1. Avoid using and storing in high humidity, high temperature, and high cold environments. If the toner cartridge is stored in a relatively high temperature or relatively cold place for too long, it should be restored to room temperature for 2-3 hours before use. (The most ideal working temperature: 15-25℃, working relative humidity: 20-80%)
2. Do not tear off the seal of the toner cartridge before use, otherwise the toner will clump once it is damp, affecting the printing effect or causing the printing color to be light.
3. Avoid exposing the toner cartridge to strong light for a long time. Do not tear off the plastic bag of the toner cartridge when it is not in use, especially do not open the photosensitive drum light shield on the toner cartridge casually. If it is continuously exposed to strong light for more than ten minutes, the photosensitive drum may be damaged.
4. When replacing the toner cartridge, it is best to use a vacuum cleaner to clean the place where the toner cartridge is placed in the machine, and use a soft cloth to clean the accumulated paper scraps and toner on the paper path. The exposed electrical contact piece can be wiped with a cotton swab dipped in alcohol to maintain good electrical contact.
5. Do not rotate the OPC drum core by hand without authorization. Be sure to pay attention to the direction when rotating the OPC drum core. If the rotation direction is incorrect, it will damage the parts and cause powder leakage or printing stains during printing.
