Adjusting the settings and buttons on your scanner Most user guides give
you detailed, illustrated instructions as to how to modify resolution settings, configure
buttons, adjust the color, and perform other tasks to refine your images.
How to scan text and transparencies The attachments and software for scanning
text and transparencies differ from scanner to scanner. The user guide is the best
place to find illustrated step-by-step instructions.
Saving scanned images The user guide tells you which file formats and software
applications are available for saving your files, and how to use them.
When the Buttons Won’t Do Anything
External buttons are the latest rage for scanner interfaces. They’re efficient, convenient,
and real time-savers—when they work.
If you have the disappointing experience of pushing promising-looking buttons
that don’t produce any results, you’re not alone. If you have a newer operating
system—such as Windows ME—you might have to download a special driver or
patch from the Web. (The scanner was probably designed and packaged before the
manufacturer had time to update the scanner software to be compatible with the new
operating system.)
For nonfunctioning buttons, your first stop should be the manufacturer’s website to
check for drivers and updates. Hewlett-Packard, for example, provides a software
patch that is required, as of the writing of this book, to make the buttons on its
scanners operate under a Windows ME operating system.
To find a link to a patch, like the one shown in Figure 7-3, go to the manufacturer’s
website and look for a link labeled “drivers” or “updates.” If you don’t see a specific
link on the home page, try looking for it on the technical support pages, or using any
available Search feature provided on the website.
How to Interpret a Flashing Lamp
Some models of scanners signal for help by flashing the lamps under the glass. A
logical interpretation of this would seem to be that the lamp itself is malfunctioning,
but this is actually seldom the case.

Finding drivers and software updates on the manufacturer’s website
Some, but not all, of the causes for a flashing scanner lamp include the following:
A locked scanner Make sure that you’ve unlocked the carriage lock on your
scanner. Chapter 4 tells you how to locate the lock and make sure it’s been properly
released. (The locking device is designed to protect the delicate sensors on the
scanning device in transit.)
A stuck carriage The sensor devices that capture image data are attached to a
moving carriage within your scanner. Sometimes the carriage is stopped, and
needs to be reset. To do this, simply unplug it from the power source to reinitialize
the scanner motion settings.
Damaged or defective sensors Occasionally the delicate sensors on a scanner
carriage are damaged in transit. When this is determined to be the cause of the
flashing lamp, your only recourse is to exchange it for an undamaged model.

When Your Computer Doesn’t Recognize a
Connection to Your Scanner
It might sound obvious, but loose cable connections are often the culprit for this
error message. Even if you think you’ve checked all the connections, check again.
Remember, your scanner needs a connection both to your computer and to its own
separate electrical power source. In other words, be sure to check both the cable that
leads to your computer and the cord that plugs into the wall.
If your cabling appears to be properly connected, try the following troubleshooting
procedures in this section. A logical approach is to attempt them in the order listed here.
Restarting or rebooting your computer allows it to update its settings, and recognize
new drivers and hardware such as a scanner. Use the Shutdown menu option, rather than
Restart. Before you restart your computer, unplug the electrical connect to the scanner
for a full 60 seconds. After you plug your scanner back in, restart your computer. This
process should allow your computer to recognize your new scanner. If not, read on.
Look for a Conflicting Software Driver
Did you have another scanner installed before the one you’re presently attempting to use?
If so, the problem might be a conflicting software driver left over from the old scanner.
Basic Uninstallation Procedure for Old Drivers
Your first line of defense should be to properly uninstall the driver for the old scanner.
Follow these steps to do so:
1. From the Start menu on your Windows taskbar, select Settings, then Control
Panel. The Control Panel dialog box shown in Figure 7-4 appears.
2. Locate the Add/Remove Programs icon in the Control Panel dialog box and
double-click it.
3. The Add/Remove Programs Properties dialog box, listing the software
programs on your computer appears, as shown in Figure 7-5.
4. Locate the driver for the scanner that you no longer want to use and click the
Add/Remove button. A message might appear telling you to restart your
computer so the process can be completed.
5. After restarting your computer, check to see if your computer properly
recognizes the new scanner.

Drivers that Don’t Respond to the Standard Uninstallation
Procedure
If after following the uninstall procedure above, your computer still gives you a
message that it can’t find the new scanner, you might have a stubborn driver that
doesn’t know when its welcome is up. You might have to delete the scanner from your
computer’s list of registered devices in the System Properties dialog box.
To look for the offending driver, follow these steps:
1. Right-click the My Computer icon on your Windows desktop and select
Properties from the pop-up menu. The System Properties dialog box appears,
as shown in Figure 7-6.

Look for a lingering driver using the System Properties dialog box.
2. Click the Device Manager tab and scroll through the dialog box to locate the
Imaging Device icon.
3. Click the plus sign next to the Imaging Device icon to display a list of scanner
drivers currently on your system. There should be only one. If more than one
driver appears, delete the icon for the old scanner driver you’re no longer
using.
