HP Scanjet Enterprise 7500 Flatbed Scanner - Manual (Page 48)

Scan files are too large
If the saved scan files are very large, try the following:
● Verify the scan resolution setting:
◦ 200 dpi is sufficient for storing documents as images.
◦ For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create
editable text.
◦ For Asian fonts and small fonts, 400 dpi is the recommended resolution.
Scanning at a higher resolution than necessary creates a larger file with no additional benefit.
● Color scans create larger files than do black and white scans.
● If you are scanning a large number of pages at one time, consider scanning fewer pages at a
time to create more, smaller files.
● Use the Kofax Virtual ReScan Software which shipped with your scanner to process the
scanned data. Such software cleans up the image and compresses the data, which can result in
a smaller file.
Scanner buttons are not working correctly
After each step, press a button to see if it is working correctly. If the problem persists, proceed with
the next step.
1. A cable might be loose. Ensure that the USB cable and the power supply are securely
connected.
2. The HP Scanner Tools Utility might have been used to disable the buttons. If so, use the HP
Scanner Tools Utility to re-enable the buttons.
3. Turn off the scanner, wait 30 seconds, and then turn the scanner back on.
4. Restart your computer.
5. If the problem persists, the buttons might be disabled outside of the HP Scanner Tools Utility.
Try the following procedure:
a. Open Control Panel, select Scanners and Cameras (in Windows 7, select Hardware and
Sound, and then select Devices and Printers), and then select your scanner model from
the list.
b. Display the scanner properties:
● Windows XP and Vista: Right-click your scanner model, and then click Properties.
● Windows 7: Click Scan Properties, and then click the Events tab.
c. Examine the buttons setting for your scanner, and ensure that the Take No Action option
is not selected.
6. If the problem still persists, there may be a problem with the front panel. Contact HP Support at
