I could only find instructions on how to upgrade the firmware via the web portal, I suggest that you call into the support department at 1-800-835-6100.
i can't log into the printer's web portal
not using the default id / password admin / 1111
or admin / ser# (with either upper or lower case letters)
or after reset through the control panel menu options
the instructions for firmware upgrade are only available by the web portal
how can i run a firmware upgrade without having to log in as administrator
how can i hard reset the printer
