   Canon iRC3200 — Windows SMB Scan Error #751
   

   This is happening at two different customers of mine. I can’t find this error code in the manual for this machine and I can’t find it online anywhere. The only way the customer is able to resolve the issue is to restart the machine.

   Networks differ at each customer. One is scanning to a Win2k3 Server and one is scanning to XP/Vista machines in a P2P network. Scanning will be working fine, and then all of a sudden stop working.

   It will say «sending…sending….resending»… and then sit on resending.

   I am trying to get more information from each customer.

   Can anyone tell me what Error #751 is and how to resolve it?

   thank you!

   There is a possible problem with the scan motor. Not sure if that’s the code you would get

   Possible Work Around
   

   According to Canon:

   Workaround :
   An SMB send job can fail with error code #751 if the user enters forward slashes (/) when specifying the destination. Back slashes (\) must be used when specifying the destination, not forward slashes (/).

   Correct example:

   Host Name: \\192.168.1.33\share

   Incorrect example:

   Host Name: //192.168.1.33/share

   In addition, a #751 code can occur if the destination computer that you are attempting to send to is not running SMB. For example, if you attempt to send via SMB to a NetWare Server that is not configured for CIFS, it will fail with a #751 code.

   Why then does it work sometimes and then fail..rendering the scan feature non-functional until a restart is performed?

   Seems to me like it somehow loses communication to the host it is scanning to… addresses are entered correctly since it DOES work….albeit not consistently.

   It seems to be a SMB communication error… I just dont know what to do about it or even how to track it.

   Also, at the end of the transmission, one customer reports seeing a message blink quickly saying «No Response».

   Why does it all of a sudden lose communication w/ the host?

   follow up
   

   You may have already considered these, but I’ll throw them out for review.

   1. Does the computers that you are scanning to have static IP addresses?
   2. When SMB «push scan» fails, can you still Ping the copier?

   These may not help you, but your responses may help us zero in on the problem. I have never liked SMB scanning to P2P because, like your customers, sometimes the copier has to be rebooted to «see» the other computers on the network.

   Thanks for the input.

   In the P2P install the customer has been having problems with their router not responding to DHCP requests (this is from their IT guy) which would tell me that their IP’s are assigned automatically rather than static. Not sure why this would change anything though since the host name/share would remain the same regardless. They are having a new router installed this week.

   In the other scenario, the scans are going to a server, which is static. They are experiencing no other network problems. The other 2 copiers on their network (non canon) are scanning to these folders w/o any problems. All computers accessing these shares are all terminals (about 50) and have no major network problems…

   In both cases, we can not only ping the copier, but can print to it and receive the Remote User interface through IE.

   It’s very strange indeed.

   One other important discovery I just made was that, when the copier is in this «No scan» state, and go to add a new scan location into the address book by hitting «Browse»… it comes up and says «No Response» or the equivalent… The network is gone…it can no longer «see» the network..but we can see it..

   wth. How can we keep this alive?

   Sounds just like the problem I had on an IRC3200. I had to make the IP a static address for the P2P computer and, if I remember correctly, code in the IP address instead of the computer name for the share — based on Canon’s recommendations. This may still not work, but it is something to ponder. If I think of anything else, I’ll let you know. Good luck!

Canon Error 751: Probable Causes

Before moving to the solution section, let’s check out the possible causes behind the occurrence of the canon error 751.

So that you can take precautions for the next time.

• IP Conflict:- Many times if the IP address is not set correctly, then the printer device can not identify your system. Thus, your system fails to connect with the printer.

Effective Processes to Fix Canon Error 751:

Error code 751 is a common issue and there are other error codes that are similar to this bug. So, if you know how to resolve this technical glitch, then you can fix other error codes as well.

Well, you can restart your Canon printer to eliminate the flaw. However, if this procedure does not work for you, then you have to find out the actual resolving techniques. 

To help you out, here we have discussed the most accurate solutions to deal with this flaw. Now, take a look below.

Solution 1- Check the Server Setting

At first, we advise you to check the status of the server. If the status shows offline, then you have to immediately enable it.  

In short, just ensure that there is no issue with the server settings. Thereafter, verify whether the Canon printer is working properly or not.

Solution 2-  Check the IP Settings

As we have said earlier, in case the IP address is not set properly, then you might encounter this error code. In such a scenario, we suggest you check the TCP/IP settings.

Here is how to check the TCP/IP settings on your system.

• The first thing that you have to do is to tap on the Start button. After that, choose the Settings option to open the Settings window.
• Once the Settings window opens, then drop down and select the ‘Network & Internet’ option to open the Network & Internet properties page.
• Under this section, you will see the Connection type. In case, you are using wired cable, then tap on the Ethernet option. Thereafter, click on the ‘Check Adapter’ option.
• Again a new window will appear on the LED display. Here, you need to drop down and right-click on the Ethernet button. 
• Thereafter, a new pop up menu will show on the display. Now, what you have to do is to select the Properties option to check the status of the TCP/IP.

Also, ensure that the protocol type is selected correctly. Alternatively, you can select the IPV 4/IPV 6 as per the system requirement. Now, click on the OK button to continue the process.

Solution 3- Remove Multiple Copies

While following this solution, you have to remove all the copies from the queue of the system tray. Then, you should cancel out the rest of the documents by pressing the Stop button.

After that, scan the documents one by one and send it accordingly.

Finally, restart your machine and if you are still unable to wipe out the Canon error 751, then give the next solution a try to eradicate the error.

Solution 4- Fix the SMB Server Issue

If the issue is related to the SMB server, then there is a great possibility for the occurrence of this Canon error. 

In such cases, by repairing the SMB server, you can fix the problem. If the process of sending files takes too much time, then you should close the browser screen. After that, scan and again try to send the original files. 

It is highly recommended to check your current SMB version.  To do so, here are the instructions that need to be followed.

• In the beginning, navigate to the Start menu and from there, move to the Command Prompt. 
• After that, enter ‘regedit’ in the given field and press the Ok key.
• Thereafter, type the given command and hit the Enter key. ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters’
•  In case, the status is set to 0, that means the SMB server is disabled and you have to repair it.

So, do the needful and after that, check whether this Canon bug has been resolved or not.
