In the past, I've either used image capture or scanned directly from the scanner in system preferences by opening the scanner webpage. For the past few months, I get the message in image capture, "failed to open a connection to the device (-21345)". I've disconnected and reconnected printer/scanner on several different occasions, but still can't figure out why I can't scan multiple pages.
MacBook Pro 13″, macOS 10.13
Hello, paynelandgraf.
Sorry that you're having this problem with your Mac.
Are you using macOS 10.13 High Sierra as indicated at the bottom of your post?
Have you applied all available updates (not upgrades) so are now running 10.13.6?
What make/model scanner are you using?
Have you visited the mfg's website for any driver/scan software updates?
If you have installed any anti-virus, "clean up" or optimizing software, try disabling or uninstall that and see if the situation improves. Apps of this type often interfere with the normal operation of macOS and cause more problems than they prevent.
If rebooting your Mac doesn’t fix things, see if the problem still happens in Safe mode (hold the shift key down at startup). It can take much longer to safe boot (10 min) so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode disables loading third-party drivers, forces the OS to clear certain caches and logs and does other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's expected.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again.
