Having trouble with HP 3210 All-in-One Printer/Scanner. Purchased printer late 2006. Upgraded to Vista in February 2008. All functions of the Printer/Scanner have been working just fine with Vista until this month. Error message says 'Unable to Scan or Copy'. Scanned from computer on 12/01/2008 and a week later the error message appeared. Print function from the computer works fine. Buttons on front of the printer for both scan and copy will not work and scanning from the computer will not work. Have tried suggestions from different websites to work-around using a program like Microsoft's Paint but still nothing. Any suggestions will be welcomed.
