92 Troubleshooting and maintaining

The image is completely black or completely white.

The item might not be placed correctly on the scanner glass or in the ADF. Make sure that the item you are trying to scan is placed face down on the glass, or face up in the ADF.

Colors in the scanned image are different from the original item.

Scanners, monitors, printers, and different operating systems interpret color differently. Use the hue and saturation settings in the HP Precisionscan Pro software to adjust the colors.

In the HP Precisionscan Pro software, all of the image scanned when I only wanted part, or vice versa.

The selection area might not be selected correctly. Make sure the selection border is surrounding the area you want in the final scan.

Scanned images are crooked.

The item might have been placed crookedly or shifted when you closed the lid. Straighten the original on the scanner glass and scan again.

I thought I made the image smaller or larger before the final scan in the HP Precisionscan Pro software, but it is still the same size as the original.

You might have zoomed in or out, which does not change the size of the image. Change the output size. See "Resizing (output dimensions)" on page 45.

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 48.

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 45.) Or,

 

if the original was a black and white drawing, use the Black &

 

White Scalable output type for the scanned image. (See

 

"Selecting output type" on page 43.)

￿

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 46.

￿

In the HP Precisionscan Pro software, too much or too little

 

sharpening was applied. Adjust the sharpening. See

 

"Sharpening an image" on page 48.

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 48.

￿

Best Quality Sharpening is selected. Check the setting. See

 

"Setting preferences" on page 68.

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 46 or "Tips for best

 

image quality" on page 67 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.
