Three Steps to Clear the "No Toner" Error

Hi, everyone. 

Brother laser replacement chip in the process of installation or use may report an error "No Toner". Now let me explain why there is such an abnormal error.


It is usually caused by the following four reasons.

I. Printer structure cause. As the printer is running and printing, the toner cartridge driven by the supply roller will lead to the separation of the chip and the printer probe.

II. Installed unmatched chips.

III. Chip contacts come with stains, oxidation, gum, and other foreign objects.

IV. Deformed or damaged printer probes do not make contact with chips.


For the above abnormalities, you can carry out the following three steps and get your printer back to normal.

Step One: Operate with special movements.

Action 1: Open and close the printer cover → Wait for the printer to finish running→ Observe whether the printer returns to normal

Action 2: Open the printer cover → Remove and reinstall the toner cartridge → Close the printer cover → Observe whether the printer returns to normal

Action 3: Turn off the printer power → Wait 3 to 4 seconds before turning on the printer again → Observe whether the printer returns to normal


Step Two: Confirm whether the printer currently in use has the correct chip installed and observe whether its surface is covered with foreign objects.


1. Open the printer cover and check whether the chip coding is consistent with the printer area.

2. Remove the toner cartridge and observe whether the chip surface is covered with foreign objects.

3. If there is a foreign object, you can use industrial alcohol and non-woven fabric to erase it. If the foreign object cannot be erased, replace it with a new one.

4. Close the cover and observe whether the printer returns to normal.


Step Three: Observe whether the printer probe is deformed or damaged.


1. Remove the toner cartridge and coat the chip contacts with a water-based marker.

2. Close the cover to let the machine run for 4 to 5 seconds and observe whether the coated chip contacts show clear scratch marks.

3. No scratch marks represent a poor contact between the chip and the probe and the probe may be deformed or damaged.

4. Replace the probe (replace it yourself or contact the after-sales service for maintenance) and observe whether the printer returns to normal.
