Question about AcerScan 620PT Flatbed Scanner
Recently moved scanner to a new computer. Installed the XP driver from BenQ site as Acer no longer supports this 10 year old printer and the scanner division was taken over by BenQ a while ago.
I can no longer select between reflective and transparency images as this menu choice is grey and is set to only scan reflective. I use this scanner for scanning x-ray films (transparency).
I recall that this was also a problem in the original setup many years ago but can't recall the fix(ya) on how to allow for transparency scanning.
Can you put some backing on the transparency and scan it like a regular item?

I'm having the same problem with my scanner Primascan Colorado 2400. Looking for a solution I landed on this page.
Website of scanner:
Answers there: nihil.
I bought this scanner some years ago. Worked very well with WindowsME, and until yesterday as well with WindowsXP-SP2 on my overall usually very compliant and compatible modern computersystem.
I used to scan from IrfanView. It always called the scanmanagerprogram very satisfyingly.
But as of yesterday following error-message:
(translated from Dutch) "Can't find entrypoint of procedure _P_ImageDownSample@24 in DLL-file ImgProc.dll."
I've noticed that WindowsXP has two ImgProc.dll's in \system32.
One from the scanner-installation and one probably installed with WindowsXP.
I've installed and reinstalled this very decent scanner several times. And it gets wel detected, without hardware-conflicts.
But, as it worked perfectly before on this same system, it suddenly doesn't anymore.
Maybe I will come back here when I've found the solution if noone else has by that time.

I can only speak from experience but I have found HP to be one of the best for what you need.
