Then, an ink droplet is ejected by the heat generation function, or a liquid is heated by an electrothermal converter having a heat generating resistor. Among them, an ink jet type recording head that discharges ink as droplets by using thermal energy can perform high-resolution recording because discharge ports can be arranged at high density. In particular, among them, a recording head using an electrothermal transducer element as an energy generating element can be easily miniaturized, and IC technology and micro-machining technology, which are remarkable in recent advances in technology in the field of semiconductors and remarkable improvement in reliability.

The value at the right end position is pulled from the recording material table section 12 based on the recording material type and the states “0” and “1”. Then, in step S12, it is determined whether or not the value being pulled matches the value in the right end position storage unit 11. At the time of the judgment, it is regarded as coincidence including a slight error. If they do not match, the flow returns to step S10 to discharge the paper, and then returns to step S3 to repeat the above-described steps. On the other hand, if they match, step S1
Proceed to 3. In step S13, the CPU unit 1 gives a recording instruction to the recording control unit 6, and performs a recording operation.

Next, the operation of the second embodiment of the line head type recording apparatus to which the present invention is applied will be described with reference to the flowcharts of FIGS. 24, 25 and 26. Here, FIG.
And FIG. 25 shows a main routine connected to each other by reference characters T, U, V and W, and FIG. 26 shows a step S3 in FIG.
8 is a subroutine of an ejection check process. In FIG. 24, when the power is turned on, the recording apparatus is in an operable state (step S21). Then, the process proceeds to step S22, where the recording history storage unit 2 stored in the nonvolatile state
"0" or "1" of each recording material type is transmitted to the recording material display control unit 3, and the recording material display unit 4 is turned on. If the power is turned on for the first time, the light is turned on as in the initial display state shown in FIG.

In a step S23, the CPU section 1 sets the I / F
It is determined whether or not there is a recording instruction from the PC through the unit 13.
When there is a recording instruction, the process proceeds to step S24, and when there is no recording instruction, the process proceeds to step S25. If there is no recording instruction and the process proceeds to step S25, in this step, the CPU 1 determines whether or not there is a line head check instruction from the PC through the I / F unit 13. Proceed to step S26,
If there is no line head check instruction, step S23
Then, the above operation is repeated. On the other hand, if there is a recording instruction in step S23 and the process proceeds to step S24, the CPU 1 interprets the transmitted recording instruction and sets the recording material type in the recording material type storage unit 5 in this step. Is done.

If there is the line head check instruction and the process proceeds to step S26, the process proceeds to step S26.
The PU unit 1 sends a line head check instruction to the recording material / ejection detecting unit 21 and the recording material / ejection detecting unit 2
1 measures the recording material width, and the result (recording material width) is set in the recording material width storage unit 10.

When the type of the recording material is set in the recording material type storage section 5 in step S24, the process proceeds to step S27. In step S27, the CPU 1 issues an instruction to measure the width of the recording material. The recording material / ejection detecting unit 21 measures the width of the recording material and the right end position, and sends the result to the CPU unit 1 so that the recording material width is stored in the recording material width storage unit 10. And the right end position is set in the right end position storage unit 11. In the next step S28, the CP
The operation of the U unit 1 checks whether the value of the recording material width is not 0. If the value is 0, it is determined that there is no recording material, and the process proceeds to step S29. Is performed, and the process returns to step S23 to repeat the above-described steps. on the other hand,
If it is not 0, the process proceeds to step S30.

In a step S30, the CPU 1 stores the recording material table 1 based on the contents of the recording material type storage 5.
The value of the corresponding paper width (recording material width) 2 is pulled. In step S31, the CPU 1 determines whether or not the pulled value matches the value in the recording material width storage 10. At the time of the judgment, it is considered that they coincide with a slight error. If they do not match, the process proceeds to step S32, where the CPU unit 1 instructs the recording control unit 6 to discharge the paper (recording material), and after discharging the paper, proceeds to step S2.
3 and repeat the above steps.

