■ Backing up and clearing data stored with the print hold
function
When the data security kit is installed, data previously stored in the machine with the
print hold function is cleared. For this reason, any data that you need to keep is copied to
a computer before the data security kit is installed, and then returned to the machine
after installation and clearing of the previous data. (This work is normally performed at
the time of installation of the data security kit.)
Only confidential files can be used to return data from a computer to the machine after
installation of the data security kit. For the procedure for storing data on a computer and
returning data from a computer to the machine, see help in the Web pages of the
machine.
