I am also unable to authenticate as admin. I see on documentation mentioning the capitalization of serial number is important, but the serial number is only a number on my device? I even tried entering the whole line:
"Serial Number.: xxxxxxxxx". Am I looking at the right thing ? Also, anyone found any way to hard-reset the printer ?
I have entered the serial number, making sure to use indicated case. I've tried 3 times. I get a message: Invalid characters for admin password
I ran into the same issue today on my B210. For me the problem was that the password I initially set was too long (>32 characters) but the interface didn't verify the input. When truncating the password to the first 32 characters I was able to login again.
Just got off the phone with Xerox support. The password can be reset by unplugging the machine for 5 minutes and then reinstalling it from scratch on your computer. It has to be at least 5 minutes! Once you run through the setup process and access your printer's admin webpage you should see a note that says that the printer password has reverted to the default and be given the option to reset it. Apparently, this doesn't work all the time, but it worked for me. Good luck!
If the printer had worked and you forgot the password, call Xerox. You may end up having to get a replacent printer if it's under warranty (within one year, I believe).
If the printer never worked with a Mac, call the apple help line. They will walk you through the fix (pretty easy). Also, check the Apple support forum. They might have the steps listed.
Centre Ware Internet Services (B215 on Catalina) will not accept my new password. I'm advised to factory reset network settings to resolve. I cannot do this in CWIS as the password will not work. I cannot do it using Easy Printer Manager as it is not supported in Catalina. How can I do this?
To others reading this case please remember the password may be case specific on your printer. Make sure you enter the Serial number with the capitalization when trying the serial number as the default password.
I ended up returning the printer for a new one. Doesn't seem like the most cost-effective solution.
thank you Zerox! Seriously, great treatement
