Do Laser Printers Use Ink or Toner?

A laser printer uses toner powder instead of liquid ink. The powder forms text and images on the page, then heat helps fuse it to the paper.

The wording on some supply pages can be confusing. A product specification may call its output color “ink color,” even when the printer is a laser model.

For a laser printer, check the compatible cartridge or supply guide for the word toner and a cartridge code. For help identifying supplies, read what ink your printer needs.

Most home and office laser models print black text with black toner. Color laser printers use separate toner cartridges for multiple colors, but don't assume a model supports color just because it has a scanner or copier.

If you're choosing a printer as well as its supplies, start with the home printer buying guide. For a model that focuses on black-and-white printing, compare the best laser printer for home use.

How does laser printer toner work?

Toner is a dry powder that gets transferred and fused onto paper. The printer forms the image, places toner where it belongs, and uses a heated fuser to bond it to the page.

That process is why laser supplies differ from inkjet cartridges. Toner isn't a liquid, and a laser printer can't use an ink cartridge in its place.

Toner can spill if a cartridge is handled roughly or damaged. Keep it sealed until installation, follow the printer's replacement steps, and avoid touching any parts the manual identifies as sensitive.

What supplies does a laser printer need?

At minimum, a laser printer needs the toner cartridge specified for its model. Some printers also have a separate drum unit, while other designs combine the drum and toner into one replaceable cartridge.

The toner cartridge holds the powder used to print. The drum unit transfers the image as part of the printing process; on models with a separate drum, it may have a different replacement schedule from the toner.

Don't buy a drum just because you're replacing toner. Check the printer manual or its manufacturer supply guide to see whether the drum is separate, which part needs replacing, and the compatible part number.

Paper is another supply to match to the job. Check the printer's supported paper sizes and types before using labels or envelopes, and follow its instructions for loading them.

How can you find compatible laser printer toner?

Match the full printer model and toner code before you buy. The words “laser toner” alone aren't enough because cartridge shape and compatibility vary by model.

Use this quick check:

Find the printer's full model number on its front, back, or settings menu.
Check the manual or manufacturer's supply guide for the toner code.
Match the code exactly, including a standard or high-yield version if offered.
Check separately whether the printer needs a drum unit.
Confirm that the cartridge is intended for your region and printer model.

A higher-yield cartridge may be an option for people who print more often, if the manufacturer identifies it as compatible. It doesn't mean every cartridge with a similar name will fit.

Is third-party toner compatible?

Third-party toner may be made for certain printer models, but compatibility and print results can vary. Check the cartridge code and the printer maker's guidance before choosing one.

Use a cartridge designed for your exact model. A toner that fits physically may still fail to work as expected if its chip, shape, or cartridge code doesn't match.

Which laser printer supplies does a Brother printer use?

Brother laser printers use the toner and drum parts specified for each model. Check the model number and its supply codes before ordering, even when two printers look similar.

The Brother DCP-L2640DW, MFC-L2820DW, and HL-L2405W use TN830 or TN830XL toner. The HL-L2405W also lists a TN830XL two-pack option, and its drum unit is DR830.

The DCP-L2640DW and MFC-L2820DW are multifunction printers with printing, scanning, and copying; the MFC-L2820DW also includes fax. For more models, see our Brother laser all-in-one printer guide.

The HL-L2405W is a print-only model, so it's a simpler fit if you only need printing.

Choose this model if you want one device for printing, scanning, and copying. It has built-in dual-band wireless, Ethernet, and USB connections.

This model suits a small office that needs faxing along with printing, scanning, and copying. It offers dual-band wireless, Ethernet, and USB connections.

Consider this model if you need a printer without scanning or copying functions. It connects over dual-band wireless or USB.

Why does a laser printer have a drum unit?

A drum unit is a separate part in some laser printers, and it isn't the same thing as toner. Toner supplies the powder; the drum helps transfer the printed image.

On printers with separate units, the toner cartridge and drum may need replacement at different times. Follow the printer's alerts and manual rather than replacing both parts automatically.

A cartridge may include toner even if the printer also uses a separate drum. Check the package contents and compatible part codes so you know which supply you're replacing.

Can a laser printer print photos or color pages?

A monochrome laser printer prints in black and white, while color output requires a color laser printer. Check the printer's supported output before buying toner or paper for a photo or color job.

Laser printers can print images, but the result depends on the model, paper, and kind of image. They aren't all designed for the same color or photo work.

An ink-tank printer is a different option if you want an ink-based system. For example, our Epson EcoTank ET-4800 printer reviews cover a printer in that category.

What should you check before replacing toner?

Confirm the printer model, toner code, and any separate drum requirement. Those checks help prevent ordering a cartridge that looks similar but isn't made for your printer.

Before you install a replacement, read the printer's instructions. Keep toner away from children and pets, avoid inhaling dust if a cartridge spills, and use the cleanup method recommended by its manufacturer.

If the printer reports low toner, check whether print quality has changed and follow the manual's guidance. Some printers allow a brief continuation, while others stop or require a replacement.

Do laser printers use ink? The buying rule

For a laser printer, buy the compatible toner code, not an ink cartridge. Check whether your model uses a separate drum, then choose the supply type and yield that fit your printing needs.

Choose a multifunction model if you also need scanning or copying, and a print-only model if you don't. For a different way to handle documents and photos, compare an ink-tank printer or a flatbed scanner for negatives and slides.

Frequently asked questions

Do laser printers use ink or toner?

Laser printers use toner, a fine powder, rather than liquid ink. The printer transfers toner to the page and uses heat to bond it to the paper.

Check your model number before buying supplies, because toner cartridges are not universal.

Do laser printers need both toner and a drum?

Some laser printers use a separate drum unit as well as a toner cartridge, while others combine those parts. Check the manual or supply guide for your exact model to see which parts need replacement and whether the drum is sold separately.

Can you use ink in a laser printer?

No. Ink cartridges are made for inkjet printers, while laser printers use toner powder and a different printing process.

Use the toner cartridge specified for your printer model; an ink cartridge won't work as a substitute.

How do I find the right toner for my printer?

Find the printer's full model number and check its manual or manufacturer supply guide for compatible toner codes. Match the cartridge code exactly, including any standard or high-yield version, and check separately whether your model uses a replaceable drum unit.
