docling is not providing better results for arabic language

I have been working on arabic pdf.what if arabic pdf consist of scanned images ?.At this stage , we have to classify wheather the page is machine readable text or scanned image.Do we have a to way figure out wheather page has machine readable text or scanned image .
If we are able to figure that out, then we can apply ocr pipeline to that particular page.
I would be grateful, if anyone provide me with required configurations to get better results for arabic language.
