Copying, printing often occurs the bottom ash phenomenon, generally occurs in the copying 6-100,000 cycles, replace the carrier, clean the developing magnetic roller is normal, but copying about 2-10 million, and the bottom ash phenomenon will occur.
The frequency at which the fault occurred is uncertain!
1. When the fault occurs, the TD sensor is not within the standard value.
2, the copy paper is defective, use too much acid paper or paper powder.
3. The ID parameter is incorrect and the toner density cannot be controlled.
4, the toner chargeability decreases, causing bottom ash.
Since the bottom ash occurs, there are many reasons for this....
