Contemplating buying a used Brother 2710DW Printer

I watched your 17-sec clip. I’m hearing short bursts of light “tick/ratchet” sounds—first around 6.1–7.6 s, then again ~9.3–15.4 s. It’s not a steady fan whine; it’s intermittent clicks as something turns briefly.
Most likely culprits (for this Brother MFC-L2710DW-series)

    Toner/Drum gear slipping or chipped
    – Happens during brief self-spins even when idle.
    – Fix: swap the toner (TN-730/760) or drum (DR-730). Easy, $40–$90.

    Fuser drive idler/gear pack wearing out
    – Clicks in short bursts when the main motor jogs.
    – Fix: replace fuser or gear (~$60–$120 parts, more work).

    Rear cooling fan lightly rubbing a wire/grille (less likely given the bursty pattern)
    – Would be a steadier buzz/rub that changes with a tap/tilt.
    – Fix: reposition/replace fan ($10–$20).

60-second isolation (no tools)

    A. Remove the drum+toner, close the front door, power on.
    If the clicking disappears → it’s in the toner/drum. Replace that assembly.

    B. Put drum+toner back, power on, then gently press on the rear-right grille (fan area).
    If the sound changes or stops → it’s the fan.

    C. During a single print, listen from the back left (fuser/drive).
    If clicks sync with paper movement or brief motor jogs → fuser/drive gears.

Buy/repair advice

    If it’s toner/drum or fan, that’s cheap/easy → fair price at $60–$85 is fine.

    If it’s fuser/drive gears, expect parts and time; I’d cap my offer at $40–$60 unless the page count is low and prints are perfect.

If you want, print one test page and send a 10-sec clip focused on the back-left corner; I can pinpoint it further and tell you exactly which part to order.

I bought the Brother MFC-L2710DW printer. I need to set it up as an ethernet connected  network printer. Can you help? I have a Asus AX RT 1800s router

Absolutely—let’s wire it up and make it show up on your network.
1) Hook up & get the IP

    Plug the printer’s Ethernet into a LAN port on the ASUS.

    On the printer: Menu → Print Reports → Network Config (or All Settings → Print Reports).
    Note the IPv4 address it prints (it’ll be something like 192.168.50.xx).
    If it shows 0.0.0.0, wait 30s and print again.

(If the printer was used before and acts weird: All Settings → Network → Network Reset → Yes. It will reboot and grab DHCP fresh.)
2) Reserve a fixed IP on your ASUS (recommended)

    Go to router.asus.com (or 192.168.50.1) → log in.

    Advanced Settings → LAN → DHCP Server.

    Under “Manually assign IP”, pick the Brother from the client list, or paste its MAC from the Network Config page.

    Assign something outside the dynamic range, e.g. 192.168.50.45 → Add → Apply.

    Power-cycle the printer or wait ~1 minute so it renews to the new address.

Tip: with Ethernet, you can turn Wi-Fi off on the printer so there’s only one interface:
All Settings → Network → WLAN → Off (leave Wired LAN: On).
3) Optional: check the printer’s web page

Open http://192.168.50.45 in a browser.

    Confirm LPD/RAW/IPP printing protocols are enabled (they usually are by default).

    If asked for a password, use the one on the label (newer Brothers show the default admin password on the back/inside label).

Add the printer on your computer
Ubuntu / Linux (what you’re using)

Quick GUI

    Settings → Printers → Add Printer.

    It often appears automatically. If not, choose Network Printer → Find Network Printer, enter 192.168.50.45.

    Pick connection AppSocket/HP JetDirect (URI will be socket://192.168.50.45:9100).

    Driver: choose Brother MFC-L2710DW (the brlaser driver works well) or IPP Everywhere/AirPrint if offered.

    Print a test page.

CLI (optional)

sudo apt update
sudo apt install cups printer-driver-brlaser sane-airscan simple-scan
sudo usermod -aG lpadmin $USER   # log out/in once if needed
# Try IPP Everywhere first:
sudo lpadmin -p Brother2710 -E -v socket://192.168.50.45:9100 -m everywhere
# If “everywhere” isn’t available/ideal, add via GUI and pick the brlaser model.

Scanning on Linux

    With sane-airscan installed, Document Scanner (Simple Scan) should auto-find the device over the network (AirScan/eSCL).

    If it doesn’t, we can use Brother’s brscan4 package; I can give exact commands if needed.

Windows 10/11

    Settings → Bluetooth & devices → Printers & scanners → Add device → Add manually.

    Add a printer using a TCP/IP address → Address: 192.168.50.45 → Next.

    When asked for a driver, either:

        Choose Brother and pick MFC-L2710DW (or L2700 series), or

        Install Brother’s “Full Driver & Software Package” first, then repeat Add.

macOS

    System Settings → Printers & Scanners → Add Printer.

    IP tab → Address: 192.168.50.45 → Protocol: AirPrint (or IPP).

    Name it and Add → test print.

Quick checks / troubleshooting

    Can’t find it? From your PC: ping 192.168.50.45. If no reply, recheck the DHCP reservation and cable/port LEDs.

    Still shows the old IP? On printer: All Settings → Network → TCP/IP → IPv4 → Boot Method: Auto (DHCP), then power-cycle.

    Discovery oddities on Linux? Use the socket method (9100) and pick the brlaser driver; it’s the most reliable path.

If you tell me which OS you’ll print from most, I’ll tailor the exact driver/commands (and can generate a one-page cheat sheet).
