A clicking (grinding) sound coming from the scanner is caused by the scanner head drive belt slipping, most likely because it cannot find it's index position (or home position). Failure to find it's index position (IP) causes the scanner head to eventually hit something solid causing the belt to slip (grind, grind). The scanner establishes it's IP by detecting a white strip on the underside of the glass on the far right.

Why can't the scanner head find the white strip that it indexes on? There are several possibilities, the main electronics has failed, the scanner head has failed, the white strip it too dirty to be detected, or the scanner head bulb and/or mirror are dirty. (A dirty scanner head bulb or mirror is sort of like me trying to see through fogged glasses).

followed this link to get to the bottom of the glass http://www.fixyourownprinter.com/forums/printer/14863

I have had to clean the printer's white strip, scanner bulb and mirror about every 2 years to keep it going.  The IP sensor must be VERY sensitive to the slightest amount of dust or film of dirt...

This is definitely the correct answer, and has worked in the past.

Sad to say it didn't work for me, but I did find a random post that said I should
1) Turn off the printer
2) Press the scan button 3 times
3) Turn the printer back on

and this allowed me to print again. I suspect this just deactivated the scanner/copier, but I haven't checked.
