Le linee di taglio

Buonasera,

Invece io ho il problema opposto.
Le linee di taglio ed i margini non si adeguano quando passo dalle pagine dispari a quelle pari.
Ho usato il seguente preambolo:

\documentclass[11 pt,twoside,fleqn]{article}
\usepackage [cam]{crop}
\usepackage[paperwidth=17.5cm,paperheight=25.7cm,voffset=1.5cm,hoffset=1.5cm,textwidth=13cm,textheight=19.5cm,centering]{geometry}
\usepackage[english,italian]{babel}
\usepackage[ansinew]{inputenc}
\usepackage[linkcolor=black]{hyperref}
\usepackage{color}
\usepackage{colortbl}
\usepackage{mathptmx}
\usepackage{amsmath}
\usepackage{isorot}
\usepackage{graphicx}
\usepackage{amssymb}
\usepackage{latexsym}
\usepackage[format=hang,labelsep=period,font=bf,singlelinecheck=false]{caption}
\renewcommand{\baselinestretch}{1}
\renewcommand{\arraystretch}{1.3}
\usepackage{textcomp}
\usepackage{indentfirst}

\makeatletter
\def\ps@plainouter{\let\@mkboth\@gobbletwo
% \let\@oddhead\@empty\def\@oddfoot{\reset@font\hfil\thepage}%
% \let\@evenhead\@empty\def\@evenfoot{\reset@font\thepage\hfil}}
\let\@oddfoot\@empty\def\@oddhead{\reset@font\hfil\thepage}%
\let\@evenfoot\@empty\def\@evenhead{\reset@font\thepage\hfil}}
\g@addto@macro\maketitle{\thispagestyle{plainouter}}
\pagestyle{plainouter}
\makeatother

In cosa sbaglio?

GRAZIE!
