HP7210 Scanner Failure Help Needed

I have printed 1896 pages on my 7210 and now when I put paper into the Doucment Feeder and press copy or scan, I get a grinding sound and the message Scanner Failure displays. The instructions say to cycle the AIO off then on again. I did that - no success. I did the Semi Reset thing: 1) pulling the power while the printer was on, 2) holding #6 while plugging the power cord back into the wall outlet. Not a fix.

The 7210 works perfectly except for this Document Feeder.

Can you help me or is this AIO toast?
No good news for you...

If the scanner head moves partway across the bed and then you get the grinding noise I think it's a failure of the sensor that reads the tach disc on the scanner head drive motor.

Parts are not available.

You might get really lucky and get it working by cleaning the disc and sensor.

Hi Stephen - Thanks for your input. The solution was "REALLY CLEAN POWER". During the diagnostic work with the HP Help Folks, I had my 7210 plugged into a power strip that also had a desk lamp, CRT Monitor, etc. I was told to plug it into the wall by itself. That didn't work (because the wall outlet, had the power strip plugged into it as well - with all the stuff plugged into it).

After I got off line from HP I started reading this site (fixyourownprinter)and read the "...need for brighter light...". This started me thinking - Dim light - low power ... Hmmmm... I plugged my 7210 into my 1,500 watt power supply and WALLA! No more grinding and the ADF works perfectly now.

Again thanks, Tom
