That would depend on where in the world you reside.
In the USA it is 1-800-939-3769, they will need your Serial number and a scan of the printers configuration report (For process reasons, it isn't required to verify your settings in this case)
Your interpretation is spot on, and your method could/should work, but at this time, even in the latest firmware, it isn't an option, the user does not exist to modify.
I spoke to the testing team, they agree on the issue, it should be added. Best bet now is to call them and request it.
To be clear, the testing team doesn't code the firmware, but you go through them to have the request sent up the chain to them. And they can't do that until they get a request from a customer by phone.
Maybe I'm wrong but I would interpret...
"Color job received, user does not have permissions to print color job, then Print Job in Black & White"
... to refer only to a job that is received WITH an account code, but the account has color printing disabled in it's permissions.
I noticed that when IPP Exception mode is turned on, it logs print jobs under the account "IPPExceptionUserID". Would it be possible to add this user and then restrict it to b&w only?
On yours, you would have set it to BW as default in CWIS/EWS, but that only works for Airprint (And is considered a bug that will probably get fixed), but it does not apply to MOPRIA or WiFi Direct, so it isn't a satisfactory answer to what CBHB asked.
Though it appears they may not be a satisfactory answer as mine does not seem to have worked they way it should.
It will only work if XSA is set to track color only, sorry.
Still not able to get the results I want. I enabled the Job Override settings as you suggested, and disabled all exceptions, but using Airprint resulted in an error page about invalid accounting codes. I tried enabling just Guest Mode under exceptions, but this time Airprint resulted in a full color page.
Instead of excluding the IPP jobs you leave them accounted for, and then set an overrideso that if there is no account, it prints BW instead of deleting. Which of course means if you have people you don't want to be able to print at all it won't be a viable option.
