[filmscanners] Re: Problems with Minolta Scan Dual II

I have a Scan Dual III and also noticed this. But in my case, it was due to
the scanner's door being between the partway open detent for 35mm holders,
and the fully open detent for the APS adapter. When I tapped the door up to
the 35mm detent, it resumed normal operation.

Perhaps, if the Dual II is the same, the door is not set, or the sensor
mechanism that detects door position is no longer working well.

I have also noted during normal operation, that when the scanner needs to
realign itself with the beginning of the holder, it will kick it as far out
as it can, then retract it again and resume the scanning operation. When
fully extended from the unit, the holder sags about one-half to two degrees
down, so it appears that a perfectly squared-off insertion is not necessary.

My money is on the door sensors at this point.

Here's a link for service centers in the Americas:


Only the primary service facility in New Jersey will service digital
equipment, like the scanner. Ask for an estimate, because it will prolly be

Then consider purchasing a new Scan Dual III. Mine is excellent! Or, for a
little more cash, you can find some model with DigitalICE, the only feature
I wish I had on the Dual III. The Dual III can be had for probably under
$300 now.

When I have experienced what you did, it was often because the holder was
not insertedperfectly square with the scanner in all the directions (right
and left, up and down).  Any variance in any of the directions that might
result in a crooked insertion would cause the problem rewquiring the taking
out of the holder and its reinssertion before  the scanner would accept it.
This would happen if the holder was inserted with the slightest of incline
(up or down) from level as well.

You are right it is a hardware problem not a software one (probably a design
problem which requires much to rigorous and precise tolerances than most
people can act in accordance with with any regularity.

Subject: [filmscanners] Problems with Minolta Scan Dual II

I have been using a Minolta Scan Dual II for several years. Some time
ago I began having difficulty getting the scanner to accept the film
holder and begin a scan. When working properly, the holder is inserted
in the scanner until it "catches" on the internal drive mechanism, which
starts the scanning process. Initially, occasionally the scanner would
not "catch" the holder, but rather the holder would continue to push
into the scanner and there would be slight resistance and clicking
sound, like gears not meshing properly, but nothing "caught" the holder.
If I reinserted the holder, it might "catch" the second time. Over time
the problem got worse (harder to get to "catch"). I began trying several
things (closing and reopening the software, turning the scanner off and
back on, jiggling the scanner door, reciting various incantations, etc.)
and the scanner would eventually "catch" the holder and begin scanning.
Once it started scanning, I didn't have any problem with subsequent
scans. I never could determine just what it was that made the scanner
"catch" the holder.

Now, nothing I have tried will get the scanner to "catch", so it is
useless. Has anyone else has this problem or a suggestion on a solution?
I don't think it is a software issue, since the same thing happens with
Vuescan and the Minolta software (on WinXP Home). It seems like there is
microswitch that isn't working properly, but I hate to start
disassembling the scanner, considering my level of mechanical and
electrical expertise.

I posted this problem on the comp.periphs.scanners newsgroup a couple of
weeks ago, and the only suggestion I got was to push the holder harder
into the scanner until it "catches", but that didn't seem to be
applicable since I can easily push the holder past the supposed start

Is there a  Minolta or other service center that handles filmscanners? I
couldn't locate one through Google, and the KonicaMinolta site doesn't
seem to know about filmscanners.
