Digital BW, The Print

I have an Epson 1280 with which I use a MIS VM inkset.  Lately, it 
appears to have some ink on the underside of the head and as it 
passes over the paper, it creates ink smudges.  I remember 
reading something about cleaning the bottom of the head with a 
paper towel soaked with Windex, but I don't remember exactly 
how that is done and I can't seem to locate the old message.  
Any advice would be greatly appreciated.
Thanks in advance,
