Hi, firstly let me introduce myself.. I'm a fresh grad students in IT for software development course and recently I just started working as an IT Executive for this factory at Selangor. I work independently here since there is no IT department here and their real "IT" guy is sick and cannot continue his work(Syafakallah and GWS for him). Since I'm from software .. My knowledge for networking is on surface level but I know all the basic for networking lohh don't worry.


Back to the issue.. there is staff here who is his can't connect to the network via ethernet port.. so I try to find solution at google and I change his TCP/IP for IPV4 IP address and DNS address from manually to automatically.. this fix the issue on his network.

But later somehow he can't scan document and got his document directly to his PC(maybe because I've change his IP Address before, p/s : correct me if I'm wrong because I'm not sure).

Do you guys have any solutions? should I call the printer support?


p/s : this company still using windows 7 with 64 bit OS biggrin.gif

and their printer model is Fuji Xerox docucentre-iv 3065

here is the link for images that might help. and thanks in advance nod.gif

Run ipconfig on your pc which has no problem. Compare is this 3 line same. only X should be different, cannot use same number. Can random try from 1-254.
IPv4 Address. . . . . . . . . . . : 192.168.2.x
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.2.1

Your printer already use ip 192.168.2.110. The PC should use other ip which is not in used.

To get ip that is not in use, ping first from your computer that is working 192.168.2.xxx. If got reply then that ip already taken, cannot use.
If the reply is failed/request time out, then you can use that ip.

Hi thanks for the reply.. I try to ping the PC earlier and I got 4 request time out.. what does that mean? do I need to change the IP address at cmd? and how about the network?

If you changed from manual to auto - this means the PC got the address from DHCP. This fixed the access problem because he was given an IP not in use.
It also means that maybe the reason he couldn't access is because his IP was in conflict with someone else IP.

He cannot scan the document because scanning from printer to PC normally relies on fixed IP. (there are other ways to configure this but printer companies always take this shortcut).

If you want to save yourself the headache, yes, you can call them, but they may charge the company for the support call.

What you need to do to resolve all the issues:
- Find out what fixed IP's are in use. If your colleague has documentation, great. If not, one way is to go through the scanning destinations in the printer address book. That should give you a clue as to all the IP's that are being used.
- Configure the machine to use an IP that's not in use
- Update the address book entry for this person to that new IP

Good luck.

your printer screenshot, i believe that is the setting for where to save the scanned document?

protocol is set to ftp, do you have ftp server running on kamel-hp to accept the connection?
maybe you need to use smb instead

first thing first.. did DHCP have anything to do with the router itself? because the other PC is working just fine.. I can just set him new IP address right? and how do I check list of all IP in this network? after that do I need to ping them?

Calling the support call with charge would be the last thing my company would do tbh  biggrin.gif

I get it.. but the PC that have the problem also use 192.168.2.110 and when I set the IP address manually that PC ethernet port cannot access to internet.. the lan cable is working fine since I've tried it on my laptop

when I set the IP & DNS manually (just like before I change it to automatically) then there will be no network for that PC

open up cmd:
netstat ano | findstr /i :21
if you get any result that says listening, then probably you have ftp server running on that machine

you mention that you can print, since your printer is a network printer, then that means that your PC can reach it through the network
that would also mean that your printer IP is not .110 so ignore any comment that says as such

if you don't have ftp server running on that machine, then check if there are any shared folder instead
in cmd:
net share
or you can also run compmgmt.msc, go to Shared Folders -> Shares
if there are any non default shared folder, on printer, set proto to smb and use the shared folder you found on the machine

Ok maybe i make it confuse.
1. At the computer which is working, has no problem to access internet - check ipconfig.
2. At the computer that has problem, no access to internet - copy the same setting from step 1, except you for the part IP Address: aaa.aaa.aaa.xxx, change xxx to other number(do not use the same number).
3. How to get number that is not in used (even by other computer)? - From the computer that is working (Step 1), do ping to aaa.aaa.aaa.xxx (for xxx try number 1-254). if got reply then it is in used. If didn't got reply/time out, then you can use that number.

For printer to machine scan, you need to update the IP address in the address book. (since it looks like these guys don't use SMB destination)

But if you continue using DHCP, when the computer gets a new IP address, you have to update the address book again - which is why it was probably set to manual in the first place.
