Image processing can improve the result, but this typo is very particular, i.e. "unconnected" digit. I try morphological transformations to re-connect digit, better (*tesseract ocr_inv-8.png ocr-8 --psm 6*) , but yet far away a proper result. According to me, train *tesseract* with this typo is a way.
