Hp HP OfficeJet 7210

I have a HP 7210 officejet. Cannot clear error

I was faxing when I encountered a paper jam. I removed the paper jam. After closing the lid, I get the following message:
'Cover Open, Close Document feeder cover.

I opened the ADF and checked to see if any paper was stuck. I removed the rollers and put them back in the ADF, but I still get the same message.

Is there some type of sensor that is causing this problem.
I can print and receive faxes, but I cannot fax out or scan.

Any help is appreciated...
It could be a sensing lever knocked out of position, or a bent flange, I don't know exactly how that machine is put together.

The cover will usually have a flange that goes through a slot, the other side of the slot will have an optical switch or sensor.

I've had the same error on a 7310--nothing seems to fix it. At the (I presume) location of the sensor (back side of the machine, the rectangular protrusion near the top), my 7310xi is quite hot to the touch.

I have a 7210 right in front of me if you look at the document feeder cover you will see a flange in the rear that goes through a slot to actuate your sensor, check in the slot to see if you sensor is out of position or damage.

more likely the flange was broken off in the process of removing the paper jam :(

The flange looks fine on mine. In a small fit of rage, I picked up and dropped the machine about one inch--and it works again. Not that I recommend this approach for anybody else... - Remy
You guys are all lifesavers. I bought my HP7310 2.5 years ago, and out of the box I had this issue. The unscientific method of applying very slight pressure to the top of the document feeder solved the problem. For some reason I never returned it and then the warranty was done with. Recently my unscientific method stopped working, and this post solved my problem. I used another unscientific method, and bent a paper clip, coaxed it under the circuit board holding the sensor, and pulled hard. I figured I had nothing to lose. I was able to bend it up high enough that it now recognizes the closed document feeder! No more fits of rage, beating on it, etc. I can actually scan again :)
