Bontebok sketch

Bontebok Sketch by Meg Lyman

So, does anyone know how to clean a scanner? Mine has been very good to me, but recently, the dirt on the glass has reached annoying levels. No longer do I have to use the Gimp to clean one or two dots; now they’re everywhere.

When I look at the surface, I notice two things. First, it’s foggy. The fogginess isn’t on the outside, but on the underside of the glass. I have no idea if it needs to be cleaned, or how to do it. It has slowly gotten worse throughout the scanner’s short life. Second, I see little dirty dots. They look green, presumably because of the way the scanner reflects light while it’s idle. But when I go to brush them off, I find that they’re sticky and need to be chiseled off with a fingernail, and mostly they smear all over.

When I scan, I see two undesirable things, both of which have gotten worse recently:

1. Grey areas on the edges. This admittedly may be a problem with the cover.

grey streaks

2. Spots in the scan, per the second complaint above.

I have a nice, soft monitor cleaning cloth that I use on the glass, but it won’t budge the sticky spots, and obviously has no effect on the fog. I keep the scanner covered so well that even cat hair never gets inside.

Does anyone have any words of advice? I paid a lot for this scanner, and I want to run it into the ground - many, many years from now.
