Plastic cover for laser cartridges in Brother printers

Mag Roller contains two parts:

- magnetic core,
- cover of core.

These two parts are equally important in process of transferring toner molecules to OPC Drum. Foreshadowed cover of core causes irregular distribution of toner molecules on its surface, and that is the reason of creating some disturbances on printout like:

- too bright printout partly or totally,
- stains on printout or bright empty spaces.

Mag Roller plastic cover prevent scratches on core´s cover, which can appear during transport of cartridge. Regenerated cartridge with installed cover looks very esthetically.
