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, verify that the scanner is turned on.
To test the scanner hardware, follow these steps:
1. Disconnect the USB, power, and TMA/ADF cables from the scanner.
2. Reconnect the USB, power, and TMA/ADF cables 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.
