I had some troubles with setting margins on document, so a made this function to update all margins.
This should be called before add page. 

        function    refreshMargins($left,$top,$right=-1){
            $this->SetMargins($left,$top,$right);
            $this->pgwidth = $this->fw - $this->lMargin - $this->rMargin ;
            return  true;
        }
