Abstract

PROBLEM TO BE SOLVED: To adjust color deviation in a picture input device. SOLUTION: When a color deviation request is issued, a picture for color deviation correction is displayed on a display device of an operation part 108. When a color deviation correction value and a correction request are issued from the operation part 108, a scanner unit 103 receives the color deviation correction value and the color deviation correction request from a controller 104 to confirm the entire status of a picture input device; and if the picture input device 101 is in such state that color deviation correction is possible, the scanner unit 103 writes and preserves the received color deviation correction value in an NVRAM of the scanner unit 103. The scanner unit 103 copies the color deviation correction set value stored in the NVRAM to an address of data on a prescribed RAM. Thus, the set color deviation correction value is validated.

If it is, the process proceeds to step S802. The processing in the case where the image input apparatus 101 cannot set the document size system is not directly related to the present invention, and therefore the description is omitted.

In step S802, the CPU 409 of the scanner unit 103 writes and stores the document size system setting value received in step S801 in the NVRAM 408 of the scanner unit 103. Step S
At 803, the CPU 409 of the scanner unit 103
In step S802, the document size system value stored in the NVRAM 408 is copied to the address of the data on the RAM 406 which is read as the document size system setting when the scanner unit 103 performs the normal scan. As a result, the set document size system setting value becomes valid. Then, in step S804, the CPU 409 of the scanner unit 103 notifies the CPU 502 of the control device 104 via the connector 411 that the document size system setting has been completed.

In step S703, the scanner unit 1
The CPU 502 of the control device 104 notified of the completion of the document size system setting from 03 notifies the operation unit 108 of the completion of the process. The operation unit 108 switches the screen display from the document size system setting screen to the normal screen and ends the processing.

Here, when the document feeding unit 102 becomes jammed during the normal operation, the image input apparatus 101 writes the number of times and the writing of the location where the jam has occurred in a predetermined address of the NVRAM 408 as needed. It is assumed that it is done.

FIG. 9 shows an example of a processing procedure of the control device 104 and the operation unit 108, and FIG. 10 is a flowchart showing an example of a processing procedure of the image input device 101. When acquiring the jam history of the image input apparatus 101, first, the user or serviceman confirms the display of the jam history acquisition screen on the operation unit 108 in step S901, and then, in step S902, the jam history acquisition screen is displayed. Make a request. The operation unit 108 that has received the jam history acquisition request displays a jam history acquisition request screen on a display device equipped with the operation unit 108,
A request for jam history acquisition from a user or a service person is accepted. The operation unit 108 communicates with the CPU 502 of the control device 104 via the operation unit I / F 513, and issues a jam history request to the CPU 502. Then, the CPU 502 of the control device 104 that has received the jam history acquisition request
Issues a jam history acquisition request to the CPU 409 of the scanner unit 103 via the connector 515.

In step S1001, when the CPU 409 of the scanner unit 103 receives the jam history acquisition request from the CPU 502, the CPU 409 checks the overall status of the image input apparatus 101, and is ready to transmit the jam history. If there is, the process proceeds to step S1002. The processing when the image input apparatus 101 is not in a state in which the jam history can be transmitted is not directly related to the present invention, and thus the description is omitted. In step S1003, the CPU 409 of the scanner unit 103 executes step S901.
In accordance with the jam history acquisition request received in step (1), a process of reading jam history information of the image input apparatus 101 from the NVMM 408 of the scanner unit 103 is executed.

In step S903, the scanner unit 1
03 at step S1002
The jam history information read from 408 is stored in step S1.
001 is transmitted to the control device 104 via the connector 411 as a response to the jam history acquisition request received.

In step S903, the scanner unit 1
03, the CPU 502 of the control device 104 notified of the jam history information as a jam history response.
08, the jam history information is transmitted. The operation unit 108 displays the jam history information on the display unit, and ends the processing.

As a result of the completion of such processing, the jam history information of the image input device 101 is not lost even when the control device 104 is replaced with another control device, and the jam history information is continuously recorded. The information can be stored in a nonvolatile storage device provided.

As described above, according to the present invention,
With the above configuration, the adjustment of the image input device, the setting of the specifications, and the confirmation of the use status do not require a control device with a uniquely determined combination. It is possible to adjust the image input device using the jig.
