Hello Here is the complete solution to install driver for the HP ScanJet 5100C on Windows 2000 (It should work for Windows 98/ME/NT4.0 I find it on http://bizforums.itrc.hp.com/cm/QuestionAnswer/1,,0xe422cbaac6dcd5118ff40090279cd0f9,00.html And I give the links to download the necessary files ___NOTE__ IT IS QUIT DIFFICULT TO DO THIS INSTALLATION !!! Have a nice time (I loose 5 hours to fix the problems and now everythings work good, scanner and printer) All lines start with _ are mine ******* The instructions on the web site are very unclear. HP support gave me some info plus I found one other fix was needed. I got this all to work on Windows 2000 Server (technically unsupported, but hey it works). You need two downloads: sj269en.exe from the HP web site _From http://www.hp.com/cposupport/swindexes/c5197a_swen.html _(choose your language, in my case french, so download the update file, his name is sj269fra.exe) Epst22k.zip from www.scmmicrosystems.com _From http://www.scmmicrosystems.com/downloads.html?PID=16&s1=8&s2=63 _(choose for your system at page bottom w2k, just above win 98/ME/NT 4.0) AND Download also the software HP PrecisionScan (HP Scanning Software, numérisation) _From ftp://ftp.hp.com/pub/scanners/software/ _french sj263fr.exe (9.54 Mo), english sj263en.exe (17.2 Mo), and other language sj263??.exe Step 1 Run the sj269en.exe and unpack to C:\patch Unzip the Epstw2k.zip into C:\patch (this will replace one file from the previous extract). Step 2 Unplug the scanner and install the HP Scanning Software. DO NOT RESTART the machine at this stage - if you do, you'll get a blue screen of death! Step 3 Run the C:\patch\setup - it will ask for the path to the epsw2k.sys file (enter C:\patch). Move all scanjet hpppt*.* files under the installation dir (typically \SCANJET) into a separate folder - apparently the hpppt.exe causes problems. Step 4 Restart the machine - should now come up without crashing. Follow the instructions about enabling interrupts on LPT1. Step 5 Remove the reference to hpppt.exe in the profile startup. Remove it from the HP scanning software menu. You may also when logging in, get an extraneous explorer window popping up - I found this was caused by the following registry entry: HKLM\Software\Microsoft\Windows\CurrentVersion\Run\hppt Remove the reference to hppt and the window no longer appears after login. _If it doesn't work, perhaps you must change settings in your Bios (Parallel port configuration, disabled EPP, change IRQ...??? you must see) _else I don't know, call HP support... ****** Best regards

this is pogram sent to me thanks see you later