On the other hand, if they match, the process proceeds to step S33. In step S33, by the operation of the CPU unit 1,
Based on the recording material type in the recording material type storage unit 5, “0” or “1” indicating the history state of the same recording material type in the recording history storage unit 2 is extracted, and the recording material type and this state are extracted. Recording material table unit 1 based on “0” and “1”
The value at the right end position is pulled from 2. Then, in a step S34, it is determined whether or not the value being pulled matches the value in the right end position storage unit 11. At the time of the judgment, it is regarded as coincidence including a slight error. If they do not match, the flow returns to step S32 to discharge the paper, and further returns to step S23 to repeat the above steps. If they match, the process proceeds to step S35. In step S35, the CPU unit 1 gives a recording instruction to the recording control unit 6, and performs a recording operation.

After the recording operation, in step S36, the state of the same recording material type in the recording history storage unit 2 is changed from "0" to "1" based on the recording material type in the recording material type storage unit 5. Or, change from “1” to “0”. Next, the process returns to step S22 in FIG. 24, and the recording material display unit 4 is turned on in accordance with the changed contents of the recording history storage unit 2. In this case, for example, the display is changed to the display after recording as shown in FIG. 19, which shows the display state after recording A4 landscape in the initial display state of FIG. Then, in step S23, the process waits for the next recording instruction.

In step S25, there is a line head check instruction, and the flow advances to step S26.
At 26, the recording material width is measured by the recording material / ejection detection unit 21. If the result (recording material width) is set in the recording material width storage unit 10, then the process proceeds to step S37. In step S37, it is checked whether or not the recording material width is the largest by the operation of the CPU unit 1. Therefore, if the recording material width is not the maximum, the process proceeds to step S32 to discharge the recording material, and then returns to step S23 to repeat the above steps. On the other hand, if the recording material width is the maximum, the process proceeds to step S38, where the ejection check process (subroutine) described below is performed.

Here, the operation (subroutine) of the ejection check processing in step S38 will be described with reference to FIG. In FIG. 26, in step S38-1, C
The PU unit 1 gives a check pattern recording instruction to the recording control unit 6, and a check pattern recording operation is performed. In the next step S38-2, the CPU section 1 gives a recording material reverse feed instruction to the recording control section 6 to check whether or not the recorded check pattern is abnormal, and reverses the recording material. I do.

Next, in step S38-3, C
The PU unit 1 sends an ejection failure detection instruction to the recording material / ejection detection unit 21 and inspects the recorded check patterns in order from the right end by the recording material / ejection detection unit 21. The result is sent to the CPU unit 1, and the position of the abnormal part is set in the abnormal position storage unit 22. In the next step S38-4, by the operation of the CPU section 1, it is checked whether or not each recording material type can take a recording material width avoiding an abnormal position by the following method, and the result is recorded. It is set in the material table 12. That is, the CPU unit 1
Checks the types of recording materials listed in the recording material table 12 in the following flow.

First, it is checked whether or not the A1 vertical "0" state is recordable. If the width from the current right end position to the abnormal position on the left side is larger than the width of the recording material, recording is possible. In that case, the right end position is left as it is, and the process proceeds to the next A1 vertical "1" state check. If the width from the current right end position to the left abnormal position is smaller than the width of the recording material by such a check, the width of the recording material between both ends of the recording material and the adjacent abnormal position to the left and right of each abnormal position. It is checked in order of the left side and the right side whether or not it can be taken. This check is
It is performed cyclically in order from the abnormal position on the left side of the current right end position. If the recording material width can be obtained by the above check,
If it is to the left of the abnormal position, the abnormal position is set as the right end position. If it is to the right of the abnormal position, a value obtained by subtracting the recording material width from the abnormal position is set as the right end position. On the other hand, if the width of the recording material cannot be obtained, “none” is set for both the right end position and the character position.

Next, similarly, it is checked whether or not the "1" state of A1 length is recordable, and the result is set at the right end position and the character position. Then, from the contents of both the “0” state and the “1” state in the A1 vertical direction, if only one of them can be recorded, the value is applied to the other. Similarly,
The recording material type (paper type) is checked one after another, and the result is set in the recording material table 12 (FIG. 22). When the B4 vertical check is completed, the discharge check is completed.

