3.6.3 Specifying the Print Data Deletion Time
The data encrypted with the PKI card is deleted from the PKI Encrypted
Document User Box of the MFP after saved in the User Box and printed on
the MFP.
However, if unprinted print data in the PKI Encrypted Document User Box
exceed the User Box upper limit, new data cannot be saved in the User Box.
To avoid this problem, you can configure the setting to automatically delete
data that remains saved in the User Box for a specific length of time.
