| Fault phenomenon | Fault cause | Solution |
| Ejector leakage | Dust inside the ejector | Cyclic test of the ejector |
| ejector has been damaged | Replace ejector | |
| Ejector fails to operate. | Poor contact between the plug behind ejector and the socket | Re-plug, repair the poor contact position |
| Disconnection occurred to the valve core | Replace the ejector | |
| Color sort board has been damaged | Replace color sort board | |
| Ejector with small spray volume | Dust inside the ejector | Cyclic high frequency test of the ejector |
| Low air pressure | Check pressure gauge and relevant air circuit | |
| Material flying | Big difference in temperature between the material and the material chute | Adjust temperature of the chute to approximate that of the material. |
| Dust agglomeration | Clean the chute with soft cloth | |
| Chute with scratch | Sand papering or replace it | |
| Frequent operation for solenoid valve | Wrong ejector | Correctly select sort mode |
| Position of background plate not properly set | Readjust background plate | |
| No color separation | Low sensitivity | Readjust sensitivity |
| haven't been power on | Power on the solenoid valve power supply | |
| Poor Color Separation Effect | Dust on the sorting glass | Remove dust manually or by soft cloth |
| Incomplete for the color sorter | Check or replace rubber strip | |
| Poor Separation Effect of Complete Machine Side | Incomplete or poor ash removing for the rodless cylinder | Adjust ash wiper and the ash wiping speed |
| Color sorter stops working frequently | High sensitivity | Readjust the sensitivity |
| Improper adjustment of background plate | Readjust the background plate | |
| Raw material with high quantity of impurity | Reduce the yield | |
| Color sorter is under pressure | Check pressure; readjust if the gas circuit is too far away from the sorter | |
| Frequent pressure protection | Clean and open the pipeline by cleaning or replacing the filter element | |
| Motor three-phase winding is damaged | Replace the motor | |
| A.C. contactor damaged or poor contact | Maintain or replace A.C. Contactor | |
| Thermorelay damaged or poor contact | Maintain or replace thermorelay | |
| 380V power supply phase shortage | Maintain charging line | |
