It could be anything, when there's a hardware malfunction, the scanner just will not allow any action. As it is also an old scanner, any documentation of LED error codes will be long gone, too. It's a shame when well built peripherals die.

When turning on tv. screen will display Bravia image & then go blank. red light flashes SIX times

Power off the television. Wait a few minutes, then power it back on. If this does not correct the issue leave the power on, point your remote control towards the Sony television and hold the down arrow button. While holding the down arrow button press the "Power" button. Release the down arrow button and the Sony TVicon1.png will reset itself to factory settings. Once the television performs a scan on itself your problem should be gone.

Xerox Documate 252, just quit working

The flashing green light has the following meaning:

• Blinking green: indicates the scanner is waking up from power
saving and preparing to scan.
• Steady green: indicates the scanner is ready to scan.

How to Adjust the Power Save Settings for the DocuMate 252
1. Right-click on the One Touch icon and choose Show
Hardware from the pop-up menu.
You can also click the scanner icon at the top of the One Touch
Button Panel.
If the Hardware View of the panel is open you can also right-
click on the DM252 icon.
The Hardware Properties dialog box opens and shows
information about your Xerox DocuMate 252 scanner.
2. Click the Properties button.
Your scanner has a built-in power saving feature that is set to
power down after 15 minutes of idle time. You can change the
time before the scanner powers down, from 1 minute to a
maximum of 3 hours.
3. Click the arrows for the Lamp timeout setting and choose a
time setting.
To return the scanner to its factory settings, click Reset Device.
4. Click OK to save the changes and close the dialog box.

Let me know if this solves the problem and thank you, Binary Bob

Canoscan 9950F won't scan, says scanner locked, but it isn't

I was surprised by the same problem this morning. First time I've had a problem with in years. Checked the lock... it was already unlocked. I solved the problem by unhooking the USB cable from the hub, restarting my Mac (seems to be the key), replugging the cable and restarting the scanner. Worked like a charm. Hope it works for you!

Red light comes when powered

Please try the following to resolve your issue:
1. Unplug the USB cable and the AC adapter from the back of the scanner.
2. Toggle the Transportation lock (located on the bottom of the scanner) back and forth 5 times, ensuring that the lock is all the way in the unlock position.
3. Reconnect the USB cable and the AC adapter cable, and then try to scan.
