How can we change IP Address from Minolta Bizhub C350?

Utility / Administrator settings (pass:12345678) / Network settings / TCP/IP settings. Select auto IP, or enter it manually. You can check IP address by printing Configuration Page: Utility / User Settings / Printer setting / Print Report / Configuration Page. Press start.
Good luck!

bizhub c350 is not installed properly, the driver you are using are the correct drivers.

Pick set of software that matches your OS, such as windows XP.

Follow install instructions and the printer will show up in your PRINTERS AND FAXES control panel. You can then go into that and set the options you may have, such as the stapler/booklet maker.

You will need to know the printers IP address, such as 198.162.1.10
prior to running installer.

If the printer really is connected to a "hub" (not a "switch", not a "router"), then you'll have to use the controls on the printer to *ASSIGN* an IP-address to the printer.

If the printer is connected to a "switch" or a "router", it should _automatically_ obtain an IP-address. Use the controls on the printer to *VIEW* the IP-address that it obtained.

You can create a scan to FTP one-touch.

log into the device by entering the IP address into your web browser.
From here you can create, edit and delete one-touchs of various types.

I guess you mean the c350 is not printing while Windows said the job has been sent? If so, it may have changed IP Address from the time you first install the Printer on Windows. Check the Ports setting of the c350 printer! e.g.
Network Pritners should have Static IP address or at least a reserved DHCP IP Address. Logon to your Router, check the MAC Address of the c350 and reserve/assign it a IP Address near the end of the DHCP range. Save the Router configuration and power cycle the c350. Confirm IP Address changed to the reserved IP. 

Then you have to change all the PC's Printer Configuration of the c350's Port to update the reserved/assigned IP. Or remove the c350 from Printers and Faxes, then run the printer setup software again.

Easiest way is to change to SMB scanning which will give you direct scanning to PC or server. Create a new address in the machines address tab in the browser add the (must be a fixed) ip address of the machine it is going to with the folder name, user name and password and it will work a treat.

I would print out a copy of the network configuation of that printer and ensure it has the proper network settings (I.E. IP address, Subnet mask and Default Gateway. I just worked on a printer that I accidently pull the plug on and it lost it's network settings and wouldn't print until I changed them back to the correct settings.

Good luck
