Compatible Kyocera TK-1120 toner: installation, chip reset and savings guide
Actualizado 18 julio 2026Share
The compatible Kyocera TK-1120 toner is a 3,000-page black cartridge manufactured to the ISO 9001 standard, designed as a direct replacement for the original in ECOSYS-series monochrome laser printers. Here we explain which models it fits, how to install it, what to do if your machine says it "does not recognise the cartridge" and why its yield stays in line with the branded consumable.
What it is and which printers it fits
It is a black toner cartridge with a declared yield of 3,000 pages at 5% coverage, the ISO/IEC 19752 measurement standard. It is compatible exactly with these machines:
- Kyocera ECOSYS FS-1025MFP
- Kyocera ECOSYS FS-1060DN
- Kyocera ECOSYS FS-1125MFP
If you have one of these models, this is the consumable you need. If your machine is from the higher range and uses more, take a look at the higher-yield toners such as the compatible TK-1160 with a 7,200-page yield or the compatible TK-1170, and if you are looking for the same-yield alternative for another series, the compatible TK-1150 with a 3,000-page yield.
How to install it and what to do if it "does not recognise the cartridge"
Installation is the same as for an original cartridge:
- Open the front cover and remove the empty cartridge by pulling the lever.
- Gently shake the new cartridge horizontally several times to distribute the toner.
- Insert it until you hear the locking click and close the cover.
ECOSYS printers usually accept the compatible cartridge without any issues. If a non-genuine toner or low-level warning appears when you install it, bear in mind that on this series the message is informational: by pressing OK or Continue the machine carries on printing normally. If the warning persists, switch the printer off, wait a few seconds, remove and refit the cartridge making sure it clicks into place properly, and switch it back on so the reading resets. As it is a consumable with a new chip, you do not need any manual counter resets.
Yield and savings compared with the original
The yield is equivalent to that of the branded cartridge: 3,000 pages under ISO conditions, with a stable print density from start to finish thanks to ISO 9001 quality control. Where everything changes is the cost per page, which is reduced considerably compared with the original without sacrificing text sharpness or reliability. If you want to work out what that means in your case, we break it down in our article on the real cost of printing, and if you have doubts about the difference in results, take a look at our original vs compatible printed side by side comparison.
