| 12222 | 2001-05-06 00:24:00 | About 2 years ago I purchased a new PC (Pentium II, 64 M ram, 6 GB Hard drive, Windows 98 SE) along with a flatbed scanner (CanoScan FB620P). Shortly after I purchased a HP Laserjet 1100 printer. The scanner is connected to the LPT1 port and the printer runs from the back of the scanner. For well over 18 months this system has operated flawlessly. Recently however, following a well documented power outage of about an hour in a wide area of Dunedin I was unable to print. Concerned that there might be damage to one or more parts of the system I began isolating components. I noted that the connection where the scanner (or printer) connects PC was loose. Specifically one of the screws that ensures the cable remains connected to the PC had unwound itself and was attached to the cable. While replacing screw I further noted that the motherboard?? end of the strap running from the port was not sitting tightly. I replaced this. When finished I was once again able to print either with the scanner in the loop or without. However the next time I went to scan I received the message 'Unable to Detect Scanners. Please check that it is connected properly. Error 0x0 The Scanner software troubleshooter suggests that the error lies in power not being properly connected at either the scanner or at the wall socket. These have been checked and a different wall socket used. A graphics program troubleshooter suggests that TWAIN.dll is missing and instructs to copy the file from the source disk to the Windows directory. I have done this. I have uninstalled and reinstalled the software including uninstalling the printer and reinstalling after the scanner is installed. And yes I did disable the virus software while reinstalling. I have since successfully installed and used the scanner on two other PCs using the same cables and software CD. I think that this eliminates the scanner, cable and software as the cause. I have tried 'Add new Hardware' from the Control Panel. On automatic all it finds is a standard modem (and I don't want to complicates matters with this). Under manual search for new hardware the only imaging device it finds is a Kodak Camera (which I have never had). I have looked through the registry entries in the System Information. I can see no reference to a scanner but everything else, (keyboard, mouse, monitor, printer) has entries. No conflicts are reported but my knowledge and experience with this is minimal. One suggestion made was that there might have been arcing where the strap was loose. Before resorting to taking the PC in to servicing, and waiting who knows how long, do you have any suggestions? Is the arcing a possibility? Why will the printer still operate while the scanner is in the line? |

| 12223 | 2001-05-06 22:48:00 | Hi I am wondering if the Bios setting for yout LPT1 port has been changed with the power outage. Check the Bios and make sure the LPT port is using at least EPP for communication. If this has changed then the printer may work and the scanner will not. Have seen this happen before, not due to a power outage though, and this is how I fixed the prob. hth CJ |

| 12224 | 2001-05-06 22:54:00 | Hi This is the second time I have posted this, didn't seem to work the first time. I would check the Bios setting for the LPT port. Make sure it is at least set on EPP. If this setting changed with the power outage then this could be your prob. I have seen your problem before (not caused by a power outage though) and this is how I fixed it. Of course you might have fryed the port but try this first. hth CJ |
