Mustek 1200 III EP undetectable in any image program
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.

Ray It is sort of hard to follow the two prior messages and understand who has the problem, but perhaps I can help? I have the same scanner and have installed it on Win 98 and XP. Which OS are you dealing with? If all the software loads without a problem, there should have been a test to see if the scanner was detected. I assume you reached that point and it was NOT detected? Do you know that the parallel port your scanner is attached to works? You might want to attach your printer without the scanner to prove in the port. If you are using the pass through method (where the scanner is the first device on the port), I would remove the printer after you establish the port works, and get your scanner working by itself. In my case, I had so many problems with the pass through method that I installed a second parallel port in my computer. That solved a lot of problems. But first just get the scanner to work with a single port and no printer attached. Make sure your data cable is attached to the correct connector on the rear of the scanner and to the working parallel port on your computer. (Recently I took my scanner to a friends house to establish if her scanner was bad, and upon re-attaching my scanner hooked the data cable to the wrong connector on the scanner. I encountered the same type of problem as you have. Duh!!) Also check that your PS is getting power when you try to run the scanner. You could test the output with a DVM. The lamp on the scanner is controlled by the software if I recall correctly, so I don't believe it will come on unless the scanner is detected via the parallel port. Detection is also dependent upon the power reaching the scanner so that it can respond to the software. C:\WINDOWS\TWAIN_32\A4S2_600\WATCH.exe is the file that should turn on the scanner lamp. C:\Program Files\iPhoto Plus 4\PROGRAMS\IPE.EXE is the file that start Iphoto4 software. You could go to the individual files and double click on them to start the sequence. Write back after you see if your port is good, the software is present, the data cable is attached properly, and maybe I can help more. |

I have the same scanner and have installed it on Win 98 and XP. Which OS are you dealing with? Win98SE If all the software loads without a problem, there should have been a test to see if the scanner was detected. I assume you reached that point and it was NOT detected? I don't recall its having included that test. I do know that immediately thereafter, on trying to "Acquire" the scanner, I got the stated error messages. Do you know that the parallel port your scanner is attached to works? It was working with the scanner the last time I used it -- I think the day before. I did not try to use it with any other peripheral between times, or even remove either end of its cable to the scanner. You might want to attach your printer without the scanner to prove in the port. My printer uses USB. I found out some time ago that my printer (HP 5650) won't work right with a parallel bus chained through my scanner. I don't think it will work right, in the mode I'm using it, with a dedicated parallel bus. It's hard to believe that my parallel bus suddenly quit working, when I didn't touch its connections at all. If you are using the pass through method (where the scanner is the first device on the port), I would remove the printer after you establish the port works, and get your scanner working by itself. I don't have a pass-through hookup. The scanner is on my only parallel computer I/O and my printer uses USB only. In my case, I had so many problems with the pass through method that I installed a second parallel port in my computer. My old HP 932c printer USUALLY worked OK with that hookup, but I had to be told that the reason I couldn't get my new much-faster printer to work right, in that configuration, was due to that kluge. Luckily, I had an extra USB port (but a 7-ft cable just barely makes to the location of my printer. That solved a lot of problems. But first just get the scanner to work with a single port and no printer attached. Make sure your data cable is attached to the correct connector on the rear of the scanner and to the working parallel port on your computer. Yes, I haven't changed either connection since it worked. My computer has only one parallel I/O connection. (Recently I took my scanner to a friends house to establish if her scanner was bad, and upon re-attaching my scanner hooked the data cable to the wrong connector on the scanner.

You could test the output with a DVM. The lamp on the scanner is controlled by the software if I recall correctly, so I don't believe it will come on unless the scanner is detected via the parallel port. No, no, no! The lamp stays on on this model, whenever its plug is engaged with a hot power strip. Since this lamp stays lit, power is at least getting to part of the scanner. Detection is also dependent upon the power reaching the scanner so that it can respond to the software. C:\WINDOWS\TWAIN_32\A4S2_600\WATCH.exe is the file that should turn on the scanner lamp. It can't be for that purpose, because the lamp, as stated above, is ALWAYS on. Watch.exe is installed at that location [vers. 1.0.0.1, 180K]. C:\Program Files\iPhoto Plus 4\PROGRAMS\IPE.EXE is the file that start Iphoto4 software. You could go to the individual files and double click on them to start the sequence. I have done that with Ipe.exe and it brings up iPhoto 4 fine. I just did that, then clicked 'Start', in that program's main window, and then 'Scan'. The source window came up properly as it still has done starting from the Desktop item. Then, instead of clicking 'Acquire' in that window, I double-clicked Watch.exe in Windows Explorer. Absolutely nothing happened; I didn't even get any error flags. Write back after you see if your port is good, the software is present, the data cable is attached properly, and maybe I can help more. If YOUR scanner doesn't keep its illumination lamp on at all times that scanner is plugged into an AC source, you have a different model than mine, because I was informed by Mustek USA once (when I complained about the lamp's needless usage [I had to replace it once.]) that that is how the scanner I have is supposed to work. If this is a hardware problem on the scanner's circuit board, I suppose I'm out of luck, unless I run across a junked such board somewhere. Fat chance. I certainly don't think trouble-shooting at the board's component level is reasonable. But I think it's a software problem. (Naturally, I'm a retired hardware type.) I just wish I understood exactly which software files are involved in detecting the scanner IN MY EXACT UNIT. Ray |

