Key takeaway
On the printer ink vs toner question: inkjet printers use liquid ink, and laser printers use toner, a fine dry powder fused to the paper with heat. Around those two, printers have other consumables: printheads on inkjets, drum units and sometimes waste toner containers on lasers, and maintenance boxes on some inkjets. Knowing which ones your printer uses helps you budget, buy the right parts and understand its warnings.
Terms used in this guide
- Consumable: any part designed to run out or wear out and be replaced by the owner.
- Ink cartridge: a sealed container of liquid ink. Some include the printhead; others hold ink only.
- Toner cartridge: a container of dry toner powder for a laser printer. Some include the drum.
- Drum unit: the light-sensitive cylinder in a laser printer that carries the toner image before it transfers to paper.
- Maintenance box (waste ink box): a part in some inkjets that absorbs ink used during cleaning.
The consumables, one by one
Ink
Liquid ink sits in cartridges or, on ink tank printers, in refillable reservoirs. Inkjets usually use dye-based inks, pigment-based inks, or a mix. Pigment black is common for crisp text; dye colors are common for vivid photos. Ink can dry in the printhead if a printer sits unused, which is why inkjets run cleaning cycles.
Printhead
The printhead is the part with tiny nozzles that fire ink onto the page. On some printers it is built into every cartridge, so you get a new one each time you replace ink. On others, especially ink tank models, it is a permanent part of the printer designed to last a long time. A few printers have a printhead that the owner can replace as a separate part; the manual will say so.
Toner
Toner is a very fine powder of plastic and pigment. A laser printer attracts it to an electrostatic image on the drum, transfers it to paper, and the fuser melts it in place. Toner doesn’t dry out, so laser printers handle long idle periods well. Because the powder is so fine, handle cartridges gently and avoid breathing any spilled toner.
Drum unit
The drum receives the image from the laser and picks up toner. It gradually wears with use. Many home lasers combine the drum and toner in one cartridge; others use a separate drum that lasts through several toner cartridges. Printers usually show a message when the drum is near the end of its life.
Waste toner container and maintenance box
Some color lasers collect leftover toner in a waste toner container, and some inkjets collect ink from cleaning cycles in a maintenance box. When either is full, the printer asks for a replacement. On printers without a user-replaceable box, the manufacturer may need to service the part when it is full.
Fuser
The fuser uses heat and pressure to bond toner to paper. On most home printers it is designed to last the printer’s life, but some business lasers treat it as a replaceable maintenance part. It gets very hot, so never reach toward it while the printer is on or warm.
Ink and toner compared
| Factor | Ink (inkjet) | Toner (laser) |
|---|---|---|
| Form | Liquid | Dry powder |
| How it reaches paper | Sprayed through nozzles | Transferred from a drum, then fused by heat |
| Drying out | Can dry in nozzles if unused | Does not dry out |
| Smudging | Can smear if wet or highlighted | Dry and fixed as it leaves the printer |
| Other parts it relies on | Printhead, sometimes a maintenance box | Drum, fuser, sometimes a waste container |
| Typical strengths | Photos and color graphics | Sharp text, steady volumes |
How to find out what your printer uses
- Find the model number. It is on the front, top or a label on the back or underneath.
- Look up the supplies list. The manual or the manufacturer’s support site lists every consumable with its code: ink or toner, drum, maintenance box and any others.
- Check what is installed now. Open the covers the manual shows and read the labels on the installed supplies.
- Check status in software. Many printers show supply levels on their screen, in their app or on their web page.
You should now have: a list of your printer’s consumables and their part codes, which you can use when shopping. Our guide to cost per page shows how to turn those codes into running-cost estimates.
Disposal and recycling
Many manufacturers run take-back programs for used cartridges, and some retailers accept them. Local electronics recycling programs may also help; the US EPA lists options for electronics donation and recycling. Put used toner cartridges in the bag from the new one to avoid spills, and keep used ink cartridges upright so they don’t leak.
When to get more help
If the printer reports a problem with a part you can’t find in the manual’s list of user-replaceable items, such as an ink pad or fuser error on a home printer, contact the manufacturer’s support rather than opening the printer. The same goes for leaks inside the printer or a strong burning smell. Our guide to replacing and storing ink and toner covers safe handling of the parts you are meant to change.
Common questions
Can I use ink in a laser printer or toner in an inkjet?
No. They work in completely different ways. Use only the supplies listed for your exact model.
Why does my printer say the drum needs replacing when I just changed the toner?
On printers with a separate drum, the drum and toner wear out at different times. Replacing the toner doesn’t reset the drum. Check the manual for your model’s drum replacement steps.
Is toner dangerous?
Used as intended, toner stays inside the cartridge. Avoid breathing spilled toner, keep it away from children and pets, and follow the safety information on the packaging or the manufacturer’s safety data.
What is a maintenance box, and do all printers have one?
It collects ink used during cleaning on some inkjets. Not all printers have a replaceable one. The manual tells you whether yours does.
