You need to reset your Brother HL-L2350DW. Maybe it dropped off the network, the toner light won't shut off after a fresh TN-730, or you're handing the printer off to someone else. This 2018 mono laser has a simple one-line LCD and four arrow keys for navigation, so the reset menu is straightforward once you know where to look.
The printer gives you three different resets: network-only, all settings (keeps WiFi), and a full factory wipe. Picking the wrong one wastes time, but each has a clear purpose. Here is how they work and when to use each.
Network Reset When the Printer Goes Offline
This is the one you want if the HL-L2350DW shows as offline in your computer's printer list, won't reconnect after a router swap, or is stuck broadcasting its old SSID. It clears WiFi credentials and resets the wireless adapter without touching anything else.
Press Menu on the front panel. Use the arrow keys to scroll to Network and press OK. Scroll again to Network Reset and press OK. The display asks you to confirm, press the up arrow to select Yes and then OK.
The printer reboots on its own, about 30 seconds. After it comes back, the WiFi LED stays solid (no connection yet). You can reconfigure WiFi through Brother Mobile Connect or WPS push-button pairing.
All Settings Reset (Keep Your WiFi)
If menu options are acting weird, the printer rejects a toner cartridge you know is genuine, or you just want to clear every customization without re-entering your WiFi password, use the All Settings reset. It returns paper size, sleep timer, language, and all other settings to defaults while preserving the wireless config.
Press Menu and navigate to Initial Setup with the arrow keys. Press OK. Find Reset, press OK, then scroll to All Settings and press OK. Confirm with the up arrow for Yes, then press OK again. The printer prompts you to reboot, press 1 on the keypad to confirm.
After the reboot (about 30 seconds), every menu option is back to default, but your WiFi remains active. You won't need to re-pair any devices.
Factory Reset When You Want a Clean Slate
Selling the printer, donating it, or just want to wipe everything including hidden counters? Factory reset does the whole job. It clears WiFi, all custom settings, page counters, and saved configurations. The printer will behave like it's fresh out of the box.
Press Menu > Initial Setup > Reset > Factory Reset and confirm with Yes. The display warns you that everything will be lost. Confirm again to proceed.
After the reboot, the initial setup wizard runs automatically. You will need to choose language and paper size, then set up WiFi from scratch via Brother Mobile Connect.
Hardware Reset If the Screen Is Frozen
If the one-line LCD stays blank, stuck, or unresponsive, the menu path won't work. Brother includes a button-hold hardware reset for this case. Turn the printer off completely. Press and hold the Go button, then while holding it, press the power button to turn the printer back on. Keep holding Go as the LEDs cycle through Toner, Drum, and Paper. Release as soon as that cycle finishes.
The printer reboots into a recovered state with default network settings. Once the LCD comes back, re-pair WiFi through Brother Mobile Connect or WPS.
Reset the Toner Counter After a New Cartridge
A blinking Toner LED after installing a fresh TN-730 or TN-760 high-yield cartridge means the printer thinks the old cartridge is still inside. The counter needs to be manually reset. Open the front cover. With the cover open, press and hold the Go button until all four LEDs (Toner, Drum, Paper, Ready) light up at the same time, then release. The display will show Replace Toner. Press the up arrow once to select Reset, then press OK. Close the cover.
The toner light shuts off. Print a test page to verify the printer recognizes the new cartridge. The HL-L2350DW uses standard TN-730 (~1,200 pages) or high-yield TN-760 (~3,000 pages), and the reset procedure is the same for both.
Set Up WiFi After a Reset
After any reset that clears network settings, you need to pair the printer to your WiFi again. The HL-L2350DW runs on 2.4 GHz only, so make sure your router broadcasts a 2.4 GHz band. Open Brother Mobile Connect on your phone (iOS 14+ or Android 9+). Tap Add Device and follow the prompts, the app detects the printer in setup mode and handles the rest.
You can also use WPS push-button pairing. On the printer, navigate Menu > Network > WLAN > WPS and press OK. Within two minutes, press the WPS button on your router. The printer joins the network without needing the password.
If you are on a mesh network and pairing fails, the HL-L2350DW's older radio sometimes cannot handle WPA3 with PMF required. Switching to WPA2/WPA3 transitional on your router usually clears that up.
Re-Add the Printer on Your Computer
If you reset the network, your computer still thinks the printer is at the old IP address. Open Settings > Bluetooth & devices > Printers & scanners on Windows (or System Settings > Printers & Scanners on Mac). Remove the existing HL-L2350DW entry. Then click Add device and let it rediscover the printer. The fresh entry picks up the printer's new IP after the reset. This also clears any stale driver cache that might cause phantom paper jams or off-queue errors.
