recording mode.

[0075] In FIG. 9, the standard mode of medium A has three-stage thresholds of Stha1, Stha2, and Stha3, and the clear mode has two-stage thresholds of Sthb1 and Sthb2. In addition, the standard mode of medium B has two-stage thresholds of Sthc1 and ...

Embodiment 3

[0089] This embodiment describes not only black recording, but also red, cyan, and yellow recording. In this embodiment, for each of a plurality of blocks divided into regions on the recording medium corresponding to the array width of the nozzles of each color that can be recorded by one scan of the recording head, the number of each color dot actually recorded is The number is counted, and the recording method (specifically, the scanning speed and the number of scanning of the recording head) is determined based on the result.

[0090] FIG. 12 is a schematic diagram illustrating a block used for black and color dot counting, showing the internal conditions of the print buffer for each color of CMYK. In each of these CMYK print buffers, CMYK recording data corresponding to the area that can be recorded by one scan of the recording head is stored. The CMYK recording data is composed of binary data indicating the ejection of CMYK ink and binary data indicating non-ejection.

Abstract

The present invention provides a recording device that can maximize the use of power supply capacity without reducing the amount of operation more than necessary. Therefore, the number of data indicating recording is detected for each of a plurality of blocks obtained by dividing an area recordable by one scan of the recording head. Then, the detected value is compared with a plurality of thresholds. Based on the comparison result, the scanning speed of the recording head and the number of recording scans are determined. As a result, even when an image is to be recorded by flowing a current exceeding the maximum capacity of the power supply, the most suitable recording method can be selected from a plurality of scanning speeds and divided recording formats, so that the maximum possible operation can be achieved without reducing the amount of operation as much as possible. Recording is performed with limited utilization of power supply capacity.

Description

Technical field [0001] The present invention relates to a recording device, and in detail, to a recording device having a structure that effectively utilizes the power supply capacity of the device, a control method of the recording device, and a program. Background technique [0002] With the spread of information processing equipment such as copiers, word processors, computers, and communication equipment, as one of the image forming (recording) devices that output information such as characters and images processed by these equipment, inkjet methods have become popular. Digital image recording device. In the inkjet recording apparatus, in order to increase the recording speed, etc., as a plurality of recording elements, a recording head integrated with a plurality of ink ejection ports and liquid paths is generally used. [0003] In inkjet recording apparatuses, there is also a great demand for a serial printer that is inexpensive and easy to miniaturize as a personal device. ...
