Scanner Glass dirty

If when the scan head lights up and makes a warm‐up pass you see what appears to be Haze, or even very thin mildew on the underside of the glass then you may be very puzzled and it make no sense at all because your scanner resides in a clean, dry atmosphere, and always has.

The problem is a common one.

What happens is the plastic of the case is always releasing minute particles of gas which settle on the inside of the glass.

This can give the appearance of dirt or mildew.

The answer is to take the scanner apart and clean the glass.

That is if you can work out how the d*** thing fits together, and not break the plastic clips in the process.

Always remember if there are no screws and even where there are screws someone has had to push it together.

So approach the job from the aspect that if it was pressed together it can be unclipped, and that it is very unlikely to have been glued together.

The plastic clips usually have a step on them and so it means pushing a part of the plastic case one way to allow the clips to release themselves.

Patience and logic are the tools which you must use in these situations.
