When using the laser toner cartridge, please pay attention to the following:

• Toner inside the laser toner cartridge is combustible. Please do not put the laser toner cartridge near any source of ignition, so as to avoid causing a fire.

• When removing or disassembling the laser toner cartridge, please pay attention to the toner leakage problem. In case of the toner leakage resulting in that the toner contacts with your skin or splashes into your eyes and mouth, please immediately wash with clear water, and consult a doctor immediately if you feel unwell.

• When placing the laser toner cartridge, please keep it away from the area reachable by children.

2. Service Life of the Laser Toner Cartridge

Service life of the laser toner cartridge depends on the amount of toner that print jobs require.

When the printer's LED indicator shows the status in the following figure or the LCD display shows "Ctg life expired", it indicates that the laser toner cartridge life has expired and needs to be replaced.

8.2.2. Replace Laser Toner Cartridge

| Note: | Before replacing the laser toner cartridge, please pay attention to the following: • The laser toner cartridge surface may have toner. Please remove it carefully to avoid spilling. • Put the removed laser toner cartridge on a piece of paper to avoid the toner from accidentally spilling. • After removing the protective cover, please immediately install the laser toner cartridge into the printer, so as to avoid photosensitive drum damage caused by exposing to too much direct sunlight or indoor light. • When installing the laser toner cartridge, do not touch the surface of the photosensitive drum so as not to scratch it.

The steps of replacing the laser toner cartridge are shown below:

1. Turn off the printer.

2. Open the front cover, and remove the empty laser toner cartridge along the guides.

3. Open the package of a new laser toner cartridge, hold the handle of the cartridge and gently shake around 5-6 times, so as to make the toner evenly distributed inside the cartridge.

4. Remove the protective cover, and put the laser toner cartridge into the printer along the guides, and close the cover tightly.

| Note: | • Check whether there is any seal before installing the toner cartridge into the printer; if there is any, please tear off the seal and then install the cartridge.
