There are a few potential causes for slow scanning of documents. These include:
1. Low system resources: If you’re running a lot of programs or processes at the same time, your scanner may be processing slower than normal. Check your memory and processor usage to make sure that you have enough resources available.
2. Resolution settings: Your scanner may be set to a high-resolution setting which is taking up more time to scan. Try reducing the resolution you are scanning at and check the speed improvement.
3. Outdated software: If your scanner software has not been updated in a while, it could be causing the slow performance. Check online for any available updates and install them.
4. Dust build-up: Dust and debris can cause obstructions in your scanner and can result in a slower scan. To clean your scanner, refer to the manufacturer’s instructions.
