Noise with Pacific Image scanner

[Christophe]

When I use the PIE software Cyberview, the scanner (PF1800u) does'nt make any special noise.
But when I use Silverfast SE v5.2 an horrible squeak appears each time at the start of the scanning.
What should I do to correct this ?
Thanks.

Dear Christophe,
here are the conditions for 35mm FilmScan on Windows:
- latest ASPI layer driver must be installed in Windows system (in ver. 4.6)
- Win98 must be "second edition"
- Windows system file "usbscan.sys" must be installed (search for name).
- these drivers must be installed: ASPI32u.dll and SSCMD32u.dll, SilverFast 5.2.0r09 or higher will install them.

I have the same impression - UMAX PL180 produces "knocs" (a bit horrible knocs, I must say) during initialization before preview/scan - may be it is correspond with activated autofocus feature. Work with CyberView is significantly more quiet (and, noise itself not a problem - but I am afraid that such "knocks" may damage scanner itself).
If you need something to compare - it looks like initial "knock" when Agfa Duoscan series switching from reflective to transparency mode and vise-versa.
Scanner is working, but you heart dissolve in bloody tears each time you hear that...

Hard Noise with PrimeFilm Scanner

Nothing to be afraid of, this is normal with this scanner and is not the sound of something eating up parts inside!
