At the printer just go to Machine Status > Tools > Setup > Add Address Book entry
Click the entry you want to delete and choose Create /Delete
Of course you need to be logged in as the admin to do so.
I did a little looking on this board for my solution, couldnt find anything that helped me as of yet. I am trying to remove 4 email addresses from my copier. I entered the IP, got the work centre screen, but I cant find where to edit the email accounts stored on the machine.
Any assistance is appreciated.
