Chapter 44-14.1 Notes when service4.1.1 Points to Note 0008-4678If it becomes necessary to perform memory clear (MMI CLEAR) during service, then in order to save theuser's network settings and address settings, etc., always make sure that you print out the user data list (net-work) and address lists, etc., from user mode. And, before printing out any address lists, make sure thatyou explain the need for this to the user and obtain the user's consent. Further, if it is possible to use aremote UI, exporting and backing up address lists, transfer setting and other user mode contents will assistin recovery in the event of any problems. For a user who uses two or more imageRUNNERs/iRs, use ofthe device information delivery, new feature, will be a good solution.4.2 Troubleshooting4.2.1 Troubleshooting 0008-4679Basic troubleshooting procedures related to the SEND function are described below.Where an error message or error code is displayed, refer to the appended error list and check the appropri-ate countermeasure. The error list is divided by function, as per the following.E-mail transmission/ I-Fax transmission/ I-Fax reception/ transmission/FTP transmission/NCP transmis-sion.When a problem occurs, the first step is to identify with which function the problem occurred and thencheck the error list for the appropriate countermeasure.If the location of the problem cannot be identified form the error message or the error code, the followinginformation may be of help in determining whether the cause is in the network, server or iR.Check the following items.- Use the Ping command to check whether the appropriate IP address (an address that can be used to checkwhether the DNS server, SMTP server, POP server, etc, are operating properly) responds.- If there is a response, move on to check whether the cause is in the server. If there is no response, checkthe network cable connection, the network board status and the network hub status. If a PC can be used,take the cable that is connected to the iR and connect it to the PC and try connecting to the network fromthe PC. If connection fails, it may be assumed that there is a problem on the network side.- With SMB transmission, it is sometimes the case that transmission on the PC to the network is possiblebut reference is not. In that case, it is necessary to gather information about the user's operating environ-ment. The following is an example of the user's operating environment and possible cause and counter-measure, when it is not possible to reference.Reference information:Operating environment when SMB browsing (reference) is not possibleWhen transmitting files with SMB with the following operating environment, it is sometimes the case thatthe addressee's browsing (reference) function does not work well.- Around 50 PCs (Windows XP/Windows 2000/Windows 98/Mac OS) all obtain IP addresses via DHCP.There is no domain controller or other server and the network is made up of 10 work groups.Problems likely to occur with this kind of set up include, with regard to SMB browsing (reference) fromiR,- even if referencing is performed, there is absolutely no display,- the function extends as far as the work groups, but some work groups are excluded.How this problem is causedThe Windows network automatically assigns one machine in each work group as the master browser.However, in the above environment (each PC gets its IP address from DHCP and there is no server) theassignation of the master browser may become unstable. The IP addresses obtained from DHCP some-times change and there are periods where the master browser cannot be assigned because PCs are beingswitched off and on, so the information being held by the master browsers gets mixed up, leading to theproblems described above. In this environment, even if a WINS server is programmed, in work groupbrowsing there is no query made to the WINS server. This is because the WINS server does not return
