Control Codes

It is up to the end user of the Epic 880TM 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 880TM’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.
