Yesterday I was scanning some documents using devonthink PO. All was working fine, but suddenly I got an error in OCR import telling me that the scanning I was doing has got 0 DPI instead 300,and asking me to skip, import, or ORC anyway. If I choose OCR anyway the process do not work, if I choose to import I can keep scan, but with no OCR process. Changing DPI or TEXT/color do not change anything, until i restart DPO.
For me It’s the same behaviour of DTPO since I use the OCR (since v. 1.4). The only way for me to use the OCR is to import the pages without OCR and after that to convert it to a searchable PDF.
I too have ocr problems. Some files crash the RDE process.
The crash log says
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000
among other things.
It only happens on certain files but I have not found any common denominator for them. Its not the size of the file (which I thought for a while) since this happens on pdf containing ten pages as well as fifty pages.
It would be nice if you can send an example image file that has the resulting error about 0 dpi to support@devon-technologies.com.
About the RDE crash: there are certain PDFs that cause crashes. This is of course a bug in the IRIS software and we are always reporting these to them. So send it to support as well if you can.
