User’s Guide7-127
Resolution
The resolution determines the amount of detail you can see in the scanned image. Resolution is the clarity of the 
image measured in dots-per-inch (dpi).
Move the slider left or right to change the resolution for the scanned image. The higher the resolution, the clearer 
the image. However, high resolution scans also produce larger file sizes. The available range displayed in the 
slider area are within the minimum and maximum range supported by your scanner. The resolution slider will 
always display the correct range for the current scanner.
Choosing resolution values
Typically, when making copies of black and white documents, 100–150 dpi will create an image of similar quality 
to the original. When making copies of color documents or photographs, 150–200 dpi will create an image of 
similar quality to the original.
Higher resolution settings are generally used for creating an image that can be enlarged without losing image 
quality, but take longer to scan.
Some resolution settings for typically scanned items are:
•Te x t  d o c u m e n t letters, forms, or other typed black and white documents – 100 dpi to 150 dpi
•Te x t  d o c u m e n t letters or forms with hand printed text – 150 dpi
•Te x t  d o c u m e n t  ( f o r  O C R )  forms, letters, memos, or spreadsheets – 300 dpi
•Business cards or other items with small print – 300 dpi
•Color page with graphics or color photographs – 150 dpi
•Color photographs of poor quality for image enhancement – 300 dpi
•Color photographs for printing – 200 dpi
•Color photographs for email – 100 to 150 dpi
•Magazine page with graphics, line art, or color photographs – 200 dpi
Document Size
Standard document sizes
Click the drop down menu and select a pre-defined document size from the list. The available document sizes are 
within the scanner's range of minimum and maximum item size.

User’s Guide 7-128 Custom document sizes
Select the measurement units you want to use from the Units list.
If the Document size list does not include the document size for your scanning batch, click in one of the fields 
below the document size list. Input the width of the document in the first field, then input the length in the 
second field. You can only specify values within the scanner's minimum and maximum supported item size. 
Please refer to the maintenance section of the scanner user's guide for this information.
Please refer to Long Document if your scanner supports page lengths greater than 17 inches and you want to 
scan long pages.
Long Document
Select Long document to enable support of paper sizes up to the scanner maximum. After you select this option 
make sure you input the page length for your document in the custom input field, located below the Document 
size selection list. When the value in the custom field is less than the actual document length, the scanned page 
will be split across multiple images. For example, if you are scanning a document that is 22 inches long, and the 
field is set to 11 inches, the final scan will be split across 2 images. 
Note: the document you want split across multiple images does not have to be unusually long. You can scan any 
item within the scanner’s supported paper sizes and the images will be split based on the length in the custom 
document size field.
Note that some of the options in the scanner interface cannot be used when the page length will be greater than 
17 inches. When you select this option, incompatible options will either be automatically disabled or the setting 
will simply be discarded while scanning. 
Manual Feed
Select this option to enable a delay from when the last page is scanned and when the scanner stops the scan job. 
This allows you to scan one page at a time without having to click Scan for each page you put in the scanner. 
To scan with manual feed mode:
1. Select Manual feed in the scanner’s interface.
2. In the Timeout field, input the amount of time you want the scanner to wait from when the last page is 
scanned and when the scanner stops scanning.
3. Place a document in the scanner.
4. Click Scan.
5. The scanning progress dialogue on-screen will display a countdown indicating how much time you have to 
place the next document in the scanner.

let the timer run out.
Straighten Image
Select this option to let the scanner automatically determine if a page is skewed, then straighten its image. This 
option is only available if the scanner supports this feature.
If you are scanning using an automatic document feeder, and the page is fed through at too great of an angle, 
the image may not straighten correctly. In that case, re-scan the page making sure the paper guides are adjusted 
to the width of the pages in the input tray so that the pages are pulled straight through the scanner.
Rotate Image
Select an option in this list to have the final image rotated when scanning is complete.
Flip Back Side
Select this option if you are scanning duplex pages that are calendar style orientation. This option will rotate the 
back side image 180 degrees from the front side.  When scanning in duplex mode without this option selected, 
the back side image of calendar orientation pages will appear upside down in the final scan. This option does not 
automatically determine book page orientation versus calendar page orientation.  If you have this option 
selected when scanning book orientation pages, the image for the back side of the page will appear upside down 
in the final scan.  If you are scanning a batch of documents that contain both types of orientation, we 
recommend that you select Automatic in the Rotate image list. 
This option is available only if the current scanner supports duplex scanning and the Duplex option is selected in 
the scanning interface.
Merge Two Sides
When scanning in duplex mode, you can enable this option to have both sides of a scanned item appear on one 
page in the final image file.  The options in the list allow you to select where you want the front side image to 
appear in relation to the back side image in the final file.  
						

