Only perform the following procedure if absolutely necessary. Performing an

NVRAM initialization resets some parameters that cannot be restored later.

NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a
default ROM value, depending on the variable. It also performs a system reset.

NVRAM initialization resets the following:

ł

All menu settings to factory default values

ł

Factory settings such as formatter number, page counts, and factory paper settings

Press and hold down the

Go

 button for at least 20 seconds. During this
