There could be a few reasons why your scanner is not completing a scan up to 2000 words. It could be a hardware issue with the scanner, such as a power or connection issue. It could also be an issue with the software, as scanners require specific software to work correctly. Alternatively, it could be an issue with the document you are scanning. Ensure that the document is in focus and properly formatted for the scanner to read it correctly. If none of these solutions work, you may need to contact the manufacturer for more help.
