I would not recommend that so freely! It's ok for the connectors, even the internal ones, but the advice sounds like spraying it all over the place, and that is neither useful nor completely harmless. The stuff produces a very fine mist, that might get onto the scanner optics - and stay there. To spray a connector is sometimes useful, but only if you unplug and replug it two or three times after letting the spray sit for a minute (not much longer) on the bare contacts. Don't turn on the unit until the spray is dry (15 minutes).Date: Mon, 03 Feb 2003 08:12:36 -0800 From: Philip Chudy Subject: Re: [PRODIG] Reducing Scanner Noisetry using electical contact cleaner spray on the internal scanner electronics and scsi chain
BUT: I very much doubt contact failure, since that would almost inevitably lead to no scan at all. The pins for transmitting image data are the same as those for sending commands to the scanner, after all. But then, I have not seen the kind of noise that occured. The light source theory posted earlier sounds much more reasonable. Since I noticed rather pronounced scanner noise differences between visualy similar film types (grain aliasing, I think there was a thread about this a few months ago), this might also be a reason.
All the best
