Getting error 0xd0620230. Could you help

I managed to track down some information that may be able to help you. Power off your printer, then press &hold buttons while powering on. If it doesnt reset then unplug it & press & hold buttons while plugging it in.
# & 3 Partial reset
# & 6 Semi full reset
# & 9 Full reset
A full reset will clear any stored information in th printer, speed dials ect. So always start with a partial reset and work your way up.
I hope this helps.
