Removing Unnecessary Data From The Hard Disk - Canon imagerunner advance C5550i User Manual

Removing Unnecessary Data from the Hard Disk

Copied or scanned image data, as well as document data that is printed from a computer, is temporarily stored on the
hard disk. Although the document data and image data is automatically deleted from the hard disk when operations
are complete, some data remains. You can further improve security by using the hard disk data complete deletion
function to automatically delete any data that remains after operations are complete.
● You cannot use the machine while unnecessary data is being deleted. After data deletion is complete, it may
take some time before the machine is ready to scan originals.
● The machine's processing capacity may decrease when data is deleted.
● Initialize the data and settings to delete data such as files stored in the Mail Box, Address Book information,
or copy and print log information.
