Adobe save as image error

I have struck an interesting problem with a regular report that I receive. When I go to save some of the pages as images (so I can copy them into the appendices of my own reports as evidence), I get the following Adobe error. 

 "Adobe could not save the page in this document because of the following error:" "The image is too wide to output. Please crop it or reduce resolution and try again". 

The trouble is the page is not too wide. There are no objects off the edge of the page. I tried cropping the page. That didn't work. I tried extracting each page as a separate pdf, then trying to save each page as a jpg individually. That didn't work. I tried doubling the page size to A3. That didn't work. I tried copying the components to a new document. That didn't work. I tried decreasing the output image to 300dpi. That didn't work.

So in the end I tried my fix for an Adobe file which won't print. And that worked. The repair is as follows:

1. Open the pdf in Adobe Acrobat
2. Go to File | Export To | PostScript (not an encapsulated PostScript file; just a plain PostScript)
3. Save the file with the desired name/location (changing the name if the original file is also in this folder is a good idea, otherwise it will be overwritten in the next step)
4. In Adobe Acrobat, go to File | Create | From File. Select the .ps file and save as pdf. The new pdf will be saved in the same folder
5. Check to see if the error still occurs, by having a crack at deleting a page.

While I have written about this error before (here and here), and I hope this helps someone else!
