Brother MFC-L2710DW Toner Replacement, No-Print Fixes, and Electrician Label Printer FAQ

In my role coordinating equipment repairs for small offices, I am the person who gets called when a printer stops working next to a deadline. Last quarter alone I logged 47 no-print calls. Most did not need a new printer. More than a few did not even need a service visit.

The questions below are the questions I keep answering on the phone. If you search for Brother toner replacement, Brother MFC-L2710DW help, HP Photosmart printer replacement advice, or you are an electrician trying to decide whether to buy a dedicated label printer, this should save you some time.

Why is my printer not printing even though it looks ready?

Start with the print queue, not the hardware. On a Brother MFC-L2710DW, a stuck job on a PC will make every later job wait. Open Devices and Printers, right-click the Brother, and take a look at the queue. Cancel anything that is paused or stuck.

Then check the default printer. I know it sounds basic, but I have spent 30 minutes replacing toner only to discover that a Windows update had switched the default back to an old HP Photosmart printer. That printer was in another room and did not even have ink. Every job was flying there. The Brother was not the problem.

If the queue is empty and the default is correct, restart the print spooler. Press Windows+R, type services.msc, find Print Spooler, right-click it and restart. Then try a test page from the printer's own menu. If the test page prints, the printer is fine and the problem is on the computer. That one sentence has saved more unnecessary toner orders than any other advice I give.

How to replace toner in a Brother printer: MFC-L2710DW steps

First know which part is which. The MFC-L2710DW uses a TN-730 or TN-730XL toner cartridge and a separate DR-730 drum unit. You normally replace the toner cartridge and keep the drum unit. The drum unit can last several toner changes.

1. Turn the printer off and open the front cover.
2. Pull out the toner and drum assembly using the green handle. Set it flat on a clean sheet of paper, with the drum surface out of direct light.
3. Press the green lock levers and pull the old toner cartridge out of the drum unit.
4. Unpack the new TN-730 series cartridge. Follow the arrows on the packaging and remove any protective strip or cap if one is present. Brother's instructions, which are on support.brother.com, are model-specific, so check their drawings if anything looks unusual.
5. Slide the new cartridge straight into the drum unit until the lock levers click.
6. Reinsert the whole drum and toner assembly into the printer. Close the front cover and let the printer initialize.

Do not touch the green surface on the drum unit when you install the cartridge. Fingerprints can leave print defects.

Does the Brother MFC-L2710DW need a new drum every time I replace toner?

No. Brother separates these for a reason. The toner cartridge holds the powder. The drum unit is the photoreceptor that transfers the powder to paper. They wear out at different rates.

According to Brother's consumable specs at support.brother.com as of April 2025, the TN-730 is rated for about 1,200 pages, the TN-730XL for about 3,000 pages, and the DR-730 drum for about 12,000 pages. Those numbers assume roughly 5 percent page coverage, which is typical for a plain text page. Heavy graphics will shorten toner life, and a dusty office can affect drum life.

How do you know which one to replace? If the page looks faded and there is no repeating mark, try toner first. If a black line or mark repeats at the same interval down the page, that is usually drum wear. People think a new toner cartridge fixes every light print. Not when the drum is worn.

Can the Brother MFC-L2710DW replace an old HP Photosmart printer?

If your HP Photosmart printer is still doing what you need, keep it. No need to create a technology problem. If you are replacing it because it no longer prints reliably, or because the ink situation is driving you crazy, the answer depends on what you print.

The MFC-L2710DW is a monochrome laser. For contracts, invoices, letters, and black-and-white documents, it is a solid choice. It produces sharp text, feeds paper well, and the separate toner and drum help keep page costs reasonable once you are past the initial purchase.

It is not a photo printer. If you scan family pictures or print glossy color photos, keep a color inkjet device around. An HP Photosmart can be that device. I tell clients to think about the last two months of printing. If five percent or less of it was color photos, a monochrome Brother is probably enough. If you are color-heavy, buy a color inkjet, not a mono laser. That recommendation is boring, but it saves money and desk space.

What is an electrician label printer and do I need one?

An electrician label printer is a portable thermal label printer that makes labels for wires, breakers, and panels. The category exists because paper office labels do not survive where electricians work. Oil, heat, friction, and time all make a paper label unreadable.

What should you look for? The tape system matters more than the printer brand. A Brother P-touch machine with laminated tape choices gets used more because it can handle different jobs. A 12 mm tape can label individual wires, while a wider tape is better for panel schedules or warning signs.

If the labels need to pass an inspection, verify the exact code requirement before buying anything. The local authority having jurisdiction has the final word, and labeling standards change. Whatever the box says, do not assume an office label maker is automatically code-compliant for electrical work.

Brother MFC-L2710DW not printing after a toner replacement. Now what?

More often than not, the toner cartridge is seated incorrectly or the front cover is not completely closed. Both are normal mistakes, especially when you are in a hurry. Open the printer, pull out the drum and toner assembly, and push the cartridge back in until the green lock levers click. Reinsert the assembly as one piece, close the front cover, and wait for the machine to initialize.

Then print a test page from the printer menu, not from the computer. If the test page prints, the printer itself is ready. If a network job still will not print, go back to the queue and clear the old job. Sending the same file again is often where people get stuck: they click print, nothing happens, and they assume the toner replacement caused the problem. Usually it did not. The old job was frozen.

If the test page is blank, do not install another toner cartridge yet. Remove the drum and toner assembly and confirm that the new cartridge is fully snapped in and that no protective strip is blocking the opening.
