If you typed “how to clean brother printer” because your Brother DCP-T310 ink tank printer is streaking, do not buy another cleaning sheet yet. In most cases, the problem is not a dirty machine. Run the built-in nozzle check first, then the cleaning cycle, and then change the paper if needed. As a quality compliance manager, I review more than 200 Brother printer units a year, and about 60% of “dirty printhead” complaints trace back to paper, humidity, or supply issues—not the printer itself.

Bottom line: use the printer’s own maintenance tools before you touch anything. If the nozzle pattern has gaps, run the cleaning utility once. Wait 15 minutes. Print another pattern. If that still shows missing lines, run a power cleaning. Only after those steps should you clean the paper path or exterior manually. Repeating the normal cleaning cycle five times is not a fix—it’s a $20 ink drain.

If you’ve ever watched a printer smudge every page ten minutes before a deadline, you know that sinking feeling. That pressure makes people do dumb things, like wiping the printhead with a coffee filter. I’ve seen the results.

Why I’m picky about this

I’m a quality/brand compliance manager for an office equipment distributor. Every Brother printer that goes through our warehouse is checked before it reaches the customer. That’s roughly 220 unique units a year. In 2024, I rejected about 3% of first deliveries. The reasons ranged from cosmetic scratches to a printhead whose nozzle pattern showed three missing lines. Rejected units went back to the manufacturer or were serviced on-site before we sent them out.

What surprised me, though, wasn’t the rejection rate. It was how many “defective” units cleared up after one routine cleaning cycle. I’ve seen a $350 printer labeled as broken when the actual fix was a 10-minute maintenance step the previous user had never run. Okay, maybe I’m overstating it. It’s not that every issue can be fixed with a cleaning cycle. But enough can.

Here’s something vendors won’t tell you: “cleaning” in a Brother printer menu does not mean wiping the outside. On an ink tank model, it pulls ink through the nozzles to dislodge dried ink. That is the equivalent of unclogging a tiny pipe. Skipping that step and wiping the printhead with a random cloth is how people make a serviceable printer worse.

The Brother DCP-T310 ink tank printer: how to clean it without breaking it

If you own the Brother DCP-T310 ink tank printer, the routine is a little different from a standard inkjet. Because the ink tanks are refillable and the printhead is designed to last, the most important job is keeping the ink system free of dried ink. So here’s the order I recommend:

  1. Print a nozzle check pattern. Use the status monitor or Brother software. If the pattern has thin lines or missing colors, proceed to the next step.
  2. Run the cleaning cycle once. On the DCP-T310, this is under the maintenance or utilities menu. Let the printer finish, then wait 15–20 minutes so the ink has time to dissolve.
  3. Print another nozzle check. If the pattern is now clean, stop. You are done.
  4. If normal cleaning doesn’t work, try power cleaning. It uses more ink. I treat this as the next step, not the first step.
  5. Clean the exterior and paper path only after the ink system is clear. Unplug the printer, remove paper, and wipe accessible rollers with a lint-free cloth dampened with water.

One caveat: I’m not telling you to disassemble the printhead. If the printer is under warranty, that can void it. I can only speak to the steps Brother support actually documents. If you hear a grinding noise when the carriage moves, or if the printer still says paper jam after you remove every sheet, stop and call Brother support. No change after two cleaning cycles is also a red flag.

If the nozzle pattern is clean but the page still smudges, suspect paper before you suspect hardware. Standard copy paper is 20 lb bond (roughly 75 gsm). Damp, recycled, or bent paper can cause smearing that looks exactly like a dirty printhead.

The measurement I keep coming back to

When I check a printed page, I’m looking at more than whether the text is dark enough. For office documents, 300 DPI at final size is the standard minimum; for text-heavy print, 600 DPI is better. If a logo needs a precise brand color, the tolerance is usually Delta E < 2, according to Pantone color matching guidelines. You do not need an eigenvector calculator to measure any of this—the printer’s nozzle check and alignment page will tell you more than a matrix ever will.

Office math: what a TI 84 calculator online can and can’t do

I get why people look for a TI 84 calculator online when they’re trying to figure out if a printer is worth repairing. Long division is easier on a screen than in your head. But the math that matters in printer maintenance isn’t hard. Track the page count, divide the cost of ink by the number of pages you got, and compare that with a new machine. A calculator will not tell you whether the printhead is clogged or whether the ink tube has an air bubble. That requires a visual check.

Who invented the 3D printer? (You’ll see why this matters)

Since this guide gets grouped with other printer questions, let’s answer one I didn’t expect: who invented the 3D printer? Chuck Hull invented stereolithography in 1983 and patented it in 1986. He co-founded 3D Systems, which commercialized it. It matters to me as a quality inspector because 3D printing and inkjet printing share a core principle—small, precise deposits of material with a calibration that has to be right from the first layer. The Brother DCP-T310 ink tank printer is not a 3D printer, but it follows the same logic in reverse: if the first nozzle pattern is wrong, every page afterward is wrong too.

When cleaning won’t fix it, and why certainty is worth paying for

Cleaning doesn’t fix a logic board, a broken pickup roller, or a printhead that has been dried out for six months. If the nozzle pattern still has gaps after one power cleaning, that’s a signal to call for service. I’ve been in that spot. In March 2024, we paid an extra $300 for an express service visit. The alternative was missing a $15,000 print run for a client. I’d make the same call again. The premium wasn’t for speed, exactly. It was for certainty.

That logic also applies to supplies. Genuine Brother ink and approved paper are more expensive than bargain alternatives, but they remove one variable from the troubleshooting process. In a deadline situation, a “probably compatible” cartridge is not a plan. It’s a gamble. I have mixed feelings about cleaning kits too—some are useful, but many contain harsh solvents that leave residue on rollers. In our warehouse, a residue issue once made 200 sheets stick together. That was not the printer’s fault. Once you’ve seen what a residue-loaded roller does to a print run, paying for the official service route becomes a no-brainer.

Boundary conditions (what this guide is not)

This guide is for the common situation: a Brother printer that has smudged, streaked, or gone light. It is not for a printer that was soaked, dropped, or exposed to a power surge. If the printer is physically damaged, cleaning will not help.

This worked for us in a controlled office environment with reasonable humidity and standard paper. If you run a print shop in a humid basement or you use heavy coated paper, your mileage may vary. I can only speak to the maintenance patterns I’ve seen across hundreds of Brother units. For anything else, Brother’s official support documentation is the source that matters.
