Epson Rx 420 Printer Not Responding With Win Xp

Hi, I have installed a new epson photo RX420 onto my newly built system but the printer will not print or if it does it will be 15 mins later. It will not even show the ink levels in epson monitor. This printer worked ok on both my other systems which run Win98 and Mill. NOTE: The scanner and card reader on this printer work fine on the XP system. On this new XP system I have two other printers connected which work no problem.
I have the up to date drivers and software installed. I contacted epson help line, but every thing they suggested to me was ok on my system but still no joy. I have no conflicts with any other hardware.
Can someone help please?

 

My friend had this problem on one of his epson printers, we changed the usb cable and it worked fine.

 

Hi,
Have changed USB cable but still the same. Printer just wont communicate with pc, but the scanner side of the printer works fine and so does the card reader. HELP!
