2 ) Open the copier cover , find power line fuse ( typically 10A or 15A) power switch to turn off the copier , with a pen to poke fuse . Check with a multimeter ohm fuse is broken , if not broken , check the AC power supply circuit diagram according to the aircraft systems ; if broken, replace the same length and the nominal value of the fuse . If the replacement insurance, continue to be blown , the power circuit has shorted place. At this point , you need to thoroughly check the power circuit , short circuit to find out why. In addition to these inspection methods , but also taking into account the characteristics of the model itself , such as : NP - 400 repair master switch SW1 is turned on , EP - 450Z front door and down the body , or whether Hao , U - Bix3300MR fixing whether the plug is good, whether the insurance fuser lamps heat off, and so on.
36 , after the fixing wrinkles copy output
Cause and Remedy :
1 ) . Heat roller or rubber roller Complex ; complex shape or surface coating off
2 ) . Fuser roller uneven pressure ;
3 ) . Fuser temperature is too high ;
4 ) . Copy paper damp.
37 , electrostatic copier separation failure
Cause and Remedy :
Separation mechanism is a common fault separation failure , causing jams. Separation failure causes are:
1 ) . Separation claw separation device , mostly due to the electromagnet action at the wrong time , or electric iron does not work , and the separation claw stuck, inflexible action caused by other reasons ;
2 ) . When separating belt separation, due to the separation zone fracture or low vacuum suction box , copy paper does not suck down ;
3 ) . When the electrode separation separation, due to the separation of high-pressure or low output , and wire contamination , separate current decreases, the separation can cause failure ;
4 ) . Feeding is not normal, a double or more sheets . Making the separation mechanism is not working properly , causing paper jams ; or paper jam in the cleaning device , scratch the surface of the photoconductive layer ;
