Certificate) and the intermediate Certificate into printer as the same time.
However, printer of this model supports installation of only a single Certificate, intermediate
Certificate cannot be installed in printer. Be sure to install the SSL server Certificate in printer.
When installation of intermediate Certificate is required, install the intermediate Certificate
not in printer, but in client PC (browser).
For the method of installing the intermediate Certificate in client PC (browser), refer to the
following.
Installing the intermediate Certificate (or CA certificate) in client PC (browser).

format: ComodoJapanCA.Crt, and the binary format: ComodoJapanCA.cer.
Either one of these formats can be opened. (Same result can be obtained.)
