PhotoTime said:I should have read this thread before I clean up the inner side of the glass. I opened once quite long ago, and recently I open again. Scanning normal document seems OK, but when come to scan negative (MF), the image is very grainy, and lights then to fall off at the side. Is there anyway for us to do calibration by ourselves? BTW, I am using Epson 1200U, so it is an old scanner, and not worth to send in for service (I think the service cost will be very exp)

kitkat said:Hi,
It will be difficult (not impossible) to do calibration yourself as the upper housing of the scanner may contains calibration point for the initialization (during rebooting for the scanner). You may have shifted this position point.
Just take a look at 1200U , did u move off any white strip that is at the glass ? There may be a black dot hidden at the edge of the housing which may be damage through cleaning.

fastshot said:To get quality results from film scanning, I should use a dedicated film scanner. Those flat beds just don't have the good enough level of performance for film scanning. Flat beds are fine for occasional scanning of printed materials. In fact I find flat beds are a compromise at best.
For films - use film scanners (Minolta, Nikon, Canon)
For printed materials - use document scanner with document feeder (Fujitsu is great)
I have all 3 types and the flat bed is the least useful.
PhotoTime said:I agreed. But I do not have high end dedicated film scanner to scan MF film, and I heard that flatbed scanner is a good substitute for scanning MF film. So I attempt to scan the MF film using my flatbed scanner, but didn't realised that it is not functioning well until I see the result.

PhotoTime said:Hi,
Just an update to a old thread, in case somebody finds that the glass panel of the flatbed scanner has fungus or foggy.
I am using the Epson 1200U Photo, an old scanner. I do not know how the other scanner works (I do not open and I do not have other scanners for me to explore), but I think that they should be working on the same principle. I.e. The CCD or the scan head is moving with the lamps.
Upon open up the housing, you will the scan head, the black box.
As long as you do not open the CCD, you are save. For my case, although my glass panel is clean, the scanned image is still very poor, so I have to investigate further. I opened up the blackbox, discovered the set of mirrors. The mirror are glued to box, and so, there isn't any risk of changing the angle of mirrors. After all, my mirror is clean, and the front element lens is also clean.
I open the back of the blackbox, and discovered the rear lens element and the CCD.
My rear lens element is foggy. The tedious part is after cleaning, and fixing back the the CCD, you will need to do alignment of the CCD. I am lucky enough to get the right alignment in around 2 times. Afterall, the position is controlled by the screw location, so you can't be too far away, and then, check the preview to see whether is the scan OK. If it is not OK, you will than need to use some imagination and some basic lens theory in Physics (or Photography) to do the alignment of the CCD.
Please bear in mind that I do not bear any responsibility if you open your scanner and spoilt your scanner, as what I described is just what I have done on my scanner. It may not be applicable to your scanner. Do remember that if you open the scanner, you will void the warranty, and you are opening on your own risk.
P.s. Can someone tells me how to show picture in the thread instead of having a URL?
PhotoTime said:Thanks, Geckorian. I just do not want to throw away the scanner, as the scanner motor,and whole scanner seems to be working fine.
I actually wanted to paste the picture in the thread, do you know how? Or only certain people can do it?
