2. The printer will detect the EHD and will ask the customer for permission to install it. When the customer
accepts, the printer will perform the following step:
3. A copy will be made of all the customer’s information that is stored in the internal HD and copied to the
external HD.
4. The customer’s internal HD partition will be deleted after a highly secure erasing process (DoD 5220.22-M
).
5. The printer will be configured to use the EHD as the repository for ALL customer jobs (including the temporary
processing storage area).
6. Once the EHD has being installed, all the customer jobs will ALWAYS be stored in the EHD
7. When the printer is switched off, as a security measure, the EHD can be removed and kept in a secure location.
Notes:
• Once the printer has an EHD installed it can no longer be initialized without it.
• If for any reason the installed EHD is no longer available (the customer loses the EHD, or the EHD is broken),
there is a mechanism (through a special bootmode controlled with an specific front panel key combination)
that reconfigures the printer to work without the EHD. However in that particular case, all the information
stored in the EHD is lost.
• Once the EHD is installed on a particular printer, it becomes fully tied to it. It is not possible to move this EHD
to another HP Designjet printer without losing the stored information. When the printer detects an EHD that
has been installed on a different printer, it will advise the customer about it. If the customer decides to go
ahead and use the EHD on a different printer, the printer will erase the contents of the EHD (once again, using
the highly secure DoD 5220.22-M
process)
• The EHD has its own software based encryption mechanism that prevents anyone reading the contents of the
EHD, for instance, by plugging it into a PC. The encryption system is not a standard one and cannot be
considered as an extremely secure encryption mechanism (such as the standard encryption system DES
, RSA,
FIPS 140
…), but it does add a level of security that makes it difficult when trying to read the contents by just
connecting the disk to a PC.
The EHD is not intended to be used as an USB memory stick, that is, to copy documents from a PC, plug it into the
printer and to print them.
