Control Panel Methods
There are several Control Panel configurations that support configuring the Remote Firmware Upgrade settings.
Products with a color touch screen, two line LCD display or graphical LCD
ON – allows a firmware update to be downloaded to the printer
OFF – refuses firmware updates (can be changed to ON from within the firmware update utility)
OFF AND LOCKED – refuses firmware updates (can only be changed to ON from the product control panel)
Press the Cancel button for 10 seconds to enter the RFU enable/disable mode.
(The printer flashes the Ready, Attention, and Go LED’s.)
(The remaining 3 LEDs indicate the current RFU state.)
Press the Go button to cycle through the 4 possible RFU states. Pressing the Go button will cause the printer to move to the next state. The below LEDs signal the current state:
If the Paper Out LED is illuminated, RFU is enabled.
If the Toner Low LED is illuminated, RFU is disabled.
If none of the above LEDs are illuminated, the printer is in cancel mode.
Exiting RFU enable/disable will return the printer to its previously saved configuration.

HP LaserJet Printers and Multifunction Devices - How to Disable Remote Firmware Upgrades
The firmware upgrade operation updates or replaces device operating system code on HP printers and multi-function devices, and is commonly referred to as a “remote firmware update” (RFU). The Remote Firmware Upgrade setting determines if the firmware update process is allowed to be performed.
Device List
The following devices support the stated RFU disable options:
Updating the RFU Setting
There are multiple methods to configure the RFU option. The setting can be configured for multiple devices simultaneously using the HP Web Jetadmin (WJA) fleet management tool. Devices can also be configured individually through a web page, however some older HP Printers require HP Web Jetadmin. Some low-end printers manipulate the setting from the control panel menu.
HP Web Jetadmin Method
Expand Security section and select Printer Firmware Update .
Select the Checkbox and select the Disable radio button.

Embedded Web Server (EWS) Method
Open the EWS configuration interface by entering the device IP address in a web browser.

RFU Update Configuration Best Practices
Performing a Remote Firmware Update (RFU) is typically the responsibility of an administrator within an organization. For security reasons, RFU is an option that should only be enabled when new firmware is being loaded. RFU should be disabled at all other times.

Объясните пожалуйста. Хочу заказать создание сайта для работы. Цена 3600. Но мне нужно оплачивать раз в год 5000. Вот так и не пойму зачем? И неужели, нельзя заплатить один раз и потом им пользоваться.
Nintendo Switch у кого есть эта консоль. Подскажите сколько стоят на неё игры и вообще стоит ли она своих денег?
Приветствую прогрессивных форумчан!
Задача настроить wi-fi сеть в 3-х этажном здании оказалась не так проста для меня, как казалось на первый взгляд, поэтому прошу совета у вас.
Как я понял, мощность wi-fi устройств ограничена законодательно и не превышает 20 dBm, а этого едва хватает что бы пробить стену (на арматуре строители не экономили), WDS-мосты снижают скорость минимум в 2-3 раза, а канал и так очень маленький - всего 10 Мбит/с
Вот думаю, как лучше всё это сделать? В идеале было бы "запитать"… (читать далее)

Naturally, I wondered why a perfectly good printer would get to this state. I power cycled the printer which revealed the true error:
INFLATE FAILURE
DOWNLOAD FILE NOW
SEND RFU UPGRADE
I looked this error on Google, and found many other people in the same situation with no really good answers. This printer either needed a new formatter board or an RFU firmware update. I thought it would be simple enough to connect to the printer via FTP over the network and force the update, but I noticed that there was no activity displaying on the jetdirect port on the side of the printer. Sure enough, a ping to the printer resulted in lost packets.
2. Uncompress the files and remove the old compressed file since that will no longer be needed. Once again, I placed my file on the desktop, so I knew where it was.
6. In the add printer dialog box, make sure that the default icon is selected.
11. This next step involves using the terminal. Open the terminal by going to Applications>Utilities>Terminal. You can also perform a spotlight search for it.
Extra: For you PC users (XP and Vista), the theory of sending the firmware is the same. The main differences is the dos console and how the printer is added to the system.
