Description: Printed draft is white (out of white paper)

Possible Reasons:

1. Generally, OPC does not conduct electricity, which may result in poor contact between the internal conductive sheet of OPC (one toner cartridge have been tested on the machine, and this probability is very small)
2. If it is a large proportion of the same defect, it is considered that the drum hub disk axle of the cartridge has poor contact with the internal conductive part of the printer, and it is not a product quality problem.It is necessary to check whether the conductive sheet inside the printer is dirty or deformed

Process 1: The problem stopped after replacing the new toner cartridge

Simple identification, direct compensation

Process 2: The problem still exsits after replacing the new toner cartridge
