Disposal of HDD Units 
ƒ  Never remove an HDD unit from the work site without the consent of the client. 
ƒ  If the customer has any concerns about the security of any information on the HDD, 
the HDD must remain with the customer for disposal or safe keeping. 
ƒ  The HDD may contain proprietary or classified (Confidential, Secret) information. 
Specifically, the HDD contains document server documents and data stored in 
temporary files created automatically during copy job sorting and jam recovery. Such 
data is stored on the HDD in a special format so it cannot normally be read but can be 
recovered with illegal methods. 
Reinstallation 
Explain to the customer that the following information stored on the HDD is lost when the 
HDD is replaced: 
ƒ  Document server documents 
ƒ Custom-made stamps 
ƒ  Document server address book 
The address book and document server documents (if needed) must be input again.   
If the customer is using the Data Overwrite Security feature, the DOS function must be set 
up again. For more, see Section 1 (Installation). 
If the customer is using the optional Browser Unit, this unit must be installed again. For 
more, see Section 1 (Installation).
