How to Clean a Brother Printer

Keeping your printer in top shape starts with one simple habit: regular cleaning. If you own a Brother model, knowing how to clean a Brother printer properly can mean the difference between crisp, professional output and streaky, faded pages that waste paper and ink. Brother printers are workhorses — reliable, efficient, and built for the long haul — but like any precision machine, they accumulate dust, ink residue, and paper debris over time. A few minutes of maintenance every month can dramatically extend the life of your device and keep print quality sharp. Whether you have a laser, inkjet, or all-in-one model, this guide walks you through every step of the cleaning process.

If you also use your Brother device for scanning, you may want to check out our guide on how to clean printer scanner glass for clearer scans — a companion task that is just as important for scan quality. And if you are wondering how long your printer should last with proper care, our article on how long does a printer last puts it all in perspective.

Why Regular Cleaning Matters

Dust, dried ink, toner particles, and microscopic paper fibers build up inside your Brother printer every single time it runs a job. Over time this buildup causes a cascade of quality problems: horizontal lines across printed pages, smears, ghost images, paper jams, and colors that look muddy or off. In laser models, toner contamination on the drum unit is one of the most common causes of print defects — and it is entirely preventable with routine cleaning.

Beyond print quality, cleanliness directly affects hardware longevity. Rollers caked in paper dust slip and misfeed. Inkjet printheads clog when dried ink is left to harden in the nozzles. Clogged vents cause the machine to overheat. According to the U.S. Department of Energy, keeping electronics free of dust and debris also contributes to better energy efficiency, as motors and fans work less hard when airflow is unrestricted. Put simply, a clean printer is a faster, cheaper, and longer-lasting printer.

What You Need Before You Start

Tools and Supplies

You do not need an expensive kit to clean a Brother printer. Most of what you need is already in your home or office. Here is a quick reference of everything you should have on hand before you begin:

Safety Precautions

Before touching anything inside the printer, power it off completely and unplug it from the wall. Do not just put it to sleep — cut the power entirely. This protects you from electrical shock and protects the printer from accidental head movements or motor engagement. For laser printers, allow at least 10 minutes after powering off before reaching inside, as the fuser unit runs extremely hot. Never use flammable sprays near a laser printer, and never vacuum toner with a regular household vacuum — fine toner particles can pass through standard filters and become a health hazard or even ignite. Use a toner-specific vacuum or damp cloths instead.

How to Clean the Exterior and Paper Path

Cleaning the Outside Casing

Start with the outside. Dampen a lint-free microfiber cloth with a small amount of distilled water or a 50/50 water-isopropyl alcohol mix. Wring it out well — you want it barely damp, not wet. Wipe down all exterior surfaces including the top cover, front panel, buttons, display screen, and sides. Pay attention to the areas around the paper tray opening and the output tray, which collect the most hand oils and dust. For textured plastic surfaces where grime gets into grooves, a dry soft-bristle brush can dislodge debris before you wipe.

For the LCD control panel, use a dry microfiber cloth only — no liquid directly on the screen. If there is stubborn residue, dampen the cloth very slightly and wipe gently. Avoid pressing hard on the display.

Cleaning the Paper Tray and Rollers

Remove the paper tray completely and set the paper aside. Wipe the inside of the tray with a dry or lightly damp cloth, removing any paper dust or debris. Inspect the paper pickup rollers — the rubber wheels that grab each sheet from the tray. These rollers pick up a waxy coating from paper over time, which makes them slippery and causes misfeeds. Dampen a lint-free cloth with isopropyl alcohol and rotate each roller manually while pressing the cloth against it to clean the full circumference. Let the rollers dry for a few minutes before reinserting the tray.

While the tray is out, use a can of compressed air to blow out the paper feed path — the channel the paper travels through from tray to output. Short bursts work better than one long blast. This step alone can resolve many paper jam issues caused by accumulated debris.

Cleaning an Inkjet Brother Printer

Running the Built-In Printhead Cleaning Cycle

Brother inkjet printers include a built-in cleaning utility that should always be your first step when you notice print quality issues such as missing lines, faded sections, or color inconsistencies. This automated cycle forces ink through the printhead nozzles to flush out any partial clogs or dried ink deposits.

To run the cycle: on the printer's control panel, navigate to Ink (or Ink Management) → Cleaning. Select which color cartridges to clean or choose all. The printer will run for about a minute, then prompt you to print a test page. Examine the test page — if the quality has improved but is still not perfect, you can run a second cleaning cycle. Avoid running more than two or three cycles in a row without waiting, as each cycle consumes a significant amount of ink. After cleaning, print a nozzle check pattern (found in the same menu) to confirm all nozzles are firing correctly.

