Aldi Tevion Scanner

The scanner was cheap and all expense has been spared in the manufacture. This is the same as the Veho, Ion, Optex 5mp scanner without LCD preview. Due to poor tolerances and lack of adjustments the image was off centre, so there was a fat border at the bottom of an image and a thin one at the side. So it was time to do a bit of surgery.
Here is the brute.

Pull off the rubber feet and extract the two screws.

Lever off the top and gently unhook the four latches that retain it. Two more screws are revealed.

The cover removed, you can see the snapshot button in the top and wires going down to the back light illumination panel.

Looking inside we see the camera. It is held on by two screws and there is no adjustment possible.

The camera looks down at the slide and you can see a Gloucester docks shot out of focus.

Camera alignment was corrected through the use of a custom made polymer spring, precision made out of a memory card case. Pictures no longer have two black edges.

And if you are in any doubt about the quality of this scanner just look at the underside of the snapshot switch. Several layers of double sided strips topped with a paper adhesive tape. This presumably fattens up the button so that it can reach the snapshot switch. As we say, "Quality with a capital K".

I had the same problem with my scanner but by easing off the 2 screws (each side of the push button switch)visible from the top in the picture mentioning Gloucester Docks i was able to move the camera enough to get a full picture with no black stripe. I did this with the scanner plugged in so I could see the effects immediately
