You cannot use the machine while data is being erased from the memory. It may also take some time until the machine becomes ready to scan once the data is completely erased.
The performance of the machine may degrade when processing jobs.
Changes are only effective after you restart the machine (the main power switch is turned Off, and then back On). For instruction on restarting (turning the main power switch Off and then On) the machine, see "Main Power and Energy Saver Key."
