Question about Minolta bizhub 200 All-In-One Printer
I have a Bizhub 200 that I used to be able to access the configuration page for by typing it's IP address into my browser (IE7). Suddenly, I can't get to it anymore; I get an HTTP 400 Bad Request error. Any ideas what gives? Some kind of stealth update to IE or Windows, maybe?
I've been having this exact problem with a C351 and it was driving me nuts... no solutions on the internet that I could find so I started investigating further to find something quite interesting... I ran a packet sniffer to capture the data from a browser that worked, and one that didn't. I then telnet'd to port 80 on my machine and manually sent the HTTP request commands. So, the culprit line on my browser sent:
Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/x-ms-application, application/x-ms-xbap, application/vnd.ms-xpsdocument, application/xaml+xml, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
Now, this was amazing... I'd remove 1 of those entries, and suddenly it would go from this:
HTTP/1.1 400 Bad Request
400 Bad Request
HTTP/1.1 200 OK
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN">
<meta http-equiv="Expires" content="0">
.... (more continued)
So I ran the registry editor on my computer, went to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents, saved this to file, and removed one. I had application/vnd.ms-xpsdocument which I wasn't too worried about so I removed it (I can restore it later should I need it). Sure enough, no the Minolta page loads absolutely find on my internet explorer. You may have to remove more than one entry as the next paragraph will explain why I think this is occuring.
I *think* that the "Accept:" line is too long and the built-in web server doesn't like it. That's my guess. I can remove ANY application/ and suddenly it works. I was easily able to remove 1, if this is an issue with a line problem you may have to remote more than 1 accepted-document. I don't recommend removing any image formats!!!! Also, like I say, backup that key first.
I hope this helps,

After reading through a ton of message boards and seeing a similar problem before, I came up with this and it has fixed my problem on several different machines.
First you need to download and install JAVA. It's free on sun.com
Next you need to remove the following reg key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents\xps
(should say application/vnd.ms-xpsdocument)
Once done, open up internet explorer and type in the IP address of the copier. You should be good to go.

With Java version 5.0 I get the same http 400 error. With the latest version, no problem at all.

Ran into same problem. Fired up a laptop that hasn't been updated in a while and the pages loaded perfectly. Definitely an issue with one update. Has Konica-Minolta said anything in re to this?

The issue appears to be associated with .NET framework 3.0. Does anyone know if there are any firmware updates to correct the issue?

I am almost positive it has to do with one of the Windows Updates, but can't seem to narrow down which one
When I last reinstalled my system, prior to all the windows updates being applied I was able to access my 350 fine. Then, just like my previous system, after I installed all the Windows Updates, I would get the 400 Bad Request Error.
Called my dealer and they have no idea.

Had the same problem. Installed Firefox and it's working now.
