An original photo was fuzzy, and the scanned image looks even

worse.

The sharpening level needs to be increased. In the
HP PrecisionScan Pro software, adjust the sharpening. See

"Sharpening an image" on page 38

.

Scanned images are grainy, jagged, or fuzzy.

You resized the image in a program other than the
HP PrecisionScan Pro software. Resize the image in the
HP PrecisionScan Pro software before you send it to the other
program. (See

"Resizing (output dimensions)" on page 35

.)

In the HP PrecisionScan Pro software, the resolution is set too
low. Set the resolution to a higher number, or return to the
default setting. See

"Changing resolution" on page 36

.

In the HP PrecisionScan Pro software, too much or too little
sharpening was applied. Adjust the sharpening. See

"Sharpening an image" on page 38

.

An original photo had marks, flaws, or scratches, and the scanned

image looks even worse in the HP PrecisionScan Pro software.

You sharpened the image manually. Return to the default
setting. See

"Sharpening an image" on page 38

.

Best Quality Sharpening is selected. Check the setting. See

"Setting preferences" on page 60

.

I set the image to a higher resolution in the HP PrecisionScan Pro

software, but the output quality is no better.

Setting the resolution to a higher number does not necessarily
improve quality. The software sets the resolution automatically
based on the type of item you scanned. Keep or return to the
default. See

"Changing resolution" on page 36

or

"Tips for best

image quality" on page 59

for guidelines.

If you sent the image to another program, the program might not
support the resolution you set in the HP PrecisionScan Pro
software. Determine the setting the program uses and set the
resolution in the HP PrecisionScan Pro software to that
resolution.

Images scanned from the HP PrecisionScan Pro software are larger

than the original when viewed or printed from another program.

The other program did not accept the image size information. Scan
the image at a lower resolution. When you scan at a resolution the
program accepts, it will display or print the image at the correct
size.

The image is too big or too small.

In the HP PrecisionScan Pro software, set the physical width and
height of the image in the Resize dialog box. See

"Resizing (output

dimensions)" on page 35

.

When I try to scan to the Web from the HP PrecisionScan Pro

software, the image is too large or does not look good on screen.

Scan settings for this image might be set incorrectly. See

"Tips for

best image quality" on page 59
