Low
Usually safe to check without specialist tools.
Urgency
Medium
Quick answer
The printer is telling you the toner has run out and the toner container must be replaced. Toner is running out usually appears first so you can have one ready. Replace the container, shake the new one before fitting it and close the front cover.
Safety first
Stop and check this first
- Do not incinerate the toner container: Kyocera warns that dangerous sparks may cause burns.
- Keep toner out of the reach of children; if it spills, avoid inhaling or swallowing it and contact with eyes and skin, and do not force the container open.
Safe checks you can perform
- Read the exact message on the display
- Replace the toner container
- Check the container and cover are seated
- Clean the inside after replacing it
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check by Kyocera authorised service
- Do not attempt this professional task: Return the empty container

Clean the inside after replacing it
- Who:
- you, following the guide for your model.
- How:
- with the front cover open, lift out the developer unit with the toner container and then the drum unit, lay them flat on a clean surface, wipe the metal registration roller with a lint free cloth, slide the main charger cleaner back and forth 2 or 3 times and return it to its home position.
- Result that matters:
- keeping print quality; Kyocera asks you to clean these parts every time you replace the container.
- If prints come out clean:
- nothing more to do.
- If vertical lines still appear:
- ask Kyocera authorised service.
- Evidence to keep:
- a test page before and after cleaning.
Do not touch the drum or expose it to direct sunlight or strong light.

What it means
On the ECOSYS M2030dn, M2035dn, M2530dn and M2535dn, Kyocera's guide shows Add toner, with the attention LED lit, when the toner container must be replaced, and Toner is running out when you should prepare a new one. On the M2135dn, M2040dn and M2540dn the Spanish guide uses Sustituir tóner. Life depends on how much toner your jobs use: Kyocera gives 3,000 images for the M2135dn and 7,200 for the M2040dn and M2540dn. The message alone never proves that any part is faulty.
