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

• All menu settings to factory default values
• Factory settings, such as formatter number, page counts, and
factory paper settings

O until the Attention,
Ready, and Go lights turn on.

The device lights cycle from front to rear. The NVRAM initialization
runs until completion, when the device is in the Ready state.
