User manual SHARP AR-FR24U

[. . . ] As soon as each job in copy mode, printer mode, network scanner mode and fax mode* is finished, the security function erases the document image data that was generated and stored in memory for the job. * The document image data that is generated for jobs in fax mode is encrypted and then erased from memory as soon as the job is finished. To ensure that the data security function of the machine provides maximum security, observe the following: The key operator plays an important role in maintaining security. Exercise appropriate care in selecting the person that will assume the job of key operator. [. . . ] If the job is large and more than 6*2 seconds is required to clear the data, the following progress bar appears: The fax data is not held in Flash memory and thus there is no need to clear it. *2 The duration of the message display can be changed with the key operator program, "MESSAGE TIME SETTING". Printing a normal print job in printer mode, the image data is automatically cleared from memory after printing is completed. However, when the job retention function is used (see the online manual for network printer), the image data is retained in memory. The retained image data can be cleared by selecting the hold data and then touching the [DELETE] key. The machine power is turned off while image data is being cleared from memory or before a job is finished, the data may not be completely cleared. If you wish to prevent this from happening, use "CLEAR ALL MEMORY" in the key operator programs (page 4 of this manual) to completely clear all data before turning off the power. This section explains the key operator programs in the unit that are related to the security function. For the procedure for using the key operator programs, see the KEY OPERATOR'S GUIDE. Key Operator Code Change This program is used to change the key operator code. The key operator is required to change the key operator code from the factory default to a new user selected code. Under no circumstances should the Key Operator use the default "Key Operator Code". The key operator is responsible for changing the Key Operator Code to a new code at least every 60 days. When the data security kit is installed, settings related to security (with the exception of [SSL SETTINGS]) are added to the settings that appear when the [SECURITY SETTINGS] key is touched. Detailed procedures for using these settings can be found on the following page. Use this setting when you wish to manually clear data stored in the unit's memory. This function is executed, unprocessed data in the unit will also be cleared. Recommend that you execute this program before turning off the power. The optional fax expansion kit is installed, remote fax reception (fax reception activated from an extension phone connected to the machine) will not be possible while data is being cleared. However, the extension phone can still be used at this time to make a call. The following screen appears to confirm your selection. Return to the "SECURITY SETTINGS" screen, touch the [NO] key. [. . . ] You enter the wrong number A message appears telling you to check the product key again. The entered number is correct A message appears telling you that the power must be turned off and then on again. After checking the message, touch the [OK] key. The security function is enabled when you turn on the power again. [. . . ]