I have the same scanner and have installed it on Win 98 and XP. Which OS are you dealing with? Win98SE Ray, That is the same OS that I use most of the time and am using now. If all the software loads without a problem, there should have been a test to see if the scanner was detected. I assume you reached that point and it was NOT detected? I don't recall its having included that test. I do know that immediately thereafter, on trying to "Acquire" the scanner, I got the stated error messages. It might be that the test occurs after it detects your scanner as being present? It has been a while since I installed the software, but there is a test during the installation. I thought it asked you if you wanted to do such a test? It really is a moot point, since detection would come first anyway. Do you know that the parallel port your scanner is attached to works? It was working with the scanner the last time I used it -- I think the day before. I did not try to use it with any other peripheral between times, or even remove either end of its cable to the scanner. I don't mean to be sarcastic, but often people assume that what worked yesterday still works today. In trouble shooting you must take nothing for granted and establish one building block at a time until you reach only one possibility left. Until it is established that it works on a printer, it is still a possible cause of your problem. You might want to attach your printer without the scanner to prove in the port. My printer uses USB. I found out some time ago that my printer (HP 5650) won't work right with a parallel bus chained through my scanner. I don't think it will work right, in the mode I'm using it, with a dedicated parallel bus. It's hard to believe that my parallel bus suddenly quit working, when I didn't touch its connections at all. So much for the pass through option. It is good to know that the cables have not been moved however. That doesn't mean they are good, just not connected improperly. If you are using the pass through method (where the scanner is the first device on the port), I would remove the printer after you establish the port works, and get your scanner working by itself. I don't have a pass-through hookup. The scanner is on my only parallel computer I/O and my printer uses USB only.

Make sure your data cable is attached to the correct connector on the rear of the scanner and to the working parallel port on your computer. Yes, I haven't changed either connection since it worked. My computer has only one parallel I/O connection. As suggested above, I would establish the parallel port functioned properly on some other device. The CMOS settings should of course be EPP or ECP (bi-directional) and not standard parallel port. (Recently I took my scanner to a friends house to establish if her scanner was bad, and upon re-attaching my scanner hooked the data cable to the wrong connector on the scanner. I encountered the same type of problem as you have. Duh!!) Yeah, well, I didn't touch MINE. It went south by itself. ;-) Also check that your PS is getting power when you try to run the scanner. You could test the output with a DVM. The lamp on the scanner is controlled by the software if I recall correctly, so I don't believe it will come on unless the scanner is detected via the parallel port. No, no, no! The lamp stays on on this model, whenever its plug is engaged with a hot power strip. Since this lamp stays lit, power is at least getting to part of the scanner. The lamp might come on by default, but it should come on when the WATCH.exe is executed. When you load the installation software, this command is installed in your startup list. My guess is the icon for the scanner is in the bottom right hand corner indicating the scanner scan software is started. In my computer I stopped the scanner software from starting and created a batch file to start it only when I want it started. Seeing the light on would indicate a couple things however: First, power is getting to the scanner. It might not be the 15 volts that it is supposed to be, but it PROBABLY is. Secondly, it does indicate that some of the parallel port works if you can control it as mentioned below. It might not be working 100%, but some of it must be working. Detection is also dependent upon the power reaching the scanner so that it can respond to the software. C:\WINDOWS\TWAIN_32\A4S2_600\WATCH.exe is the file that should turn on the scanner lamp. It can't be for that purpose, because the lamp, as stated above, is ALWAYS on. Watch.exe is installed at that location [vers. 1.0.0.1, 180K]. If your light is on for the scanner, check to see if the scanner icon is in the bottom right hand corner of your screen. Right click on it and choose EXIT, YES. Did the light go out? Go to the WATCH.EXE file and double click on the file. Did it come on again? If so, you can control the light through the software. C:\Program Files\iPhoto Plus 4\PROGRAMS\IPE.EXE is the file that start Iphoto4 software. You could go to the individual files and double click on them to start the sequence. I have done that with Ipe.exe and it brings up iPhoto 4 fine. I just did that, then clicked 'Start', in that program's main window, and then 'Scan'.

Absolutely nothing happened; I didn't even get any error flags. If the icon for the scanner is not in the bottom right corner, the WATCH program did not start. If is there, then start IPE.exe and go to FILE, ACQUIRE, SELECT SOURCE and your scanner should be listed there. Is it? Write back after you see if your port is good, the software is present, the data cable is attached properly, and maybe I can help more. If YOUR scanner doesn't keep its illumination lamp on at all times that scanner is plugged into an AC source, you have a different model than mine, because I was informed by Mustek USA once (when I complained about the lamp's needless usage [I had to replace it once.]) that that is how the scanner I have is supposed to work. You are right, the light comes on by default. I used the batch file to control the scanner and only plug in the power when I am about to use it. The control of the light with WATCH.exe is valid however. Run the test above and you should be able to turn it on and off. If this is a hardware problem on the scanner's circuit board, I suppose I'm out of luck, unless I run across a junked such board somewhere. Fat chance. I certainly don't think trouble-shooting at the board's component level is reasonable. But I think it's a software problem. (Naturally, I'm a retired hardware type.) I just wish I understood exactly which software files are involved in detecting the scanner IN MY EXACT UNIT. Anything is possible, but I would not arrive at that conclusion yet. Ken Ray |
