I have gone through the other fixes described in the HP Troubleshooter which also do not work.
I have taken the top off and attempted to clean the shutter wheel but can't find it as it has been described. PLEASE HELP!

In my experience, lubricating the rods does little more than take care of some relatively minor maintenance. The issue IS, or should I say issues ARE, the cleanliness of the glass, the cleanliness of the lens, the cleanliness of the white strip, sometimes the cleanliness of the mirrors AND an oft forgotten item. The last is the plastic wheel on the motor that drives the toothed belt.
This clear plastic wheel with stripes on it is what tells the electronics the position and amount of travel of the scanner head. This is done through a number of stripes on the wheel. When it's dirty, the electronics don't count the movement correctly, the scanner head is mispositioned and in some cases reaches a mechanical stop while the motor is turning, hence the grinding, as the toothed belt jumps on the drive gear.
By the way, this fix works on the G-series, the R-series and some K-series as well. If you're in there, it's probably best just to clean everything and lube the slides - very lightly with a teflon based lubricant.
