Troubleshooting the Unified Client for Konica Minolta

This chapter provides information for troubleshooting problems with the Unified Client for Konica Minolta.

Error codes

If the Unified Client for Konica Minolta returns an error code, refer to this table for an explanation and resolution.

Error Code Explanation and Resolution
2236 The certificate security credentials cannot be verified. Configure the device to accept the Web server certificate from DWS. See Certificate acceptance.

Device registration issues

If a device fails to register or unregister in DRS, check the following:

  • Make sure the device is not in an error state (such as from a paper jam or out of paper) before registering or unregistering the client on it. If the device is an error state, registration or unregistration will fail.

  • Make sure no users are logged on to the client before using the the Install and Configure or Update Configuration action.

  • If you are using Unified Client for Konica Minolta with the Combined Client for Konica Minolta, register the Unified Client for Konica Minolta first. If you attempt to register Unified Client for Konica Minolta when the Combined Client for Konica Minolta is already registered, credential fields will not appear when you start Unified Client for Konica Minolta. If you already have the Combined Client for Konica Minolta installed, remove it and then register it again after you install Unified Client for Konica Minolta.

  • Do not select False for Overwrite Existing Authentication Agent unless you are sure an authentication agent does not exist on the device. If one is there already, the installation of the Unified Client for Konica Minolta authentication program will fail.

Connection error issues

If the primary DWS server goes offline, a connection error occurs that might not go away when the secondary DWS server goes online. When this happens, log off from the Unified Client for Konica Minolta and then log back on. You need to log out manually when there is a failover, even after the secondary DWS goes online.

Configuring dual-stack IPv6 environments

In a dual-stack environment, use IPv6 addressing or fully qualified domain names with IPv6 DNS entries. Mixing IPv4 device addressing and IPv6 server and endpoint configurations is not recommended. See Dual stack limitations for more information.

Server issues

If a server appears to have gone offline, it may be caused by a certificate error or an expired certificate. Check for the following errors in the Neuf log:

  • An "Unexpected server certificate" error indicates that the server certificate has been changed. If the change is not expected, research the cause of the change. If this change is expected, re-pin the certificate as follows:

    1. Run DWS Web Admin.

    2. Click the Security tab.

    3. Scroll to the Security Certificates section on the bottom.

    4. In the row with the changed server certificate, click the Re-pin link.

  • A "Cannot build trust manager without server certificate" error indicates that the device was configured in DRS to use TTL, but the server is not presenting a certificate. In AutoStore, make sure Use SSL is selected.

Scan issues

If a scan job fails to complete, it may be caused by a server failover as follows:

  • Scanned documents sent by Unified Client for Konica Minolta are not automatically sent to the replacement database.

  • Any in-flight scan or print jobs or inputted metadata when a failover occurs may not be preserved.

  • Scan jobs in progress on the secondary server may be lost when the primary server comes back online.

If this occurs, resend the scan job.

Print release issues

If you are unable to release a document in A4 or US Letter, make sure A4/A3<->LTR/LGR Auto Switch is set to On. See Page size release for instructions.

Search issues

If you get a "Error during prompt processing" error when performing a search from a List or Lookup List field, the ODBC data source needs to be properly configured. Check the configuration of the ODBC data source used for the lookup.
