Hi Alan, I recently received my scanner back from Acer, but it still showed the same problems. Here I have an example of an overexposed negative, which gave a perfect fine grained print, but scanning with the Scanwit 2720S is useless for such overexposed negatives as the negative is too dark for the (my) scanwit to scan. I don't know if it is the lightbulb which gives uneven illumination or dust on the lenses, CCD failures etc, but the outer sides of the CCD give too much noise on a dark negative / positive and in case of a negative this results in yellowish banding. Here I show you the scan, downsampled a lot of times. I did use either Vuescan or Miraphoto white balance (which clearly failed, but I know I checked both programs for their results: you get this strange color cast). I didn't try to remove the color cast, but you can still clearly see the yellow / brownish banding along the long edges. The one on the side of the frame where the left door is located is very prominent, it corresponds to the floor side of the film holder as you insert it in the scanner. I sent AcerCM some of my new scans (or links to the scans) made with the 'repaired' unit and they went very silent :-( I don't know if that has to do with vacations or whatever. I think they know they didn't solve the problem during the repairs and they can't solve it without changing a lightbulb or CCD, which is probably too expensive. Unfortunately, my warranty expired during the repair period, so there is not much left to do. I tried some things on my side as well to see if the problem has to do with electronic interference (somebody on this list suggested that some time ago), but I don't know enough about electronics to do some educated tests: I wrapped the SCSI cable in aluminium foil, but it was to no avail. I'll try one last thing this week: hook up the scanner on another group than the PC. This is my last hope. I've seen the monitor flickering, so it could be that the current or voltage is not stable enough in the group of the PC. almost scanwitless, Jerry <<NogSteedsFout_small.jpg>> BTW. I Bcc'd a new contact at AcerCM who was willing to offer some help. I hope he will react, even if it is to tell me he can't help. > -----Original Message----- > From: Alan Womack [SMTP:[EMAIL PROTECTED]] > Sent: Monday, June 25, 2001 6:13 AM > To: Majordomo leben.com > Subject: filmscanners: ScanWit Yellow stain > > Has anyone gotten an answer from Acer on this yet?
