Using Photoshop to change the text on the scanned document to the required text is:

1, open the picture, use the "eyedropper tool" to absorb the background color of the file and set it as "foreground color";

2. Use the Brush Tool to set the "Soft Edge Circle" brush and smear the text to be removed;

3. You can also use the "Imitation Stamp Tool" to set the background of the document without text as the "source" point, and then move it to the text to be removed to cover the text;

4. Use the same font and color as the original file, type the required text, and use ctrl+t to adjust the size and position;

5. "Filter-blur-Gaussian blur";

6. According to the overall effect of the picture, appropriately adjust the text "transparency" and so on.
