In the facsimile machine 1 according to the present invention,
At the time of facsimile reception or facsimile transmission request, the temperature T of the ink tanks 23C, 23M, 23Y, 23B or its surroundings is measured and detected by the thermistor temperature measuring unit 31, and based on the temperature T, the received image information is detected.

The temperature T is detected directly or in the vicinity of C, 23M, 23Y, and 23B, and the printing operation is controlled based on the temperature T, so that the printing operation optimal for the viscosity of the stored ink can be executed. Thus, the received image information can be printed with high quality.

Hereinafter, specific control of the printing operation will be described.

FIG. 4 is a flowchart showing the first print control operation of the control unit 6. When image information is received by facsimile (FAX) in step a1, the process proceeds to step a2, where the thermistor temperature measuring unit 31 of the temperature detecting unit 14 is used.
To measure the temperature T. The detected temperature T is provided to the control unit 6 by the temperature detection unit 14. In the next step a3, the detected temperature T is compared with a predetermined temperature T1, for example, 15 ° C., and it is determined whether or not T ≦ T1. Step T if T ≦ T1
The process proceeds to step a4, and if T ≦ T1, the process proceeds to step a9. In step a4, the detected temperature T is compared with a predetermined temperature T2 (T2 <T1), for example, 10 ° C., and it is determined whether or not T ≦ T2. When T ≦ T2, the process proceeds to step a5, and when T ≦ T2, the process proceeds to step a7.

In step a5, the received image information is stored and stored in the image storage unit 11, and then the flow advances to step a6 to wait for an instruction to execute a printing operation by pressing the print button 18. When there is an instruction to execute the printing operation, the process proceeds to step a8. In step a7, the received image information is stored in the image storage unit 1.
1 and stored, and the process proceeds to step a8. Step a
In step 8, the heating section 32 heats the sheet to a predetermined temperature T3 (T3> T1), for example, 18 ° C. In a next step a9, a printing operation of the image information is executed.

As described above, according to the first printing operation, T
When the detected temperature T satisfying .ltoreq.T2 is relatively low, the received image information is stored and stored in the image storage unit 11, so that it can be read out at an appropriate time and printed with high quality. When the detected temperature T where T> T1 is relatively high, the received image information is printed immediately. In this case, the received image information is printed with high quality. Further, when T> T2 and T ≦ T1, the received image information is stored and stored in the image storage unit 11 and printed. Therefore, when the print quality is poor, printing can be performed again at an optimal time. As described above, since the optimum printing operation is selectively executed based on the detected temperature T, the received image information can always be printed with high quality.

The image information stored and stored in the image storage unit 11 when the detected temperature T satisfying T ≦ T2 is relatively low is designated by a print button 18 which is a designating means at an optimal time. Can be printed. Similarly, with respect to the image information stored and stored in the image storage unit 11 when T> T2 and T ≦ T1, printing can be designated and printed by the print button 18 as a designating unit at an optimal time. .

On the other hand, when the detected temperature T satisfying T ≦ T1 is relatively low, the heat sheet 3
2, the ink tanks 23C, 23M, 23Y, 23
B or its periphery is heated to T3 higher than T1. Then, the received image information is printed. Therefore, it is possible to print image information with high quality by lowering the ink viscosity. By printing the image information in this manner, the image storage unit 1 of the received image information is printed.
1 is reduced, and overflow of received image information can be prevented. Further, by immediately printing the received image information, the operator can view the printed matter immediately after the reception. The heating by the heating means may be always performed.

FIG. 5 is a flowchart showing the second print control operation of the control unit 6. When image information is received by facsimile (FAX) in step a1, the process proceeds to step a2, where the thermistor temperature measuring unit 31 of the temperature detecting unit 14 is used.
To measure the temperature T. The detected temperature T is provided to the control unit 6 by the temperature detection unit 14. In the next step a11, the detected temperature T is compared with a predetermined temperature T4, for example, 5 ° C., and it is determined whether or not T ≦ T4. If T ≦ T4, step a12
The process proceeds to step a13 if T ≦ T4 is not satisfied. In step a12, the received image information is stored in the image storage unit 11, and then transferred to another facsimile machine. In step a13, a printing operation of the received image information is executed.

