The charge roller is what cleans and charges the surface of the drum before printing. If the rollers get contaminated typical signs are vertical grey areas or back ground in certain parts of the page. In worse case scenarios it can lead to totally black pages. Usually, if you are experiencing print quality issues I first try the toner cartridge, inspect the fuser, and check the charge roller. More often than not, most my print quality issues on these machines stem from toner or charge roller issues. In most cases a third party toner has contaminated the charge roller. Also, companies sell third party charge rollers. Personally, I feel that I get more life out of the OEM charge rollers and experience less print quality issues with them. Therefore, I recommend to buy OEM charge rollers to save some frustration and more frequent repairs on your office equipment.

Note : It might be easier to remove the charge roller if you slightly lower the top cover door. This will lower the arms that hold the charge roller in place, making it easier to separate the roller post from the holder. Careful that you don’t bend the holders to far as they can break.
