T520 wireless feature locked by admin

[TKDev]

I purchased a used T520 36in and the message I get is "this feature has been locked by your system administrator or the person who set up the printer." when trying to access wireless features. I have tried everything from soft resets to hard resets and even using the EWS to reset the passwords. Even in the EWS, when I select the option to enable wireless in administrator settings, it says successful, but its still locked on the printer. Any help will be greatly appreciated.

The below is all know about your Deskjet: 520.  Hope I am not oversharing!

The manual listed below shows how to reset on page 103.   If that does not work then you need to take it in for service.

Watch the reset video or perform the steps. After resetting, you generally have 2 hours to complete the setup. Decide if you want to connect the printer to the router or to print directly to the printer and bypass the router.

Many HP and other OEM printers have problems with the router when the router has two or more bands and all have the same name (SSID). Log into the modem and rename one of the bands. Alternately, contact your ISP and have them rename a band, or simply use Wi-Fi direct.

HP+ printers are designated by a lowercase "e" at the end of their model number (e.g., 8135e rather than 8135). These models are enabled for HP's smart printing ecosystem, which requires a permanent internet connection, an HP account, and the exclusive use of Original HP ink for the lifetime of the printer.

Disconnecting the USB cable may still leave the printer in the wired or Wi-Fi mode. Connecting an ethernet cable may still leave the printer in Wi-Fi mode. The Wi-Fi reset is used to put Wi-Fi printers into setup mode. Some resets are simple and others require a video to understand. Factory resets cannot be revealed in this forum. To do a factory reset of your printer, you must contact HP.

Wi-Fi reset instructions and videos (if any) are shown below. Generally you have 2 hours to connect your printer after performing the Wi-Fi reset. Note that a reset video may show a slightly different model than yours. Do not call any phone numbers revealed in any video or site.

The steps below are Wi-Fi only and do not perform a factory reset.

Wi-Fi connection

Spoiler

Ideally, your Wi-Fi printer should connect to the modem or router. If your network has multiple boosters / repeaters, it is possible the printer may connect randomly to any of the units. The router needs to provide the same IP address on every connection. This rarely happens with random connects. An alternate Wi-Fi connection is Wi-Fi direct. Your laptop or smartphone prints directly to the printer and does not go through the router. Do not call any phone number revealed in any video or site.
