The Mag Roller Sleeve- MRS Imaging Supply is the most important component for producing solid print density. As the Mag Roller Sleeve rotates the magnetic toner is attracted by the permanent magnet located at the centre of the MRS. As a result, the toner powder gets properly charged, resulting into increased image density. As the Mag Roller wears, it loses its ability to properly charge toner and results in decreasing imaging density [light prints]. The Mag Roller Sleeves restore uniform print quality, reliable, consistent performance good for 5 cycles.
