I am unable to access the https pages to update the security certificate.  I am using Chrome browser.  When I get the certificate error, and click the advanced button to go to the page anyway, I get a connection reset error.  The printer is running the latest firmware, 002_2539E.   I have not tried resetting the printer factory settings, because I can't find the administrator pin number label behind the cartridge access door.

Printer? there are several different methods to access the EWS and knowing the model is required to help you out with this.

Yeah the programming asks for that info but does not post it. As for the 479, I believe that the PIN is inside the MP tray door or on the cartridge door and not on the cartridge carriage. I can confirm that tomorrow, but you will want to check there.
