There are a few reasons why your scanner may be taking a long time to scan a document of up to 2000 words.
1. Your scanner may not have enough memory to store the entire document. Many scanners only have limited memory, which could be causing your scanner to take longer to process larger documents.
2. Your scanner may not have a high enough resolution to accurately scan the document. If you are attempting to scan documents with too high a resolution, it can take longer for the scanner to process the data and create a usable file.
3. The scanning software may be out of date or incompatible with the hardware. If this is the case, updating the software should help improve the speed of scanning.
4. The document may contain images or complex formatting that the scanner is having difficulty processing. In this case, it is recommended to run a virus scan on the document before trying to scan it as this may help identify any issues that may be causing your scanner to take a long time.
