2 ) . Put the paper feed cassette is not correct . Adjust the position of release paper ;
3 ) . Separation device is not working properly . Regulating the separating means ;
4 ) . Deformation or blocking the feed mechanism . Repair all parts of the tractor mechanism ;
5 ) . Guide plate attached to the toner and soiled . Clean the fixing guide plate ;
6 ) . The temperature sensor is not properly in contact with the fixing roller surface . Adjusting the temperature sensor (thermistor in contact with the fixing roller ) the correct position ;
7 ) . The fixing the bite amount ( heat roller ) so uneven width . Pressure maintenance and adjustment of the fixing roller ends ;
8 ) . On , make up about pressure roller uneven or have reached the limit of the number of sheets . Both ends of the pressure adjustment of the fixing roller , so as to achieve uniform ;
9 ) . The entire machine injustice . Change the installation place or location.
32, the abnormal rotation of the developing roller
Cause and Remedy :
This phenomenon is a problem with the developer , the process of copying the developing roller drive clutch armature coil has action, measure the voltage at both ends there , indicating that the circuit is good. Carefully observe the copying process is sometimes developing roller does not rotate , then it appears the White Pages or IOUs copy of the developing roller does not rotate the drum will not develop.
Remove the developer , the developer roller drive gear rotated by hand , as found very difficult, further examination revealed that the developer had been choked toner , developer roller rotating load is too large. Since the drive clutch is driven by torsion strength is not enough, so the above phenomenon , remove excess toner , toner volume adjustment under control , to fix this fault . In addition , the developer roller drive clutch wear itself will not move with the phenomenon , the printed copy is also true , should be replaced.
