I have an epson expression 1640 xl scanner. when i turn it one - no problem at first . the operate light and ready light both boot up and stay green. then i open the epson scan wear and press the preview button. The scanner starts to scan - idincted by a bar that moves accros with message saying 'peview scan in process' but a second or so later i get the following message No Response from the scanner. Make sure the scanner is on and properly connected. If using the transparency Unit, remove the reflective document mat. At the same time the RED ERROR LIGHT on the scanner starts to flash. I have tried checking all the cables are in properly. I have switched the scanner machine off and rebooted the computor but this does not help. I have tried looking at trouble shooting on linee and only got the following information in relation to red flashing lights. That is to make sure the transport lock on the scanner is in the unlock position. I did this but no help. I have tried phoning epson scneer technical team who say the red flashing light indicates a mechanical fault. Has anyone else experienced this problem. Is there anything else i can try before spendoing a fortune on repair or replacment. I purchased the machine in 2001. THANKS
