Hi, I was a bit stupid when I was setting up a 6015NI and put in a admin. username ans password. But I didn't realise until it was to later, that there was limits on both, so now I don't know either.
Is there someway I can reset that password and user to factory settings?
You could try the following. However this will reset everything. Print a config sheet before, just so you don't lose your settings:
CAUTION: Modifications to the Reset Defaults settings should be performed by the System Administrator. Incorrect settings may cause the printer to become unavailable.
