HP Scanjet G3010, G4010, G4050 Photo Scanners - Scans are Blank, Totally Black, Have a Distinct Colored Tint over the Entire Scanned Image, or Display One or More Vertical Stripes

Problema:
After scanning an image, the preview screen is blank, completely black; has a yellow, red, pink, or blue/green colored tint over the entire scanned image; or has vertical stripes that are black, white, or multicolored.
Solução
Follow the steps below. Start with the first step and if that does not resolve the issue, go to the next step. You might not need to perform every step.
  1. Re-home the scanning carriage:
    The scanning carriage in the scanner may have lost the home position and needs to be reset.
    1. Shut the computer system off and then disconnect the scanner from the power source. Leave the scanner disconnected from the power source for at least one full minute.
    2. Reconnect the power and then restart the computer system.
    3. When the computer system has fully restarted, try scanning again. If the scanner functions normally, there is no need to continue with the other steps in this document.
  2. Use the correct power supply:
    It is important to use the correct power supply for each model of HP scanner.
    The first type looks like a small black box with a thin electrical cord attached to it. This is referred to as an “AC power module (wall-mount type).”
    The second type looks like a small black box with a thin electrical cord attached to one end. The detachable power cord (supplied with the unit) can be attached to the other end of the black box. This type of power supply is referred to as a “Power module (brick type)” and “AC power cord.”
    Using a universal power supply; using a power supply from another device (such as a printer or different model of scanner), or using a defective power supply can cause the scanner to show a preview scan as completely black.
    If the power supply in use with the HP scanner is the correct power supply for the scanner, go to the next step.
  3. Ensure the issue is not caused by Electro Magnetic Interference (EMI):
    EMI can cause similar image quality issues. Verify that the scanner is not in the direct vicinity of the computer monitor and/or any speakers. If so, relocate the scanner at least three feet away from the monitor and/or speakers and retry the scan.
