[Correction Level]: | If high-density areas of images are too light in environments with a high temperature or humidity, adjust to the [+] side from the current value. Note that if the value is too large, a density change is likely to occur in low density parts of the image. If the image is too dark or too light in environments with a low temperature or humidity, adjust to the [-] side from the current value. Note that if the value is too small, a density change is likely to occur in high density parts of the image. If the density is different only in the low density parts of an image, adjust to the [+] and [-] sides as necessary. |
[Correction Amount]: | If an adequate image cannot be output by adjusting [Correction Level], adjust the position to start correction. Enter a value, regarding the position 20 mm from the head as 0. |