As described above, according to the second printing operation, T
When the detected temperature T, which satisfies ≦ T4, is considerably low, the received image information is transferred to another facsimile machine. In this manner, the stay of the received image information in the image storage unit 11 can be reduced, and the overflow of the received image information can be prevented. Note that, for example, the temperature T4 is lower than the temperature T2.

The second printing operation is performed when an image cannot be printed such as when freezing of ink is expected, when the free space of the image storage unit 11 becomes small, and when the storage capacity of the image storage unit 11 is originally reduced. This is effective when there are only a few. The transfer destination facsimile apparatus is, for example, a facsimile apparatus that performs printing by a method other than the inkjet method or a facsimile apparatus having an ambient temperature of room temperature. Such a transfer destination facsimile is registered in the facsimile apparatus 1 in advance. The transfer of image information can be realized using a known technique.

FIG. 6 is a flowchart showing the third print control operation of the control unit 6. When a facsimile (FAX) transmission request for image information is received in step a21, the process proceeds to step a22, where the temperature T is measured by the thermistor temperature measurement unit 31 of the temperature detection unit 14. The detected temperature T is provided to the control unit 6 by the temperature detection unit 14. In the next step a23, the detected temperature T is compared with a predetermined temperature T5, for example, 10 ° C.
It is determined whether or not ≦ T5. When T ≦ T5, the process proceeds to step a24, and when T ≦ T5, the process proceeds to step a26.

At step a24, it is determined whether or not the received image is a monochromatic image. If it is a monochromatic image, the process proceeds to step a26, and if it is not a monochromatic image, the process proceeds to step a25. In step a25, it is determined whether or not the received image is a low-resolution image. If the image is a low-resolution image, the process proceeds to step a26. If the image is not a low-resolution image, the process proceeds to step a28.

In step a26, the facsimile reception of the image is permitted, and the flow advances to the next step a27 to execute the printing operation of the received image information. In step a28,
Reject facsimile reception of images. In this case, a response similar to that of a telephone is made without sending a response signal as a facsimile machine.

As described above, according to the third printing operation, T
When the detected temperature T satisfying .ltoreq.T5 is fairly low and the image to be received is either a monochrome image or a low-resolution image, image reception is allowed. Monochrome or low-resolution images are less affected by image degradation. Only such an image is received, and reception of other images is refused, so that the image can be printed with high quality. Further, in this way, the stay of the received image information in the image storage unit 11 can be reduced to prevent overflow.

Allowing reception only when the received image is a monochrome image or a low-resolution image is as follows:
For example, in the pre-facsimile procedure (Phase B), it is possible to achieve that a color image receiving capability and a fine image receiving capability are not transmitted to the other party's facsimile machine.

For example, the temperature T5 is lower than the temperature T2. The temperature T5 may be the same as or different from the temperature T4.

In the case where the transfer destination facsimile apparatus described in the second printing operation is not registered or the facsimile apparatus does not have the image storage unit 11, the facsimile reception may be refused.

An example in which the control unit 6 selectively performs any one of the above-described first to third print control operations is also included in the scope of the present invention. For example, a program for selecting which print control operation to execute based on information such as the detected temperature T and the free space of the image storage unit 11 is created, and the control unit 6 is configured to operate according to the program. Can be. Further, it is possible to configure so as to select a print control operation to be executed according to an instruction of the operator.

Set. At this time, the display unit 10 may be used.

Further, T ≦ T1, T ≦ T4 or T ≦ T5
The present invention also includes an example in which a warning is generated at the time of (1) and the control unit 6 is configured to selectively execute any one of the first to third print control operations when the warning is generated. Things. Thereby, the received image information is stored and stored in the image storage unit 11 and printed, stored and stored in the image storage unit 11, printed, stored and transferred, and reception of the image information is rejected. Any of the printing operations can be selectively performed. For example, since the function can be freely set by the operator, the convenience of the facsimile machine 1 is improved.

It is also within the scope of the present invention to output data relating to the received image information stored in the image storage unit 11. The output of the relevant data can be performed by the display unit 10 or the printing unit 13, for example. An operator who sees the output related data can grasp what image information is received and stored in the image storage unit 11, and can print desired image information from the information, for example. .
