2. Installation

  1. Take out the drum and toner assembly, remove the orange protective part, then push the toner into the drum until the lever clicks.
  2. Load paper, then connect power. Do not connect USB until the driver asks for it.
  3. Set up wireless from the control panel: Menu, Network, WLAN, Setup Wizard, then choose the network and enter the key. WPS also works if your access point has the button.
  4. Print the Network Configuration Report from Menu, Print Reports to confirm the address.
Keep the packaging until the machine has printed a few hundred pages without fault. Transport damage often shows up in the first week, and returns are simpler in the original box.

4. Maintenance schedule

Intervals below are for typical office use. Machines in dusty rooms or running heavy graphics need the shorter end of each range.

Every toner changeSlide the green tab on the drum from side to side three times to clean the corona wire, then return it to the home position. Marks in a vertical line usually come from skipping this.
Every 12,000 pagesDrum unit reaches its rated life. The panel warns well before print quality drops.
Every 6 monthsRemove the tray and wipe the pickup roller and the tray dust with a dry cloth.
As neededRun the drum cleaning routine from the Print Reports menu to identify which part causes a mark.

5. Common faults

Drum End Soon warning but prints are fine

The drum counter is time-and-page based. You can keep printing, but order a replacement; quality falls off quickly once it starts.

Vertical white line down the page

Corona wire needs cleaning, or toner is low on one side. Slide the green tab first, before anything else.

Printer goes offline on Wi-Fi every night

Router power saving or band steering. Fix the printer to the 2.4 GHz band and give it a DHCP reservation.

Manual feed pulls the sheet crooked

The single-sheet slot needs the sheet pushed in until the printer grips it. Release it as soon as the feed starts, do not hold it.

Toner Ended and printing stops

Brother stops rather than fades. If you must finish a job, Continue mode is in the General Setup menu, but print quality is no longer guaranteed.

Switch the machine off at the mains and let the fuser cool for at least thirty minutes before reaching into the paper path. Fuser assemblies run above 180 °C in normal operation.
