It is up to the end user of the Epic 880
TM
to implement and use the level of security
that is required.
CAUTION: If you have initialized the electronic journal and don’t
know the password, there is no way to erase the electronic
journal without returning the printer for service. The warranty
does not cover this. All Epic 880
TM
’s are shipped with the
electronic journal partitioned and erased but not initialized.
Initializing the Electronic Journal
Once the electronic journal is partitioned, it can be initialized. Initializing the electronic
journal sets the password and formats the flash to accept journal entries. Each entry
may be any length up to 8K, and entries greater than 8K are truncated. Entries will be
added to the electronic journal until it is full. If the electronic journal is full, entries will
be lost. The [ENQ]<25> command can be used to query the state of the electronic
journal.
