Unfortunately, you cannot upload a document here, but you can use a public file sharing service from e.g. Acrobat.com or Dropbox.com and then post the link to this file here.
Without having seen the file, I would guess that there is something wrong with the image on these pages (e.g. a corrupt TIFF image that only shows the problem once OCR is executed). Do all OCR options give you the same results?
