The Scanning Speed Is Very Slow

Does your computer meet the recommended system requirements?

If the CPU or the memory does not meet the recommended system requirements, the scanning speed slows down.

For details about the recommended system requirements, refer to System Requirements.

If the scanning speed is very slow even when the recommended system requirements are fulfilled, changing the scan settings may improve the scanning speed.

For example, when documents are scanned with the setting that creates a searchable PDF file, it may take time to link to the application because the characters on the scanned image need to be recognized.

If necessary, change the settings in the following procedure:

Is [Excellent] selected for the image quality level in the scan settings?

If you select [Excellent] for the image quality level in the scan settings, it may slow down the speed of scanning documents depending on your system environment.

If you scan a document with the setting configured to detect a document type automatically, and with [Excellent] selected for the image quality level in the scan settings for one of the four document types ("Documents", "Business Cards", "Receipts" or "Photos"), the scanning speed for the other types of documents that [Excellent] is not selected for slows down.

If there is a specific document that you want to scan with [Excellent] selected, create a profile with a document type selected which is suitable for the specific document, and with [Excellent] selected for the image quality level.
