Keep the upper right front cover closed except when replacing the toner bottle.
If the message appears even when there is a lot of toner, pull out the toner bottle following the instruction displayed on the screen, and then reinstall it.
When a toner bottle with toner remaining is removed, the amount of remaining toner, the date the bottle was replaced, and other information about the toner are stored in the machine.

Precautions When Storing Toner
- Do not store toner (new or used) or toner containers while toner is inside in a place with an open flame. The toner can ignite and result in burns or fire.
- Do not leave the following items in a place where children can reach them:
Toner (new or used)
Toner containers while toner is inside
Toner-attached parts
Precautions When Replacing the Toner
- Do not dispose of the following items into a fire. Toner will ignite on contact with naked flame and burns can result.
Toner (new or used)
Toner containers while toner is inside
Toner-attached parts
- Do not absorb spilled toner (including used toner) using a vacuum cleaner. Absorbed toner may cause ignition or explosion due to electric contact sparks inside the vacuum cleaner. However, you can use a toner-compatible industrial vacuum cleaner. When toner is spilled, remove the spilled toner using a wet cloth so that the toner is not scattered.
- The following explains the warning messages on the plastic bag used in this product's packaging:
Do not leave the polythene materials (bags, etc.) supplied with this machine close to babies and small children. Suffocation can result if polythene materials are brought into contact with the mouth or nose.
- When the following occurs while toner is handled, receive emergency measures first, and then consult a doctor if necessary.
When inhaling toner, gargle with a large amount of water and move into a fresh air environment.
When swallowing toner, dilute gastric contents with a large amount of water.
When getting toner into your eyes, flush them with a large amount of water.
- When removing jammed paper, replenishing or replacing toner (new or used), make sure not to inhale toner.
- When removing jammed paper, replenishing or replacing toner (new or used), be careful not to have toner dirt your skin or clothes.
- If toner (new or used) comes into contact with your skin or clothes and smears them, take the following actions:
If toner comes into contact with your skin, wash the affected area thoroughly with soap and water.
If toner comes into contact with your clothes, wash the stained area with cold water. Heating the stained area by applying hot water will set the toner into the fabric and removing the stain may become impossible.
- When replacing a container with toner (including used toner) or consumables with toner, be careful that the toner does not splatter. After removing used consumables and shutting the lid of the container if the lid is available, put them in a bag.
- Do not open toner containers forcibly while toner is inside, crush or squeeze them. Toner spillage can cause accidental ingestion or dirtying of clothes, hands, or floor.