Manual Printhead Cleaning

If the automated cycle does not resolve the issue, a manual cleaning may be necessary. This is more involved but highly effective for stubborn clogs. First, remove the ink cartridges following Brother's standard removal procedure. The printhead assembly will be visible. Dampen a clean cotton swab or a folded lint-free cloth with isopropyl alcohol (90% or higher). Gently press it against the printhead nozzle plate — the flat metal surface with the tiny holes — and hold it there for 30 to 60 seconds. Do not scrub; let the alcohol dissolve the dried ink. Repeat with fresh swabs until no more ink transfers onto the cloth.

For severe clogs, some users place a few drops of distilled water or isopropyl alcohol directly onto a paper towel, lay the printhead face-down on it, and let it sit for 10 to 15 minutes to soak. This can dissolve hardened deposits that a swab alone cannot remove. Reinstall the cartridges, run one automated cleaning cycle, and print a test page. The improvement is usually dramatic.

If you frequently use your Brother device for specialty media, be aware that different paper types interact with ink differently. For example, our guide on how to print on transparency sheets with an inkjet printer covers media settings that can affect how much ink is deposited — and therefore how quickly heads can clog with heavy use.

Cleaning a Laser Brother Printer

Laser printers work on completely different principles than inkjet models — they use a static electric charge to attract fine toner powder to a drum, which is then fused onto paper with heat. Cleaning a laser Brother printer focuses on three main areas: the drum unit, the corona wire, and the interior cavity.

Cleaning the Drum Unit

Open the front cover of your Brother laser printer and carefully slide out the toner cartridge and drum unit assembly. If your model separates these two components, set the toner cartridge aside on a flat surface away from direct light (light can damage the toner). Examine the green or blue drum surface. If you see a mark, spot, or scratch that corresponds to a repeating defect on your printed pages, the drum may need cleaning — or replacement. For surface contamination like toner dust or paper residue, use a dry lint-free cloth and wipe very gently. Never use alcohol, water, or any liquid directly on the drum surface, as this will permanently damage it.

If you need to replace the drum entirely, our guide on how to replace a printer drum unit walks through the full process step by step — it is simpler than most people expect.

Cleaning the Corona Wire

The corona wire is a thin wire inside the drum unit that charges the drum surface. When it gets coated with toner dust, it cannot charge evenly, resulting in dark vertical streaks or shading on prints. Many Brother drum units include a small plastic tab or slider specifically for cleaning the corona wire. Simply slide it back and forth gently several times from one end to the other to dislodge debris — Brother typically includes instructions on the drum unit itself (look for a printed arrow or label).

If your drum unit does not have a built-in slider, use a dry cotton swab and very gently stroke it along the length of the wire. Work slowly and carefully — the wire is extremely delicate and will break if pulled or pressed too hard. A broken corona wire means replacing the entire drum unit.

Cleaning the Interior

With the drum unit removed, you have clear access to the interior cavity of the printer. Use a can of compressed air (held upright, in short bursts) to blow loose toner dust and paper debris out of the cavity. Have paper towels or a cloth ready to catch debris that falls out the front. You can also use a dry lint-free cloth to wipe down interior plastic panels and the paper path guides. Pay attention to the fuser unit area at the back of the paper path — paper dust accumulates heavily here. Do not touch the fuser rollers themselves, as finger oils will degrade them.

Once the interior is clean, slide the drum unit back in, close the cover, and run a test print. If streaking was caused by a dirty corona wire, the improvement will be immediate and obvious.

Recommended Cleaning Schedule and Frequency

How often you need to clean your Brother printer depends on how heavily it is used and the environment it operates in. Dusty offices, high-volume workgroups, and printers near vents or windows need more frequent attention than a light-use home printer in a clean room. As a general framework, follow this schedule:

Monthly (light use) or weekly (heavy use): Wipe down exterior surfaces, clean paper tray, run a nozzle check (inkjet) or print a test page (laser) to catch emerging issues early.

Every 3 months or every 1,000–2,000 pages: Clean the pickup rollers, run the built-in printhead cleaning cycle (inkjet), clean the corona wire and interior cavity (laser).

Every 6–12 months or when print quality declines: Perform a full deep clean including manual printhead cleaning (inkjet) or drum inspection and possible replacement (laser). For all-in-one models, also clean the scanner glass and ADF roller — see our dedicated guide on how to clean printer scanner glass for the full procedure.

If you use your Brother MFC model frequently for envelope or specialty media printing, be aware that these jobs can stress rollers and heads more than standard letter-size paper. Our guide on how to print envelopes on Brother MFC printer covers the media and settings adjustments that help reduce wear and the need for extra cleaning.

Consistent cleaning is one of the most cost-effective investments you can make in your printer. Replacement drum units, printheads, and even full printers cost significantly more than the few minutes of effort a cleaning routine requires.