In step S38-5, the CPU 1 instructs the recording controller 6 to discharge the recording material (paper), discharges the recording material, returns to the main routine of FIGS. 24 and 25, and returns to FIG. Return to step S22. Step S22
Then, the type of the recording material and the right end position at which the recording can be performed while avoiding the abnormality of the line head 7 are displayed on the recording material display section 4. Then, the process proceeds to step S23 (FIG. 24) and waits for the next recording instruction. Repeat the above steps.

In the above embodiment, an ink jet recording apparatus in which the line head 7 as a recording means (recording head) is an ink jet recording head is exemplified. The same effect can be achieved in a recording apparatus using another recording method such as a beam type, and the same effect can be achieved. Also, the present invention provides a recording apparatus using one recording head, a color recording apparatus using a plurality of recording heads for recording in different colors, or a gradation recording apparatus using a plurality of recording heads for recording the same color at different densities. , And even in the case of a recording device of a system combining these,
It can be applied similarly and can achieve the same effect.

Further, in the case of an ink jet recording apparatus, the present invention uses a replaceable ink cartridge in which a recording head and an ink tank are integrated. The arrangement and the like can be applied to any arrangement of the recording head and the ink tank, such as the arrangement of connection with the same, and the same effect can be obtained.

[0002]

2. Description of the Related Art A recording apparatus having functions such as a printer, a copying machine, a facsimile or the like, or a recording apparatus used as an output apparatus such as a composite electronic apparatus including a computer or a word processor, or a workstation is provided with image information (recording information). The image (including characters, symbols, etc.) is recorded on a recording material (recording medium) such as paper, cloth, plastic sheet, OHP sheet, etc. The recording apparatus can be classified into an ink jet type, a wire dot type, a thermal type, a laser beam type and the like according to a recording method.

In a serial type recording apparatus that performs recording while performing main scanning in a direction intersecting the transport direction (paper feeding direction and sub-scanning direction) of the recording material, a carriage that moves in the main scanning direction along the recording material. An image is formed (recorded) by the recording means (recording head) mounted thereon, and after one line of image formation is completed, a predetermined amount of paper feed (pitch conveyance as sub-scanning) is performed, and then the operation is stopped again. By repeating the operation of recording (main scanning) the image of the next row on the recording material, the recording of the entire recording material is performed.
On the other hand, in a line type recording apparatus that performs recording only in the sub-scanning direction of a recording material (recording paper or the like) in the transport direction, the recording material is set at a predetermined recording position, and recording for one line is performed collectively. After that, a predetermined amount of paper feed (pitch feed) is performed, and further, the operation of collectively recording the next line is repeated, thereby recording the entire recording material.

Among them, an ink jet type recording apparatus (ink jet recording apparatus) performs recording by discharging ink from a recording head (recording means) to a recording material, and it is easy to make the recording head compact. It can record high-definition images at high speed, can record on plain paper without requiring special processing, has low running costs, is non-impact, has low noise, and has many types of It has the advantage that it is easy to form a color image using ink (for example, color ink).

As an energy generating element for generating energy used for discharging ink from a discharge port of an ink jet recording head, an element using an electromechanical transducer such as a piezo element, or heating by irradiating an electromagnetic wave such as a laser. Then, an ink droplet is ejected by the heat generation function, or a liquid is heated by an electrothermal converter having a heat generating resistor. Among them, an ink jet type recording head that discharges ink as droplets by using thermal energy can perform high-resolution recording because discharge ports can be arranged at high density. In particular, among them, a recording head using an electrothermal transducer element as an energy generating element can be easily miniaturized, and IC technology and micro-machining technology, which are remarkable in recent advances in technology in the field of semiconductors and remarkable improvement in reliability. This is advantageous because the advantages of the above can be fully utilized, high-density mounting is easy, and the manufacturing cost is low.

Further, even when an abnormality occurs in a part of the line head, the recording material setting position has been determined for various recording materials irrespective of the abnormal portion.

