jobs can be overwritten by Auto Erase Memory only if they have been deleted in advance.

on the hard disk, so it will not be overwritten by Auto Erase Memory.

Erase All Memory
This can be specified by the machine administrator.
You can erase all the data on the hard disk by writing over it. This is useful if you relocate or dispose of
your machine.
• If you select "Erase All Memory", the following are also deleted: user codes, counters under each
user code, user stamps, data stored in the Address Book, printer fonts downloaded by users,
applications using Embedded Software Architecture, SSL server certificates, and the machine's
network settings.
• If the main power switch is turned to [Off] before Auto Erase Memory is completed, overwriting will
be stopped and data will be left on the hard disk.
• Do not stop the overwrite mid-process. Doing so will damage the hard disk.
• Should the main power switch be turned to [Off] before Auto Erase Memory is completed, overwriting
will continue once the main power switch is turned back to [On].
