Red light comes when powered

Some seconds after I put the power plug into the outlet the flashing green light turned to a flashing red color.

Of course, after I selected Document in the Smart Panel, I received an error message. It indicated that the scanner connection was having a problem. I connected and reconnected all the wires.

In addition, I uninstalled and reinstalled the software, including the driver.
As well, I tried connecting the scanner to another of my computers, and, yet, I continued to see the flashing red light and the same problems indicated above.

Is there anything else I can do. Thank you in advance.
