CanoScan 9000F – Gliding Part Slides when Tipped "Scanner reported an error"


I purchased a used 9000F scanner, and they didn't engage the lock switch. It doesn't appear to be physically broken, but when unlocked, the part that gets locked down freely slides front to back when tipped. It powers on, and when I attempt to scan on my Mac (macOS 12.2.1, Intel) I get the message "Scanner reported an error: Release the lock switch, turn the device off and then back on." The lock switch is unlocked, and I've attempted rebooting both the computer and the scanner.

Does it sound like it's physically broken, or is it possible there's a software error happening? If it sounds like the gliding/sliding part is misbehaving, is it possible to fix?
