In the past, this old scanner has occasionally complained about its
Twain interface after some scanning but would work again after a warm
computer restart. The lid-detect function always worked, though I
couldn't use it.

Now, suddently, using any image program, including the one supplied
with it (iPhoto Plus 4, I get the flag "Flatbed scanner not ready",
and then, in the case of iPhoto Plus 4, I get "Twain error T009; error
opening twain data source T015; unable to find twain source mgr,
twain.dll -- copy twain.dll from source disk to Windows folder T039".
No dialog window now displays when I open the scanner cover. The
illumination lamp is on.

All the Twain and Twunk files are in place. I did copy over the
twain.dll file from the CD supplied with the scanner. No change. I
then uninstalled iPhoto Plus 4 and manually removed all the twain and
twunk folders and files, and then reinstalled iPhoto Plus 4, which
apparently installs whatever software runs the scanner. I have never
found, on my hard drive, whatever the latter is. No change. Since a
Mustek tech-support page says says the peripheral configuration mode
should be set to EPP, I tried that. No change. The scanner has
previously always been used with this mode set to the D850GB
motherboard's default, "Bi-directional".

Mustek also claims that, given such non-detection of its scanner from
an image program, if Windows in Safe Mode does detect the scanner, the
problem is a software conflict. In may case, the problem persisted in
Safe Mode. Actually, I didn't install any new programs between the
time the scanner worked and when it didn't.

I also tried running the copy of iPhoto Plus 4 that I had in the
contents of my previous HD, which I have existing on my present one.
Same symptoms. (That copy of iPhoto was never installed, just copied,
onto my present HD. The same resulted from a backup HD I shoved into
a module for it on my computer, but only set it as a slave. Same
symptoms.

I stronly doubt that the optical lid detector (LED-phototransistor
sensor) has gone bad. Maybe other hardware in the scanner is bad, but
I suspect some silly software problem. Of course, I loosened and
reseated the parallel cable, to no avail. The line-lug-mounted power
supply for the scanner seems to be at its normal temperature.

What could I further check? What files constitute the scanner-driving
software anyhow? How would I get Mustek -- US or Taiwan -- to solve
this problem on this scanner I bought in 1998? ;-) Hmm. It's still
a good scanner. . .once I replace the double-sided sticky tape holding
its glass down -- with metal clips held by screws, so that the copy
would stay evenly spaced from the scanning piece, even with a heavy
book laid on top of it to keep it flat.

You really should check how many times you click "send". There are three in
this NG.
Click only once, it takes a little time for a post to show in the News
Group.

You left out a very Important piece of information, What OS are you running?

For every Twain interface, there is a Folder named the same as the Driver
software name and at least one file in that folder. The one file has a *.DS
name. There may be more that one file in the folder.
The TWAIN driver is located in C:\Windows\Twain_32\Twain_drivername\*.DS
There are 4 Twain files in the Operating System located at C:\Windows named:
twain.dll
twain_32.dll
twunk_16.exe
twunk_32.exe

There are other Twain* and Twunk* files that are scanner specific.
The version numbers must be the same major and minor number. 1.7.? or 1.6.?
1.6.? is used in Window 98 and 1.7.? is used in Windows XP.

Driver for Mustek 1200 III EP is here.
http://www.mustek.com.tw/Download/driv_scanr/html/english.html

Download the correct driver.
Remove whatever you have on your computer now, and install the new driver.
If you are running Windows XP, you are out of luck, it is time to buy a new
scanner.
