Scanner Has Stopped Working Properly - HP Scanjet 7600 Série Guide De L'utilisateur

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.
The carriage on the scanner will move forward and backward approximately 25 mm (1
inch), and the lamp will turn on.
If the carriage does not move and the scanner lamp does not turn on, a problem might
exist with the scanner hardware. See "Product support" on page 23.
