Digital BW, The Print

I hope you consider this on topic.  I just purchased this my second 
V700, having returned the first one because the on light continued to 
flash red.  The second one does the same.  Both times I have spent 
considerable time troubleshooting with Epson with no success.  I have 
a fairly new and powerful Windows XP computer.  It is connected via 
USB2.  I've tried 3 differed USD cables.  Has anyone experienced the 
same problem?  Any suggestions?  I would Really appreciate any help.  
I have borrowed 97 75-100 year-old glass plate negatives, which I have 
to return tomorrow.  Nancy
