We receive PDF files from our clients; most open fine but some display the following errors:
- Too few operands
- An unrecognized token was found
We have tried using the following versions of Adobe Reader to open them:
- v5
- v6
- v7
- v8
Whilst v5 displays these errors, v8 just displays a blank page.
Any ideas what causes this? I've searched the internet with no luck.
Those error messages mean the PDF is corrupted. With each new version of Acrobat and Reader Adobe has released over the last few years they have tightened up the PDF Spec, i.e., badly formed PDFs that Acrobat and Reader used to be forgiving with no longer work in later versions.
It would help to know what program your clients used to create the PDFs- are they using Acrobat or a clone product? Some clone products could be producing PDFs that don't conform to the spec.
It could also be that the PDFs were corrupted during email transmission- you could test this by having the client ZIP one of the problem files and re-send it to you- if it works that would point to an email problem.
Hope that helps,
Dimitri
