• Code: 352
• Description: Toner bottle motor error: K. If the error flag occurs for a toner bottle motor 5 times, the machine issues this SC. This error flag is calculated as follows. • The error flag of the toner bottle motor is made when the machine detects a LOCK signal of the toner bottle motor for 0.9 seconds during the toner bottle motor rotating (1 second). • The error flag of the toner bottle motor is cleared when the machine detects a LOCK signal of the toner bottle motor less than 0.9 seconds during the toner bottle motor rotating (1 second).
• Causes: • Solidified toner in the toner bottle • Toner supply tube bent • Incorrect setting of the toner bottle • Broken toner bottle
• Remedy: 1. Shake the toner bottle five or six times. 2. Check if the toner supply tube to sub-hopper unit is bent. 3. Check and reinstall the toner bottle. 4. Replace the toner bottle.
