Introduction

The Canon imagePROGRAF series is equipped with a disk erase feature that erases print jobs sent to the printer from the printer's hard disk. This feature completely erases data sent to the printer, such as classified data and private information, so that it is not leaked to third parties.

Generally, data written to hard disks on computers or printers is not completely erased when the memory is deleted or initialized in the usual way. You can use data recovery software to recover deleted data and retrieve information. This is precisely why preventing data recovery and completely deleting data is so important.

Disk Erase Features

The disk erase feature included with the Canon imagePROGRAF series responds to the need for an increased level of security.

The disk erase feature included with the Canon imagePROGRAF has the following 3 modes.

Secure Erase Mode

This is the highest level of erasure. It meets to U.S. Department of Defense requirements (DoD 5220-22.M) for the erasure of disk media.

Data stored on the printer's hard disk is overwritten multiple times and then checked after the final overwrite. This makes hard disk analysis used during disk recovery impossible, preventing data recovery. For more information, see "5 How Secure Erasure Mode Works".

Secure Quick Erase Mode

In this mode, data stored on the printer's hard disk is overwritten once with random data. This prevents data from being recovered using software. This mode erases data quicker than Secure Erase Mode.

High-speed Erase Mode

In this mode, the file management information for the data stored on the printer's hard disk is initialized. Because only the file management information is initialized, the data still remains on the hard disk.
