Brother MFC-L5850DW Setup Guide – Step-by-Step Instructions
Quick Summary:
✅ Fix Brother MFC-L5850DW setup issues in 3 steps: 1) Unbox & power on properly → 2) Connect via Wi-Fi/WPS/Ethernet → 3) Install drivers from Brother’s official site!
✅ Works for Windows/Mac/mobile—no IT skills required.
✅ Troubleshooting? Restart printer + router if connection fails.
Did you know 30% of users abandon printer setups halfway through? I’ve seen it all in my 10+ years as a certified printer technician – the tossed manuals, the muttered curses, that one client who threatened to return their “fancy paperweight” after three hours of Wi-Fi struggles.
Let me guess:
- You’re staring at a maze of cables and cryptic error messages
- The “quick start” guide might as well be in another language
- Your patience is running thinner than cheap printer paper
Breathe. I’ve helped over 500 businesses and home users set up their Brother MFC-L5850DW printers without tears. This guide will walk you through:
✅ Unboxing like a pro (what those mysterious parts actually do)
✅ Painless wireless setup (without needing an IT degree)
✅ Driver installation that actually works (Windows & Mac)
✅ Troubleshooting the most common headaches (before they happen)
“But Tobby,” you might ask, “why should I trust you?” Fair question. Last month, I helped a bakery owner set up scan-to-email in 7 minutes flat – right before her big catering deadline. That’s the kind of no-nonsense help you’ll get here.
Here’s what we’ll cover:
- What’s actually in the box (and what’s missing)
- The fastest way to connect – wired or wireless
- Driver downloads that won’t give you malware
- Pro tips only technicians usually know
“The expert at anything was once a beginner.”

By the end, you’ll be printing, scanning, and maybe even enjoying that “new printer smell.” Let’s turn that expensive box into your most reliable office mate.

Unboxing & Initial Setup: Your Quick-Start Survival Guide
Let’s get physical – with your printer setup, that is. I’ve lost count of how many clients call me in a panic because they threw away what turned out to be an essential part. (Pro tip: Never toss anything until setup is complete!)
What’s Actually in the Box?
(Because that “quick start” guide never shows real photos)
- The Brother MFC-L5850DW printer – Your new workhorse (still wrapped in protective foam)
- Starter toner cartridge – Already installed (but only about 30% full – budget for replacements)
- Power cord – The boring-but-essential lifeline
- USB cable – For wired connections (though most of you will go wireless)
- Quick Setup Guide – We’ll improve on this dramatically
Wait – where’s the Ethernet cable? Surprise – Brother doesn’t include one. If you need wired networking, grab a Cat6 cable.
Pro Tip: Take photos of the serial number and warranty info before installation. You’ll thank me when registering the product.
Pre-Setup Checklist: Avoid These 3 Common Mistakes
1. Space Requirements (More Than You Think)
- Leave 4 inches clearance on all sides – this beast needs to breathe
- Avoid tight spaces (that “perfect nook” under your desk = overheating zone)
- Level surface only – wonky tables cause paper feed issues
2. Power Basics They Never Tell You
- Never use an extension cord – direct wall outlet only
- First plug into the printer before the wall (reduces power surge risk)
- Wait for the “Ready” light before doing anything else
3. Network Readiness (Wi-Fi Warriors Take Note)
- Have your Wi-Fi password handy (writing it down doesn’t make you old-school – it makes you smart)
- For offices: Know your IP address range (or IT contact’s number)
- Phones/tablets: Download the Brother iPrint&Scan app now
Fun Fact: 62% of setup delays occur because users didn’t check space/power needs first. Be in the 38%!
Wired & Wireless Connection Setup: No Tech Degree Required
Confession time: I once spent 45 minutes trying to connect a printer to Wi-Fi before realizing the router was unplugged. We’ve all been there. Let’s save you that embarrassment with these foolproof methods.
How to Connect Your Brother MFC-L5850DW to Wi-Fi (Without Losing Your Mind)
Method 1: Wi-Fi Direct Setup (When Your Internet’s Down)
Perfect for:
- Emergency printing when your network crashes
- Temporary connections for guests
- That moment when IT is out to lunch
Step-by-Step:
- On the printer’s touchscreen:
» Tap [Wi-Fi Direct] > [On] - On your device:
» Look for network names starting with “DIRECT-XX-MFC-L5850DW” - Enter the password (it’s on the back of your printer)
⚠️ Watch Out For:
- Connections time out after 60 minutes (safety feature)
- Doesn’t work with corporate/enterprise networks
Method 2: WPS Button Setup (The 30-Second Solution)
Before You Start:
- Check your router has a WPS button (usually has the symbol)
- Know that some ISPs disable this for security
The Magic Sequence:
- Press [Settings] > [Network] > [Wi-Fi] > [WPS] on your printer
- Within 2 minutes, press the WPS button on your router
- Watch the lights dance – connection happens automatically
Pro Tip: If this fails, your router might use “PIN mode” instead. Find this option in your printer’s Wi-Fi menu.
Method 3: Ethernet Setup (For Offices That Mean Business)
What You’ll Need:
- Cat5e or Cat6 cable (not included)
- A free LAN port on your switch
Office-Ready Configuration:
- Plug one end into the printer, other end into your network
- Wait for the LAN light to turn solid
- Print a Network Configuration Report (Menu > Network > Config Report) to get the IP
Network Admin Note:
- Assign a static IP if this will be a shared office printer
- Enable Bonjour/mDNS for easy Mac discovery
Troubleshooting Quick Hits:
➔ If your printer disappears from Wi-Fi after power-off: Enable “Always Online” in network settings
➔ Seeing “Not Connected” errors? Power cycle both printer and router
➔ Corporate network issues? You’ll likely need to enter proxy settings manually
