I have scanned images which are converted to PDF by some tools. I don't have any control over it. I am now trying to combine those PDF file using PDF::Reuse and when it creates the file, it says it contains the errors.

I don't have any problem combining simple pdfs which are made with htmldoc.

I need to know why this is happening. Any alternative module can provide similar functionality?

Thanks,
Artist.
Update: Here is the code on dragonchild's request.

            prFile($outpdf);
            prText(10, 300, "My Mixbook");
            prText(10, 200, $date);
            prPage();

            foreach (@pdf_files){
                prForm($_);
                prPage();
            }
            prEnd();
