  Printer is now fixed and working fine. Thank you very much for your help. (I have already \"recommended \" your site to a friend who was having a problem with his printer. Further if (when) I have a problem with any of my other printers, (Canon S600 and Cannon i560), if a manual is needed, I will revisit.

  I must admit I was very skeptical about all this !!! And above all - There we go, they want the Credit Card details !!!

I don't even know the current exchange rate but proceeded thinking nothing will come of this ....

Within minutes I was sent the RESET CODE along with the RECEIPT FOR PAYMENT !

It worked like a charm !

The FIRST , but definitely not the LAST time I will be using this site !

Thank you !
