DC3 - DC4(sx) - Backup and Restore Procedure

This procedure describes how to make a backup of all parameters stored in the printer.
The backup can be used to send to a (Summa) service engineer for examination, or can be used
to revert to a known configuration of the printer.
It is advised to create a backup when installing the machine for the first time and store this data
on a safe place. After fine-tuning the printer for the different jobs to be done, you can make
another backup.
