I’ve got an iMac running Ventura. I also have an Epson 4630 printer which I’ve been using for many years. Today I can no longer print. Printer states Encryption Credentials Expired. I’ve removed the printer and re added it as an AirPrint but it hasn’t fixed it. Any ideas how to fix this?
iMac 24″, macOS 13.0
Good morning,
I would check out EpsonNet Config Utility. The printer needs to generate a new certificate. HP and Canon use a web interface to go through the steps. I just finished doing this with my Canon photo printer. I don't have an Epson so I can't be more specific.
UPDATE:
just found this in another request:

This error occurs when the Printer's web certificate has expired.
For me, to resolve this problem, I had to go to the printer's web interface, typically using https://<your_printer_name>.local/ and from there, you go to the following menu option:
Network Security Settings -> SSL/TLS -> Certificate.
From there, you choose the "Update" button form the "Self-signed Certificate" section.
This will have you go through the generation of a new self-signed certificate for your printer's web GUI which is also what Apple uses as it goes over HTTPS when communicating with your printer. I left the "10 year" suggested value for the "Certificate Validity (year)" field, this way I don't run into this problem for quite a long time.
Following that certificate update, I removed and re-added the printer from the Apple settings, didn't need to go through any of the Epson utilities.
I hope this helps!
best of luck.
I am having the same problem. I updated my driver - it printed the test sheet and 1 document then I got the error again. Did you find a solution?
The update certificate solution above from

was the one that worked for me on MacOS Monterey 12.6.2 and my EPSON WF-5620 printer
I hate to use the cliché "not all heroes wear capes" but cl8rqtpi, you saved me hours of frustration. Thanks! Yours was the only solution that worked.
This was very helpful thank you.
Thanks! This is the only thing that worked for me after about 4 hours of trying everything else.
Tried all the others and this was the only thing that cleared the error.
Same issue - reset printers, re-added... I can add it, but then when I go to print, the printer pauses and gives the error: Encryption credentials have expired.
Many thanks to cl8rqtpi & Indrn31 for the fix and detailed explanation of how to navigate it. This is the only thing that finally worked for us!
I have the Epson WF-9610 Series printer. I tried your answer to the encryption credentials expired issue and it didn’t work. Any other suggestions?
Done what was suggested above. Now it is saying Ink/toner is empty. Help.

Is it empty as shown on the printer display or the printer’s embedded web page?
Thank you for your answer. I followed the steps you suggest but when I got to the last step ' select AirPrint' there was no option? Just Auto or other? clicked on Auto and still have same problem:(
Thank you so much for this!!! This fixed it for me!
