Printer showing a security certificate error
A printer's security certificate is either expired or hasn't been set up correctly. You can ignore the warning and click through to access the printer. It doesn't mean someone is hacking you. If the error blocks printing, log into the printer's settings and update or disable the certificate setting.
Network printers use security certificates to protect their settings pages, just like websites use them. When the certificate expires or was never set up, the browser gives you a warning. You can safely click through the warning to access the printer. The error won't spread to your company network. It's just the printer's own settings that are affected.
- ✓Have the printer's IP address ready — you can find it from the error message or a sticker on the printer
- ✓Know the printer's default admin credentials if needed — check the user manual
- ✓Have a test document ready to print to verify the fix

Skip, I just want a technicianCommon mistakes to avoid
- Thinking the certificate error means your printer or network is being hacked. It's not, it's just an expired certificate
- Not realizing you can click through the warning to access the printer
- Trying to install new certificates without having the right files or knowledge. Disabling the certificate is simpler
- Not checking the printer's internal date. It's set wrong from the factory
Signs you need professional help
- If you can't find the printer's IP address or web settings page, disabling the certificate breaks something else on the printer, or the printer still won't print after disabling the certificate warning, get in touch and we'll help you configure it correctly.
