Margin of a Document iTextPdf

Question

I am working with an existing PDF file, follow the small line of code:

    //Código...

    document = new Document(PageSize.A4);
    PdfWriter writer = PdfWriter.getInstance(document, fOut);
    document.open();
    PdfContentByte cb = writer.getDirectContent();
    // Load existing PDF
    PdfReader reader = new PdfReader(arquivo);
    PdfImportedPage page = writer.getImportedPage(reader, 1);
    document.setPageSize(reader.getPageSize(1));

    //Código...

My problem is this, I’m using the element Paragraph of iTextPdf and aligning each String in its proper place in existing PDF file using these methods:

    paragraph.setIndentationLeft(94f); //Movimenta horizontal
    paragraph.setLeading(14f); //Movimenta vertical

However, by placing a String more to stretch or right is as if there existed a margin, a space of approximately one inch that I can not overcome, the String break and continue below it or on the same line, I suspect it is some configuration of the element Document, I used the following methods unsuccessfully:

    document.setMargins(0, 0, 0, 0);
    document.setMarginMirroring(true);

Would anyone know how to RESET that margin??? I want to add one String right on the "edge" of the archive.

The Document.setMargins() only acts on the next page. To act on the first page it is necessary to call it before the open.