[0008]

However, in the above-described conventional example in which the recording material setting position is fixed for various recording materials, the recording material having a recording width smaller than the length of the line head is used. Even when recording, since the position of the line head is fixed, there is a problem to be solved in that the degree of deterioration in the recording performance of some line heads becomes more severe than that of other line heads. Further, even when recording is performed on a recording material having a recording width smaller than the length of the line head, a recording defect may occur because the position of the line head is determined independently of the abnormal portion. There were also issues to be solved.

In step S23, the CPU unit 1 sets the I / F
It is determined whether or not there is a recording instruction from the PC through the unit 13.
When there is a recording instruction, the process proceeds to step S24, and when there is no recording instruction, the process proceeds to step S25. If there is no recording instruction and the process proceeds to step S25, in this step, the CPU 1 determines whether or not there is a line head check instruction from the PC through the I / F unit 13.

If there is the line head check instruction and the process proceeds to step S26, the process proceeds to step S26.
The PU unit 1 sends a line head check instruction to the recording material / ejection detecting unit 21 and the recording material / ejection detecting unit 2
1 measures the recording material width, and the result (recording material width) is set in the recording material width storage unit 10.

When the type of the recording material is set in the recording material type storage section 5 in step S24, the process proceeds to step S27. In step S27, the CPU section 1 issues an instruction to measure the recording material width.

On the other hand, if they match, the process proceeds to step S33. In step S33, by the operation of the CPU unit 1,
Based on the recording material type in the recording material type storage unit 5, “0” or “1” indicating the history state of the same recording material type in the recording history storage unit 2 is extracted, and the recording material type and this state are extracted. Recording material table unit 1 based on “0” and “1”

If the result (recording material width) is set in the recording material width storage unit 10, then the process proceeds to step S37. In step S37, it is checked whether or not the recording material width is the largest by the operation of the CPU unit 1. Therefore, if the recording material width is not the maximum, the process proceeds to step S32 to discharge the recording material, and then returns to step S23 to repeat the above steps.

Next, in step S38-3, C
The PU unit 1 sends an ejection failure detection instruction to the recording material / ejection detection unit 21 and inspects the recorded check patterns in order from the right end by the recording material / ejection detection unit 21. The result is sent to the CPU unit 1, and the position of the abnormal part is set in the abnormal position storage unit 22.

It is set in the material table 12. That is, the CPU unit 1
Checks the types of recording materials listed in the recording material table 12 in the following flow.

First, it is checked whether or not the A1 vertical "0" state is recordable. If the width from the current right end position to the abnormal position on the left side is larger than the width of the recording material, recording is possible. In that case, the right end position is left as it is, and the process proceeds to the next A1 vertical "1" state check. If the width from the current right end position to the left abnormal position is smaller than the width of the recording material by such a check, the width of the recording material between both ends of the recording material and the adjacent abnormal position to the left and right of each abnormal position. It is checked in order of the left side and the right side whether or not it can be taken. This check is
It is performed cyclically in order from the abnormal position on the left side of the current right end position. If the recording material width can be obtained by the above check,
If it is to the left of the abnormal position, the abnormal position is set as the right end position. If it is to the right of the abnormal position, a value obtained by subtracting the recording material width from the abnormal position is set as the right end position. On the other hand, if the width of the recording material cannot be obtained, “none” is set for both the right end position and the character position.

Next, similarly, it is checked whether or not the "1" state in the vertical direction of A1 is recordable, and the result is set at the right end position and the character position. Then, from the contents of both the “0” state and the “1” state in the A1 vertical direction, if only one of them can be recorded, the value is applied to the other. Similarly,
The recording material type (paper type) is checked one after another, and the result is set in the recording material table 12 (FIG. 22). When the B4 vertical check is completed, the discharge check is completed.

In step S38-5, the CPU 1 instructs the recording controller 6 to discharge the recording material (paper), discharges the recording material, returns to the main routine of FIGS. 24 and 25, and returns to FIG. Return to step S22. Step S22
Then, the type of the recording material and the right end position at which the recording can be performed while avoiding the abnormality of the line head 7 are displayed on the recording material display section 4. Then, the process proceeds to step S23 (FIG. 24) and waits for the next recording instruction. Repeat the above steps.
