Photosensitive drum (opc)
2. Working principle: When OPC is exposed to charge and then contacted with toner, the toner will be absorbed and attached to the surface of the OPC due to the action of the electric field.
3. Note:The surface coating of the OPC is easily scratched and bruised;Keep the OPC away from direct sunlight and avoid long-term exposure of the fluorescent lamp.It is forbidden to hit the surface of the OPC with hard objects.
It is forbidden to directly touch the coating of the printing area of the OPC by hand to avoid leaving sweat and oil, these actions will result in poor print quality.
Primary charge roller (PCR)
2.Working principle: The PCR charges the surface of the OPC with a uniform charge.
3.Note:The PCR cannot be pressed against each other due to their structural reasons and will be deformed;
The surface of the PCR cannot be wiped with a solvent;Failure to use a hard object to collide during operation (eg, tweezers) will damage the surface of the PCR.
Magnetic roller (MR)
2. Working principle: According adsorption of toner by electric field and magnetic field.
3.Note:The MR should be placed away from other metal parts to avoid the impact of hard objects;The coated surface of the MR cannot be directly touched by hand, so as not to affect the printing quality;
Doctor blade (DB)
2.Working principle: Control the thickness of the toner layer on the magnetic roller(MR)/developing roller(DR) and assist the toner to be charged and charged.
The DB cannot be pressed against each other and are prone to deformation;
If the rubber powder DB is stored for too long, the rubber will become yellow and aging .
The metal powder DB should prevent extrusion and the steel sheet is deformed.
2. Working principle: The WB removes the residual carbon on the surface of the photosensitive drum after transfer.
3.Note:The WB cannot be pressed against each other and are prone to deformation;If the scraping knife is stored for too long, it will cause the rubber to become yellow and aging, and it will not be cleaned;
The wiper blade is not coated with lubricating powder during use, which will damage the drum core and cause the wiper blade to flip.
