Epson v500 scanner says "No scanner selected" message with Mac Desk OS X

Here are some troubleshooting steps you can try for your Epson V500 Photo scanner: Check the connections: Ensure that your scanner is properly connected to your computer and turned on. Check the cables and ports for any damage or loose connections. Restart your computer: Sometimes, restarting your computer can fix communication issues between your scanner and computer. Reinstall the scanner software: Try uninstalling and reinstalling the scanner software on your computer. You can download the latest software from the Epson website. Check for updates: Make sure that your scanner software and computer operating system are up to date. Try a different USB port: Plug the scanner into a different USB port on your computer and see if it makes a difference. Reset the scanner: Turn off the scanner and unplug it from the power source. Wait a few minutes and then plug it back in and turn it on. If these steps don't resolve the issue, it's possible that there may be a hardware problem with the scanner that needs to be repaired.

Hello maybe your current driver is vrong or corrupted.

But you have to select your windows system 32 or 64 bit
to make the scanner working.
Uninstall the old driver before you install the new.

Good luck

Check that it is installing to the correct file. Normally C Drive "Program files" I would suggest you go to the control panel and locate and completely uninstall the Epson scanner program first. This will give you a clean install. Check that during the installation, the disc may ask where you want the program to be installed. If it has a suggestion, let it instal itself, where it thinks is best.

Its the lock mechanism under the lid , lift the top to the scan bed and look at the lower right hand side of the inside of the lid there is a grey swithch , move it to unlock! Voila , fixed.

You probably need to reset (not reload) the scanner software. Start the Epson scan software. Select professional mode from the pull down menu (it lets you choose between auto, home and professional.) On the next screen select at the very bottom select configuration. The next screen should have 4 tabs, select other. The at the bottom (I think) select restore to factory defaults. This will reset your software, now you can use auto mode if you want it to make all your selections or home if you want some control or professional if you want to control everything. Don't forget to use your film holder that came with the unit and remove the white cover that is locked underneath the lid that covers the film illumination bulb.

Possible driver issue. You have to reload the twain driver.
To uninstall the twain driver, please follow the ff instructions:

Empty the trash and restart your mac.

You're problem is Vista, not the v500!
