4 ) . Supply voltage extreme instability.

42 , the operation panel displays all the lights go out after a while

Cause and Remedy :

This phenomenon occurred in self- protection function latching power switch copiers , probably due to :

1 ) The power supply voltage is extremely unstable .

2 ) . Dayong electrical work nearby.

3 ) . Individual power supply circuit is decreased thermal stability of the main components .

43 , after the copy button is pressed, the main motor is constantly turning , and no other copy action

Cause and Remedy :

Main motor driven by a clock pulse generator ( also known as an encoder ) photoelectric breaker or LED light tube clogging , CDS photoresistor damage , which can not generate a clock pulse signal is input to the CPU, making it impossible to enter the Copy Control Program .

44 , the machine pollution

Cause

1 ) . Are a lot of dust in the surrounding environment ;

2 ) . Machine maintenance work is good ;

3 ) . Are all the air filter should be cleaned or replaced ;

4 ) . Whether drum or carrier has fatigue ;

5 ) . For the amount of powder is inappropriate or carrier volume has enough ;

6 ) . Indian efficiency is low or cleaning system is working well.

45 , maintenance call lights

Cause and Remedy :
