The front panel on my printer will not close. model S305 how can I close it?

SOURCE: I have just bought a Lexmark S305 Impact

Try as I could (Using a mirror and flashlight and feeling all around), I couldn't find a 'Lever' anywhere, but what I finally did find was that there are three thin molded plastic lines right there up under the center back of control panel. While holding the top of the printer (above the panel), and using one finger, I pushed up hard on those plastic lines. After a moment of pushing on them, I heard a 'click', and that released the panel so now it moves up & down again. It can be adjusted at whatever angle I like just like before it locked. If I want it to remain up, I just lift the panel all the way up until I hear that 'click' again. Hope this helps.

find a tight plastic locking clip on the underside of the control panel. It may be at the top middle edge on the underside. Give it a very firm upwards press and it should unlock the control panel section.

We had same problem and this helped us. But you have to move your finger just to the right of the ridges and press firmly- you'll hear it click as it releases
