We report on two new XMM-Newton observations of the anomalous X-ray pulsar (AXP) 4U0142+614 performed in 2004 March and July, collecting the most accurate spectrum for this source. Furthermore, we analyse two short archival observations performed in 2002 February and 2003 January in order to study the long-term behaviour of this AXP. 4U0142+614 appears to be relatively steady in flux between 2002 and 2004, and the phase-averaged spectrum does not show any significant variability between the four epochs. We derive the deepest upper limits to date on the presence of lines in 4U0142+614 spectrum as a function of energy: equivalent width in the 1-3keV energy range <4 and <8eV for narrow and broad lines, respectively. A remarkable energy depende...
