Scanning from Photoshop it send me directly to the troubleshooting message. I've detected that my scanner is not starting up, I mean, the light is not on and it does not even make the typical noise when is turned on (completely frozen!!) It is probably the 1st or 2nd time I've used it since new (8 months ago) but is refurbished from Epson website. Any advice or how to fixed? It was never beaten or anything. thanks

If you upgraded your operating system from Windows 8 to Windows 10 and are experiencing issues with your HP 4850 scanner, specifically receiving a "no WIA device is located" message, here are a few steps you can try to resolve the problem:
1. Check Scanner Compatibility: Ensure that the HP 4850 scanner is compatible with Windows 10. Visit the official HP website and search for the scanner model to find compatibility information and any available drivers or software updates specifically designed for Windows 10.
2. Update Drivers: Download and install the latest drivers for the HP 4850 scanner compatible with Windows 10 from the HP website. Make sure to select the correct drivers for your specific scanner model and the version of Windows 10 you are using.
3. Uninstall and Reinstall Software: Completely uninstall the existing HP scanning software from your computer. Go to the Control Panel, locate the scanner software, and uninstall it. Afterward, restart your computer and reinstall the latest version of the software provided by HP for Windows 10.
4. Run Hardware Troubleshooter: Windows 10 has a built-in hardware troubleshooter that can automatically detect and fix common issues. Open the Windows Settings, go to "Update & Security," select "Troubleshoot," and then choose "Hardware and Devices." Follow the on-screen instructions to run the troubleshooter and see if it resolves the problem.
5. Check WIA Service: Verify that the Windows Image Acquisition (WIA) service is running on your computer. Press Win + R on your keyboard, type "services.msc," and press Enter. In the Services window, locate the "Windows Image Acquisition (WIA)" service, right-click on it, select "Properties," set the startup type to "Automatic," and click "Start" to initiate the service if it's not already running.
6. Try Compatibility Mode: Right-click on the scanner software executable file or shortcut, select "Properties," go to the "Compatibility" tab, and check the option to run the program in compatibility mode. Choose the previous Windows version (Windows 8) and apply the settings. Then, try running the software again and check if the scanner is recognized.
If none of these steps resolve the issue, it's recommended to contact HP's customer support or visit their website for further assistance. They will have specific knowledge and resources to address any compatibility or functionality problems with your HP 4850 scanner on Windows 10.

Install another scanning software, if you have photoshop or any imaging software, you can use the scanner by going to the menu, then choose File, Import, TWAIN, Acquire and the scanner control will appear.

Or just go to My Computer and double click the scanner icon (in XP) to start the scanning assistant.

Use the Adobe Photoshop for scanning.
Start the Adobe Photoshop Then go to file menu then Import from Scanner.
That its. One more HP also gives a default application for scanning. Use your driver cd & install that application.

Hi there, you are very near in the solution. Just today i solve the same problem manually. When the system ask this message "where I want the image saved " 1st select the path -- My computer/C:/program file/HP scan jet/ select here the Scanner Icon and press Ok. I mean just follow the location of installation file of your scanner. After that scan the image or else , you will get the success. Thanks & waiting for your success feedback.

Don't reinstall Photoshop any more, that's not necessary. Just leave PS alone.
Have you done anything, like upgraded the operating system?
Try a couple of things. We'll start with the easiest.
Try scanning directly from the "Preview" application - this works really well.
Open the application "Preview"
Go to the File menu, and then "Import from Scanner" - hopefully your scanner shows up ...
This is a great way to scan.
If your printer/scanner does not show up when you do this, you will need to (sorry to say) re-install the software for the printer. But you said you already did that!
I'm going to suggest, if you haven't already, to go to hp.com and find your printer and download the package of software for it and reinstall that way - they periodically update the software. HP printers are a bit fussy about this, so reinstalling the "latest" HP software is definitely worth trying.
Hope that helps!

Photoshop is not an "advanced" scanning program. To get some "production" and value out of this expensive scanner you need a professional scanning program which also may control the settings of the scanner. Use PixEdit which utilizes the built-in jpeg compression in the scanner. Did a test scanning 10 pages A4 duplex fullcolor. Adobe Acrobat Pro used 4 minutes. PixEdit used 20 seconds. Guess Photoshop (in your version) would also scan uncompressed and not use this good scanner optimal.

I had the same problem when upgrading to mac os x. I was trying to scan directly from Photoshop but got the calibration message. I tried the two solutions given at the Canon website but they didn't work. I ended up downloading the Toolbox application to scan directly from there but the same message appeared. After installing the Toolbox application I unistalled the driver (11250) and reinstalled it. I opened Photoshop and tried scanning and the calibration window appeared only this time it didn't stop to give me the "Flim Adapter" warning. I must point that the scanner lid was open when this happend but I'm not sure that had anything to do with it.

So apparently it works if you have the Toolbox installed prior to installing the driver. The driver, Toolbox application and unistall driver can be found at Canon's website. Hope this helps.

Ciao!
