if the print quality is still acceptable, reset your drum unit by sticking on our reset chip. The procedure is very easy, takes 1 minute, full instructions are provided. <br /> <br />The chip will not fix any print defects, or improve print quality, it simply resets the drum unit back to zero so you can continue printing. <br /> <br />One chip required per drum unit. Chips can only be used to reset one drum unit. <br /> <br />http://www.zinetic.co.uk/intec_cp2020_drum_reset_chip-details.aspx
