HP Designjet Printer Series Security Settings 3.18 Printer Access control For some printers, when setting an Embedded Web Server admin password you are also preventing access to certain front panel features. The features protected in the front panel are: • Network connectivity (including also Internet connectivity and Diagnostics&troubleshooting of the network connectivity) • Control firmware upgrades • Setup • Reset factory defaults • External hard disk connection • Security If a user loses the admin password, it is not possible to reset it so the printer would be locked. There is a service menu option to reset the admin password. 3.19 External hard disk (EHD) Some printers allow the connection of an external hard disk. Any HP Designjet printer with an internal hard disk uses is for four main purposes: • Store the printer's firmware & resources (media profiles, demo plots, diagnostic plots). • Virtual memory for job processing. • Job storage/queue • Storage for printer's accounting data. The HP Designjet External Hard Disk was designed to fulfill one specific use for those security conscious customers that want to preserve the confidentiality of the jobs being printed in their HP Designjet printers. How the system works 1. Connect the External Hard Disk (EHD) into the printer's USB host port. 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 5220.22M). 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 24
