It looks like I dug up an old thread while trying to find the solution to the same problem. The printer I am using is a Minolta QMS Magicolor 3100.
Basically, out of the blue one computer stopped printing, and displayed the following message:"Function address 0x834e74c9 caused a protection fault. (exception code 0x0000005) Some or all property page(s) may not be displayed."
My Googling lead me to a Microsoft KB article
that described my problem. However, this
article describes it more accurately, however it is intended for Windows 2000-based PCs. Aside from not opening the properties of the printer, I get the following message when trying to print from Word: "Microsoft Office Word has encountered a problem and needs to close. We are sorry for the inconvenience.
To see what data this error report contains, click here."
I get the same error using USB or as a networked printer. (The printer has a built-in Crownnet NIC and connected to a DI-624 Wireless router). I have a second computer configured the same way and it works without any problems. It has to be something with this printer or related drivers. I have a second Brother MFC printer also with networking built-in and that works with no problem on the "problem computer."
I have reinstalled the drivers and the network printer port several times, and followed Microsoft's KB article referenced above. I even had this problem prior to reinstalling Windows (because of other issues on this computer). I spent about an hour on the phone with Minolta and applied the hotfix from Microsoft that I had to receive by e-mail described in that KB article.
I'd appreciate any thoughts or advice. Hopefully someone has encountered the problem and been able to solve it.
