I am using a WorkCentre 3345 printer and it appears I have forgotten my login credentials. I tried the admin/ 1111 ones, as well as admin/ serial no, but it doesn't work. Can you please assist? Thank you!
I searched our online knowledge base and found an article that should help you.
How to change the system admin password.
If the above link doesn't work then try the below.
Reset the printer to factory default, this will clear all setting and you will need to re-establish the Wireless or Ethernet connection.
