Scanning an Image or Text (HP 7400c, using HP Precision Pro 3.02)
This specific model scanner and software is available to the SLU community 24 hours/7 days in the Madill 222 computer lab. This equipment is also available for faculty
in the Faculty Project Lab at the Center for Teaching and Learning,
62 Park Street.
There are five main steps to the scanning process:
Scanning the document 
- Place your document face down on the scanner glass
- Open the scanner software by clicking
Start > Programs > HP Precision Pro
- Click Start a New Scan if the image has not been scanned
already, or if you reposition the document
Fine-tuning the
selection
- Select the entire scanning area by clicking on the
scanned image.
- Move the mouse to one
of the corners, when you get the double-ended arrow, modify the
border selection around the image as needed to select a particular
area
Select output
type of scan
- True color -{16.7 million colors} - for a very detailed color image.
Large file size when saved
- 256 Color - for a less detailed image in terms of color representation.
Smaller file size
- Grayscale - this is a good setting for a colored image that is going
to be printed on a B/W printer
- B&W - Black & White Image - This would be the appropriate setting
for either scanning a B&W image, or a color image you wish to convert
to B&W
- Editable Text - This setting is for a document of
text that needs to be edited, when one does not want to take the
time to retype the information. It will convert an image of text
into text that can be edited in a text program such as Word, to be editied,
saved, and printed
- This setting will often produce flaws,
and may not interpret the scanned text exactly correct. However,
it will still save a great deal of re-typing time on longer documents
- Text & Image - This setting is for a combination of the above
elements, again either the image, or the text may possibly be distorted
in some way
Scanning destination
- Clicking the Scan To… button will present the
user with different choices of programs to send the scanned image
or text into. Some of these programs are: Microsoft Word, Microsoft
PowerPoint, Microsoft Paint, Adobe Acrobat, and the default e-mail program
as an already attached item to a new message
- Clicking Save
as… will provide the user
with a save menu to choose the file location, and to designate
a type such as .rtf (text), .bmp (bitmap), .jpeg (most common picture
format), etc
- Clicking the Print… button will
send the scan to the selected printer
Adjusting the colors
- Color in an image consists of its hue and the saturation
- Hue refers
to the overall color cast of the image. The software sets the hue
for an image, but you can change it. You might want to change it if
the image has too much of one color, or if you want to create a special
effect
- To change the color hue:
- On the Advanced menu, click Adjust Color
- Change the overall color of the image by doing one of the following
on the color wheel:
- Drag the indicator circle to a new area
- Click the arrow for a color on the outer edge of the wheel
- The result of the change can be seen in the image
- If the
image has too much of one color, move toward the color's
opposite
Resizing (output dimensions)
- You can resize the image before you do the final scan by changing
the output dimensions
- Resizing the scanned image to the actual dimensions
you need before performing the final scan helps ensure the best
image quality
- If you need to resize images to fit in a file, such as word-processing
document, resize them here in the scanning software
- Resizing images
in the other program may cause them to be fuzzy or have jagged
edges
- To resize an image:
- On the Tools menu, click Resize
- The Resize dialog box opens
- Do one of the following:
- If necessary, select a unit of measure in the
Units field. In the Output Dimensions area, type a new value
in the Width or Height field, press Enter
- OR in the Scale field, select a scale percentage
- New values appear in the Scale, Width, and Height fields, but the selection
area and the scanned image on screen remain the same. Resizing only occurs
when you complete the scan.
- If required, click the lock icon.
- This locks
the output dimensions you defined so you can change the selection area
without changing the output dimensions. When you change the selection
border, the software resizes the border proportionally. The output dimensions
remain the same
Changing the resolution
- Resolution determines the amount of data in a scanned image. The
scanning software chooses the optimal resolution based on the output
type. This resolution generally does not need to change
- If you do change the resolution, choose one no higher than the capabilities
of the monitor or printer and one appropriate for the type of scanned
image.
- For example, to print on a 600 dpi printer, choose 600 for
black-and-white bitmap images, but choose only 200 for color or grayscale
images. These resolutions produce optimal quality while keeping file
sizes small
- Selecting higher resolutions for color images increases file size
while not increasing quality. If you double the resolution, the file
size quadruples. Large file sizes can prevent you from doing certain
tasks, such as e-mailing, or can take up too much space on your computer
- To change the resolution:
- On the Tools menu, click Change Resolution
- Select a value from the list OR type a value between 12 and 999,999
in the field and press Enter
- The resolution changes as soon as you
select a value
- To reset the resolution
- On the Tools menu, click Change Resolution
- Click the icon
to the right
Changing image contrast
- The contrast is controlled by the midtone, highlight, and shadow settings
- To adjust image brightness & contrast attributes
- On the Advanced menu, click Adjust Exposure
- Do one of the following:
- Drag the Midtone slider to the right for lighten, and to
the left for darken.rag the Shadow (dark color emphsis)
to the right for more shadow, and left for less shadow.rag the
Highlight (white color emphasis) to the right for more
Highlight, and left for less Highlight
- Type a higher number in the value boxes on the right, press Enter
- Click the Up/Down arrows to the next to the value boxes as
needed
Rotating an image
- You can rotate the image in 90-degree increments clockwise or counterclockwise.
You might need to rotate the image if you placed the bottom of the
item at the top of the scanner glass, or if the item was sideways.
Items such as negatives in their template often scan sideways
- To rotate an image:
- On the Tools menu, click Rotate right/left 90°
- Or, simply click
the directional arrow icon on the toolbar
Mirroring (reversing) an image
- You can mirror, or reverse, an image from side to side on the vertical
axis
- Mirroring an image allows you to see the elements of the image
on the opposite side of their actual position, as if you were holding
it up to a mirror
- Mirroring can be particularly useful for items such
as negatives that might be placed in their template backward
and scanned in reverse
- To mirror (reverse) an image on the Tools menu, click Mirror. Repeat
to return to the original layout
Sharpening an image
Increasing sharpening enhances detail in the image. The HP PrecisionScan
Pro software automatically selects the optimal sharpen level, but you
can change it. You might want to increase sharpening if the image looks
fuzzy. Conversely, you might want to decrease sharpening if the original
item has flaws or marks on it. Increasing sharpening, or increasing it
too much, can accent the flaws and create undesirable patterns.
- To sharpen an image:
- On the Tools menu, click Sharpen
- Select a sharpen level from the
list. The viewer shows the effect of the changes on the image
- To reset the sharpening, click Tools, click Sharpen, click the icon to the right of the value box
Resetting all adjustments
- You can reset images to the optimal (default) values the scanning
software chose for the image
- Optimal values are based on the output type selected
- Resetting removes all adjustments you have made except the output
type, zoom level, or the selection area
- Do one of the following:
- On the Edit menu, click Undo Editing Changes
- On the toolbar, click the circular arrow icon on the toolbar
