Scanner Error Message

I just loaded this all in one printer to my 2000 windows pro computer, today, and when I first loaded it my scanner worked, just fine. Now when I go to use it gives me an error message saying "Cannot Connect To PC", and when I try to access it from my pc it says that it cannot detect this and to make sure it's connected properly. Any advice on this so that I can get my scanner back?

Re: Scanner Error Message


I understand that you are unable to scan from computer as well as from the printer front panel.

The issue that you are experiencing might be with the USB drivers unable to detect the printer.

However, please follow the below given instructions to resolve the issue.

Check for the communication between the computer and the printer by following the below given instructions:

To isolate the issue I suggest you to try scanning from Imaging for Windows which will scan from the all-in-one product using TWAIN software instead of the HP software.

1.Verify that the all-in-one product power is turned on and the printer cable is properly connected.

2.Click Start then Click Programs then Click Accessories then Click Imaging.

3.From the Imaging application, click File, and then click Select Device.

4.Select the HP all-in-one device from the TWAIN source list.

5.Click File, and then Acquire Image.

If you are unable to scan from the above steps, then confirms that the issue is with communication.

Refresh the USB composite drives to resolve the issue.

1. Right-click My Computer (in Windows XP, click Start first), and then click Properties.
2. Select the Hardware tab and then click Device Manager.
3. Click the Plus (+) sign next to Universal Serial Bus Controllers.
4. Click the USB Composite Device entry to highlight it, and then click Action and then click Uninstall. If a screen appears to confirm the deletion, confirm the deletion.
5. Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).
6. A New Hardware found screen may appear, click Next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.

Then try scanning, even if the issue still persists uninstall and reinstall the USB drivers:

1. Save and close all programs that are currently running.
2. Click Start, select Shut Down, and choose Restart the computer.
3. Press the F8 function key, this will display the Windows Startup menu.
4. Select Safe mode.
5. After Windows loads in Safe mode, right-click the My Computer icon and select Properties.
6. Select the Hardware tab and click the Device Manager button.
7. In the Device Manager Window, double-click the Universal Serial Bus controllers.
8. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
9. Click OK to confirm the removal of the device.

NOTE: Repeat steps 8 and 9 until all the devices under Universal Serial Bus Controller are removed.

The USB port is now uninstalled.

Now, restart the system. The system automatically detects and reinstalls the USB port.

Then try scanning this should resolve the issue.

If you are unable to scan from software, try running the scan diagnostic utility from the below weblink:

Here is the web link to download scan diagnostic utility:



Just copy and paste the entire link into the Internet browser's address bar and press enter.

Even if the issue still persists uninstall the complete All-in- one software and reinstall it.

This should resolve the issue.

The scanner has quit working. Error message says printer cannot connect. Printing works find from computer. Copying too.

Switch off the scanner and disconnect the usb cable then restart your computer.

When the computer has booted up, reconnect the scanner usb. Try the scanner.

If the problem persists try re-downloading and installing the scanner software

Won't run scanner error message "you need to install or run HP software for this feature" Installed with CD still no fix

Cherokee, You must first disconnect the device. Then uninstall the drivers. Reboot the computer. Reinstall the drivers. Reconnect the device and allow Windows sufficient time to auto detect and load up the drivers. Then only will the scanner work properly.

Trouble with Scanner

Hi Elizabeth,
Different post, same message :)
This is a common complaint.. Are you running Vista, by any chance? The all in one solution software you used in XP doesn't work fully with Vista.

But you can still scan and copy by using Windows Photo Gallery.

1. Click on files tab at the top in Window Photo Gallery.
2. Click on import from camera or scanner.
3. Highlight your scanner icon (ie HP Pro L7650) then click import.
4. New scan window will popup, now you can preview or scan using this basic looking Vista utility.

Hope that helps.

All in One Scanner/Printer problems

Go to this link and type "cannot communicate with scanner" in the search box. Click Search. Then select the "ERROR: Cannot communicate with scanner" link. You will see several things to try to correct your problem. Usually, this error shows up if there is another USB device connected which prevents the computer from "seeing" the scanner, even though it can print without problem. So do try to disconnect any other USB device (except mouse or keyboard) and reboot the system.

Scanner not working

Samsung can be cheeky with support i have found and not as helpful with tech help. Instead of going off in tiny circles with unlocking etc, i would go for the quick fix and suggest your scanner may not have installed properly when you installed it. As you have installed the drivers again with no luck i would even suggest goint to samsung web site and downloading new updated drivers for your printer to eliminate corrupt drivers. Does you pc register the scanner being there? Go to control panel, hardware/ printers, find your printer and check all the drivers and whether scanner is actually present on the pc here.
