Security - SSL/TLS Server Communication

This page allows you to set security on data sent and received by the printer when the printer uses HTTPS communication.
The data that are subject to security protection are IPP print jobs and information exchanged between the printer and web browsers.
These data will be encrypted using SSL/TLS communication.

This item appears if your printer supports SSL/TLS server communication.
The following settings will become active after rebooting the printer from CentreWare Internet Services or manually turning off and on the printer.
Note that the data in the memory are cleared when the printer is turned off.

To access CentreWare Internet Services when data encryption is enabled, enter "https" before its address instead of "http".
Example of IP Address:
https://192.168.1.100/
Example of Internet Address:
https://xxx.yyy.zz.vvv/

SSL/TLS Server Communication
Select the [Enabled] check box if enabling SSL/TLS server communication.
If you do not have a certificate, "Disabled" is displayed. In such case, click [Generate Self-Signed Certificate] and create a certificate.

SSL/TLS Server Communication Port Number
Enter the port number that will accept requests from your web browser. The port number must be 443 or any number between 8000 and 9999. The default is 443.
If you changed the port number, enter a colon (:) and then the port number after the printer address when accessing CentreWare Internet Services.
http://Printer_Address:Port_Number/
Do not use the same number as the Port9100/IPP/WSD/HTTP port number.
WSD stands for Web Services on Devices.

Generate Self-Signed Certificate
Click the [Generate Self-Signed Certificate] button to create a certificate. When clicked, [Create New Certificate] page appears.
This item does not appear if a certificate is already created.

Certificate Management
Click the [Certificate Management] button to verify or delete the contents of the certificate. When clicked, [Certificate Management] page appears.

Security - Create New Certificate

Set the following items to create a certificate.
Note that the data in the memory are cleared when the printer is turned off.

Public Key Method
Select the method of the public key from [RSA/SHA-1] and [RSA/SHA-256]. If you want to enhance security, select [RSA/SHA-256].
This setting becomes active after rebooting the printer from CentreWare Internet Services or manually turning off and on the printer.

Public Key Size
Select the size of the public key from [512 bits], [1024 bits] and [2048 bits]. If you want to enhance security, select [2048 bits].
This setting becomes active after rebooting the printer from CentreWare Internet Services or manually turning off and on the printer.

Issuer
Displays the issuer of the certificate. The issuer will be assigned automatically based on the printer name and MAC address. You cannot change the issuer once assigned.

Validity
Set the validity period of new certificate. The validity period can be set within the range of 1 to 9999 days.

[Generate Signed Certificate] button
Transfers the settings to the printer and creates the certificate.
It may take several seconds for the certificate to be created. Do not click [Generate Signed Certificate] button more than once.

[Back] button
Takes you back to the [SSL/TLS Server Communication] page without transferring the settings to the printer.

[Delete] button
Click this to delete the certificate currently displayed on the window.
This setting will become active after rebooting the printer from CentreWare Internet Services or manually turning off and on the printer.

If you remove a previously-used network expansion card from one printer and install it in another printer, the certificate created on the previous printer is deleted. The SSL/TLS server communication setting becomes invalid too. After installing the network expansion card in another printer, you will need to create a certificate on that printer.

It may take several seconds for the certificate to be deleted. Do not click [Delete] button more than once.