							Scanning from TWAIN and WIA
Xerox
® DocuMate® 4790
User’s Guide 7-130 The following image shows a cheque scanned in duplex mode without Merge two sides enabled, and the same 
cheque scanned with Merge two sides enabled.  When Merge two sides is not enabled, side 1 and side 2 of the 
cheque are saved in two separate files (IMG_0001 and IMG_0002 respectively).  With Merge two sides enabled, 
both sides of the cheque are in a single file (IMG_0003).  If you are scanning a stack of items using a multipage 
file format, such as a PDF file, then each page in the final file will have both the front and back images of the 
scanned items.
Height threshold
Input the maximum height of images to be merged. The sides will not be merged if the height of either the front 
or rear image exceeds this value. For example, if you are scanning a batch of mixed documents such as cheques 
and statements, you may want both sides of the cheques merged into one image but not the statements.  The 
Height threshold needs to be lower than the length of the documents you do not want merged into a single file.
Select one of the options in the Merge two sides list to enable this field. Note that you will also need to enable 
Long document if you want to have the maximum height threshold be longer than 17.
Advanced Panel Options
The options in this panel may also appear in the Main panel, but with additional settings for you to fine-tune the 
feature you've selected. Select the Advanced source configuration mode to show this panel.
Skip Blank Originals
Select this option to have the scanner detect if a blank page has been fed through the scanner, and remove it 
from the final file. Typically you might use this option when scanning a stack of two-sided pages which have a 
number of blank sides. 
						

							Scanning from TWAIN and WIA
Xerox
® DocuMate® 4790
User’s Guide7-131 •Blank threshold—you can use the Threshold slider to fine tune the sensitivity of the blank image detection. 
The results will depend on the scan settings and the types of documents being scanned.  In general leave the 
threshold level at the default setting if you are scanning good-quality documents printed on standard 20lb 
printer paper.  Try lowering the sensitivity level if your documents contain light colored text or drawings so 
those pages are not detected as blank.  Raise the sensitivity level if you are scanning double-sided light-
weight paper where images from the opposite side of the page may appear in the image of the blank side. 
Clean Up Edges
Select this option to remove any thin lines from around the edges of the final scan.  This option will fill the 
margins of the image with the detected edge color.  When you select this option, the Width input field will 
automatically enable for you to input the size of the area you want to have filled with the background color.  You 
can specify a fill size between approximately 0.04 to 0.39 inches (1 mm to 10 mm).
Automatic Image Cropping
Depending on the scanner model and installed software, there may be more than one auto cropping option in 
the interface.
•Crop to original—select this option to let the scanner automatically determine the size of the item being 
scanned. This option is only available if the scanner supports this feature. This option may occasionally be 
grayed out as not all scanning applications support this feature.
Always properly adjust the paper guides to the width of the paper in the input tray so that the pages feed 
into the scanner as straight as possible. Skewed pages may not crop properly. 
•Crop to length—this option tells the scanner to crop the final image to the bottom of the page being 
scanned. This option is only available if the scanner supports this feature. This option may occasionally be 
grayed out as not all scanning applications support this feature.
Compression Options
There are two types of image compression functions used during scanning.  The input compression option is 
compressing the image when transferring it from the scanner to the TWAIN driver on the computer.  The output 
compression option is the TWAIN driver compressing the image before it sends the image to the scanning 
application.  In the scanning interface the input compression option is Compress transfers and the output option 
is Compression.
Compress transfers
Select this option to have the scanner compress the image in Gray and Color scans.  This reduces the file size and 
allows for faster image transfer from the scanner to the computer.  Once the compressed image is on the 
computer, scanner’s driver will then uncompress the image, and perform any image processing functions that 
have been selected in the scanning interface.  The uncompressed image is then transferred to the scanning 
application.  With Compress transfers, a scanning application such as Nuance PDF Converter, will receive the 
uncompressed image and save the image in whatever file format it uses. You can use the Quality slider to adjust 
the level of compression you want to use.
When the Quality option is set to High quality, there is very little visual difference between a compressed scan 
and an uncompressed scan.  When the quality option is set to High compression, there may be a greater visual 
difference between compressed and uncompressed scans.

User’s Guide 7-132 Quality
You can fine tune the compression level by adjusting the quality slider between high compression and high 
quality.  When the quality level is set to high compression, the scanner will scan and transfer images faster than 
high quality, but the image quality of the output scan will be lower.
Subsampling
The subsampling options allow you to select the encoding ratio between color information and luminosity. 
Subsampling works by lowering the resolution of the RGB colors found in an image without affecting 
luminescence of the image. This compresses the image to create smaller file sizes but it can sometimes result in 
loss of image quality.  Depending on the type of image being scanned, subsampling encoding may not have a 
noticeable affect in the final image file. You should try test scans using the different levels of subsampling to 
make sure you are happy with the image quality.
•4:4:4—no subsampling and the ratio between color and luminosity remains unchanged.
•4:2:2—mid-level ratio between color and luminosity.
•4:1:1—highest ratio difference between color and luminosity, which results in saving the smallest file size.
Compression
This option is specific compression for file and memory transfers to an application.  It is only available if the 
application you are using can accept a compressed image file.  For instance, if your scanning application is set to 
receive JPEG compressed images, then the Compression field will display JPEG.  Otherwise, the status for 
Compression will always be disabled and display Uncompressed because the scanning application you are using 
is requesting an uncompressed image.
The Compress transfers option described herein compresses the image for faster transfer from the scanner to the 
computer.  The driver uncompresses the image and transfers the uncompressed image to the scanning 
application.  The Compression option will often be disabled as most applications do not support receiving a 
compressed image file from the scanner driver.
When this option is available, it is an advanced user and application option and should not be adjusted if you are 
not familiar with the technology. However, if you are certain that you are using an application that can receive a 
compressed image, and you want to be able to change the image compression type, you will need to enable user 
adjustable compression in the scanning interface. Please refer to the Driver Settings section for instructions.
Please note that if you adjust this setting, and the application cannot actually accept the option you change, the 
scanning interface and the application may crash. It is highly recommended that you leave the default options 
and let the application set any image compression.
