Maintain the printer Follow the onscreen instructions to download the firmware file and store it on your hard disk. Then select the downloaded file and click Update. The firmware includes a set of the most commonly used paper presets. Extra paper presets can be downloaded separately; see Download paper presets on page 37. If you experience very slow progress while uploading the firmware file to the printer, the reason could be that you are using a proxy server. In that case, try bypassing the proxy server and accessing the Embedded Web Server directly. ● In Internet Explorer 6 for Windows, go to Tools > Internet Options > Connections > LAN Settings, and select the Bypass proxy server for local addresses check box. Alternatively, for more precise control, click the Advanced button and add the printer's IP address to the list of exceptions, for which the proxy server is not used. ● In Safari for Mac OS, go to Safari > Preferences > Advanced and click the Proxies: Change Settings button. Add the printer's IP address or its domain name to the list of exceptions, for which the proxy server is not used. Secure disk erase The printer's hard disk is used as a temporary storage area for print jobs. The Secure Disk Erase facility can completely erase your information from the hard disk to protect it from unauthorized access. You can choose to erase particular files, or the whole hard disk. Secure Disk Erase provides three different levels of security: ● Non-Secure Fast Erase: all pointers to the information are erased. The information itself remains on the hard disk until the disk space it occupies is needed for other purposes, and it is then overwritten. While it remains on the disk, it is difficult for most people to access, but may be accessed using software designed for the purpose. This is the normal method in which files are erased on most computer systems; it is the fastest method but the least secure. ● Secure Fast Erase: all pointers to the information are erased, and the information itself is also overwritten with a fixed character pattern. This method is slower than Non-Secure Fast Erase, but more secure. It may still be possible to access fragments of the erased information by using special tools to detect residual magnetic traces. ● Secure Sanitizing Erase: all pointers to the information are erased, and the information itself is repetitively overwritten using an algorithm designed to eliminate any residual traces. This is the slowest method, but the most secure. Secure Sanitizing Erase meets the US Department of Defense 5220-22.m requirements for clearing and sanitization of disk media. This is the default security level when using Secure Disk Erase. Secure Disk Erase is one of the facilities provided by Web JetAdmin, which is HP's free Web-based print management software. See http://www.hp.com/go/webjetadmin/. If you have difficulty in using Secure Disk Erase from Web JetAdmin, please contact HP Support. See HP Customer Care on page 180. NOTE: If you choose to erase the whole hard disk, you may be asked to restart the printer several times during the process, which will take about 6 hours with Secure Disk Erase or 24 hours with Secure Sanitizing Erase.
