Which my quick translation to English gives... E041 Paper Tray Cartridge - Defective feed motor - Defective position sensor - Defective controller card Hope this helps. Cheers, Rob. _________________________________________________ For information concerning the MUGLO List just click on http://muglo.on.ca/pages/members.html#Joinmuglo Don't forget to periodically check our web site at: http://muglo.on.ca/
