Adobe Acrobat Pro DC crashes when running OCR on pages with tables
Hi all,
Very annoying error that has hit us recently.
Bit of background - I work for a printing company that carries out a lot of scanning for a large utilities company on a regular basis. The scanning is predominately A4 size and consists of several large lever arch folders of 400 - 600 pages each. Due to the pages been of mixed orientation, and to help reduce the file size, I OCR all the PDF's.
Over the last few weeks Acrobat has started crashing during the OCR process. It will crash on the same page every time. If I set the page range to before or after the offending page it tends to work OK, unless a similar page occurs else where in the document. After carrying out a lot of investigating I have figures out that the error is related to a table that appears on certain pages, scattered throughout the folders. The tables vary on each page in size and content. The tables are not very big, 4 to 5 rows by 9 to 14 columns, but they do contain some symbols like %<*# The quality of the original is OK, its a copy of a copy so the outline of the table is almost invisible but the contents are clear.
This is the error message I receive (sometimes I also get a brief message stating that Adobe failed to send a DCC command):

I tried OCR on another PC with Adobe Acrobat Pro DC and it crashed on the same page, however, when I run OCR on a computer with Acrobat 8, it works fine.
Anyone come across kind of error and any idea for a possible solution?
If I can figure out how to upload a file I will add one of the offending pages for you to try.
Many thanks
Michael
