Selecting the device certificate
Select the device certificate to be used for S/MIME using a web browser from networked computers. (We use Web Image Monitor installed on this machine.) If the valid period of the user certificate elapses, no electronic signatures can be attached. Prepare a certificate that is within its valid period.
Open a web browser from a networked computer, and then log in to Web Image Monitor as the network administrator.
For details on how to log in, see Administrator Login Method.
Point to [Device Management], and then click [Configuration].
Click [Device Certificate] under "Security".
Select the certificate to be used for the electronic signature from the drop-down list box in "S/MIME" under "Certification".
Click [OK].
The certificate to be used for the S/MIME electronic signature is set.
“Updating...” appears. Wait for about one or two minutes, and then click [OK].
If the previous screen does not appear again after you click [OK], wait for a while, and then click the web browser's refresh button.
Log out.
