Appendix 69 Management Function access control What it does Firmware Updates This controls the ability to update firmware from any source other than a flash drive. Firmware files that are received through FTP, the Embedded Web Server, etc., will be ignored (flushed) when this function is protected. Operator Panel Lock This protects access to the locking function of the printer control panel. If this is enabled, then users with appropriate credentials can lock and unlock the printer touch screen. In a locked state, the touch screen displays only the "Unlock Device" icon, and no further operations can be performed at the device until appropriate credentials are entered. Once unlocked, the touch screen will remain in an unlocked state even if the user logs out of the device. To enable the control panel lock, the user must select the "Lock Device" icon, and then enter the appropriate credentials. PJL Device Setting Changes When disabled, all device settings changes requested by incoming print jobs are ignored. Remote Management This controls access to printer settings and functions by remote management tools such as MarkVisionTM. When protected, no printer configuration settings can be altered except through a secured communication channel (such as that provided by a properly configured installation of MarkVision). Apps Configuration This controls access to the configuration of any installed applications. Web Import/Export Settings This controls the ability to import and export printer settings files (UCF files) from the Embedded Web Server. Configuration Files Import/Export This controls the ability to import and export settings and security configuration files. Internet Printing Protocol (IPP) This controls the ability to use the IPP. Function Access Function access control Address Book Cancel Jobs at the Device What it does This controls the ability to perform address book searches in the Scan to Fax and Scan to E‑mail functions. This controls the ability to cancel jobs from the printer control panel. Change Language from Home Screen This controls access to the Change Language feature from the printer control panel. Color Dropout This controls the ability to use the Color Dropout feature for scan and copy functions. Copy Color Printing This controls the ability to perform color copy functions. Users who are denied will have their copy jobs printed in black and white. Copy Function This controls the ability to use the Copy function. Create Bookmarks at the Device This controls the ability to create new bookmarks from the printer control panel. Create Bookmarks Remotely This controls the ability to create new bookmarks from the Bookmark Setup section of the Settings menu on the Embedded Web Server. Create Profiles E‑mail Function This controls the ability to create new profiles. This controls access to the Scan to E‑mail function.
