2. Check the TD sensor values of SP3-210, respectively: K (3.25), C (1.92), M (3.31), Y (2.04), and judge the magenta in the powder-deficient state by numerical observation;

 

3. Execute SP3-050-5 to help the magenta force to replenish the toner. After the execution, the SC361-03 code appears on the machine, as shown in the figure:

4. After the SP3-030-5 magenta TD sensor is initialized, the machine is normal, and SP3-050-5 forced refilling is performed again;

5. Review the TD sensor values of SP3-210 again: K(3.25), C(1.92), M(1.82), Y(2.04);

6. Execute Print SP 1-103-2 print test sample image, the image returns to normal;
