Scanner initialization or hardware problems
This section contains solutions for initialization and hardware problems.
Reset the scanner
If you receive an error message similar to “Scanner initialization failed” or “Scanner
not found” when trying to use the scanner, use the following procedure:
1 Close the HP Image Zone software, if it is open.
2 Disconnect the cable that connects the scanner to the computer.
3 Turn the scanner off by disconnecting the power cable.
4 Turn the computer off, wait 60 seconds, and then turn the computer on again.
5 Turn the scanner on by reconnecting the power cable.
6 Reconnect the cable that connects the computer and the scanner (use a different
USB port on the computer if possible).
● A “00” in the LCD on the front panel of the scanner indicates that a USB
connection error has occurred. Check that the USB cable is securely connected
between the scanner and the computer.
● Make sure that the USB cable is connected to the back of the scanner correctly.
The USB symbol on the end of the cable (the connector) should be facing up.
When connected correctly, the USB connector will feel slightly loose. When
connected incorrectly, the USB plug will feel overly tight.
● Try connecting the USB cable to a different USB port on your computer.
Test the scanner hardware
If you think that the scanner has a hardware problem, verify that the cables are firmly
connected to the scanner, the computer, and the power source. If the cables are
correctly connected, test the scanner by using the following procedure:
1 Disconnect the USB cable and power cable from the scanner.
2 Reconnect the USB cable and power cable to the scanner.
