Still says toner low after replacing the cartridge
New toner in, but the printer still says low, empty or replace? Check whether it means the drum, remove the packaging, reseat it and read a supplies page.
You’ll need: A sheet of paper to rest the cartridge on · A dry lint-free cloth

Read the message word for word. Many laser printers have a separate drum unit, and messages that mention the drum are easily mistaken for toner warnings; a new toner cartridge won’t clear them. If it really says toner, take the cartridge out, make sure every seal and spacer is gone, rock it gently side to side, and push it back in until it locks.

Check whether it means toner or drum
Write down the exact message. On printers with a separate drum unit, a drum warning means the drum is near the end of its rated life, and replacing the toner won’t clear it. If it is a drum message, plan to replace the drum when print quality drops, then follow the drum reset steps in your manual; reset it only after fitting a new drum.
You should see: You know whether you are dealing with toner or the drum.
-
Remove all packaging from the cartridge
Take the new cartridge out and compare it with the instruction sheet from its box. Pull out any sealing strip or tape, and remove colored plastic spacers, clips or guards. A cartridge with its seal still in place can fit and lock but deliver no toner, and some printers then report it as empty.
You should see: No tape, tabs or plastic guards remain on the cartridge.
-
Rock the cartridge to spread the toner
Hold the cartridge level with both hands and rock it gently side to side five or six times. Toner settles during shipping and storage, and spreading it evenly helps the first pages print with full density.
-
Seat the cartridge and lock it
If your printer combines a drum unit and a toner cartridge, push the toner into the drum unit until it clicks and any lock lever lifts, then slide the assembly in until it stops. With a single-piece cartridge, push until it locks. Close the front cover firmly.
You should see: The cover closes flush and the printer begins its start-up routine.
-
Wipe the cartridge contacts
If the cartridge has a chip or metal contacts, wipe them and the matching contacts in the printer with a dry lint-free cloth. Toner dust on the contacts can stop the printer reading a new cartridge correctly.
-
Restart the printer
Switch the printer off with its button, unplug it for 60 seconds, then plug it back in and switch it on. Let it finish warming up, which can take a minute or two after a cartridge change.
You should see: The toner gauge shows full or close to it.
-
Print a supplies status page
From the printer’s menu, print the supplies status, configuration or printer settings report. It shows the toner level in detail, and often whether the cartridge is seen as genuine, used or unrecognized, which tells you whether the printer is reading the new cartridge at all.
You should see: The report lists the new cartridge with a high remaining level.
-
Check how the printer handles empty toner
Some laser printers have a setting that decides whether they stop or carry on when toner reaches its end, sometimes called continue mode. If a remanufactured cartridge is full but the printer stops, check your manual for this option and ask the seller for a replacement with a properly reset chip or counter.
Did this fix it?
Good to hear. If the problem comes back, the steps will still be here, and your ticked steps are saved on this device.
Try these next:
- Check for a firmware update for your model on the manufacturer’s official support site. Updates sometimes change how cartridges are recognized, so read the notes first if you use non-original toner.
- If you moved a cartridge from another printer, check both printers for a cartridge protection or supply policy setting. Some office lasers lock a cartridge to the first printer it was used in, or accept only genuine supplies when set to.
- If pages are faint as well as the message being stuck, try the old drum or a different toner cartridge, if you have one, to see which part is causing it.
Still stuck? Run the diagnose questions, or check your printer’s manual and the manufacturer’s official support site.
Common questions
Do I need to reset anything after changing toner?
Usually not; most laser printers detect a new toner cartridge on their own. The drum is different: on many printers with a separate drum unit, you reset its counter after installing a new drum, following the steps in the manual.
Why does a remanufactured toner cartridge show low straight away?
The printer reads the level from the cartridge’s chip or a counting mechanism. If the remanufacturer didn’t reset it, the printer still sees the old, empty cartridge. Contact the seller; reputable ones replace faulty units.
Can I ignore the toner low message?
Yes, as long as prints still look good. Low warnings come early, and many printers keep printing well after them. Keep a spare ready for when pages start to fade.
