Preparation for filling:
Before you melt the filling opening into the cartridge, you have to remove the label as shown on 1 picture. Then take the hot soldering iron and melt the filler opening as shown in Figure 2. After melting the opening, take care to cleanly deburr the opening. Please make sure that no plastic shavings get into the cartridge. These plastic shavings will damage the printing mechanism of the toner cartridge and could deteriorate the printed image.

Before you fill the toner cartridge, you have to remove the old toner that is still present. Make sure you do it in the fresh air. Due to different properties between new and existing toners, the mixed toner can clump together. Shake the remaining toner into a tight plastic bag.

Safety note for handling refill toner:
Toner powder can be harmful if improperly handled. We expressly recommend the use of breathing apparatus when filling the toner cartridge. In addition, carbon powders are extremely flammable in a suitable mixture of oxygen. Also, be careful not to touch the photosensitive drum or expose it to direct sunlight. This can lead to incorrect printouts. Eurotone assumes no responsibility for the success or failure of the procedure described
