mount applications where the imager is mounted upside down.
1IX
Invert around the X axis (flips picture upside down)
1IY

IF- Noise Reduction: Used to reduce the salt and pepper noise.
0IF
No salt and pepper noise reduction (default)
1IF
Salt and pepper noise reduction
Note: You may enable the Salt and Pepper Noise Reduction option if you have
firmware with a base number of 31205122-064 or greater. Refer to the
on page 10-2 for information on determining the
firmware revision in your unit.

0IR
Image as snapped (rightside up) (
default)
1IR
Rotate image 90 degrees to the right
2IR
Rotate image 180 degrees (upside down)
3IR

J - JPEG Image Quality: Sets the desired quality when the JPEG image
format is selected. Higher numbers result in higher quality, but larger files.
Smaller numbers result in greater amounts of lossy compression, faster
transmission times, lower quality, but smaller files.
(Default = 50)
nJ
Image is compressed as much as possible while preserving quality
factor of
n (n = 0 - 100)
0J
worst quality (smallest file)
100J
best quality (largest file)
K - Gamma Correction: Gamma measures the brightness of midtone values
produced by the image. You can brighten or darken an image using gamma
correction. A higher gamma correction yields an overall brighter image. The
lower the setting, the darker the image. A setting of 100 results in no
adjustment to the image. The optimal setting for text images is 50K.
0K
Gamma correction off
(default)
50K
Apply gamma correction for brightening typical document image
nK
Apply gamma correction factor
n (n = 1-255)
