My client has scanconnect with their LF client, and uses a Canon DR-9080C scanner. The scanner was working fine until recently the scanner will always freeze in the middle of scanning. Usually after it freezes, I have to manually close LFScanning, and the ScanConnect91 program in the task manager. Once I got back in, the scanner gives a message about it not being able to connect to it. After restarting the computer and restarting the scanner, we are back to square one. I have downloaded the latest canon driver, did a complete uninstall/reinstall of LF and scanconnect, and changed USB cables. The client also had the computer rebuilt, and tried the scanner with a different computer but the issue still comes up. Unfortunately the client only has this scanner to work with, no other scanners to test. There are no related error messages in the even logs, and the only ones I could find where in the output log in LFScanning:  "String not found (-4630) Error Initializing "DR9080C: Scanner Driver (-4630)". TWAIN works fine, but they client needs ISIS for specific settings that aren't available in TWAIN. I even tried another scanning program(NAPS2), and it worked fine(it doesn't support ISIS). At this point I'm leaning toward the scanner, but nothing seems to fit. Just wanted to know if anyone else has encountered this issue and if they found a solution for it.

LF: 9.2.1.5...(can't remember the last 2)

ScanConnect: 8.3

Driver Install: 5.50.137.0
