How do I clean the drum unit?

Description of Solution 200000035326

The following is a procedure for cleaning the drum unit using either a medical alcohol swab (available at a local retail pharmacy or drugstore) or a cotton swab that has been lightly moistened with Isopropyl alcohol.


WARNING:  Isopropyl alcohol is flammable and should be kept away from fire or flame.


NOTE:  This cleaning process may have to be repeated several times to remove certain kinds of foreign material from the drum unit surface.  If the foreign material does not come off after several cleanings, the drum will require replacement.


1. Turn off the machine's power switch.  Disconnect all cables and cords and then unplug the power cord from the machine.


2.  Press the cover release button and open the front cover. Take out the drum unit and toner cartridge assembly.





NOTE: We recommend you put the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.


CAUTION: To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.



3.  Push down the blue lock lever and take the toner cartridge out of the drum unit.





NOTE: Handle the toner cartridge carefully.  If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.


CAUTION: To avoid print quality issues, DO NOT touch the shaded parts shown in the illustrations.




4.  Take a print sample and put it in front of the drum (See image below) to find the area of the drum that may be causing the print quality issue.





5.  Turn the drum unit gear toward you by hand and look for any marks or material on the drum surface (1).  Turning the drum gear will ensure you inspect the entire drum surface.





6.  When you find the area on the drum that matches the print sample, gently wipe the surface of the drum with the alcohol swab or cotton swab lightly moistened with isopropyl (rubbing) alcohol.  Allow the alcohol to evaporate or dry off the surface before continuing further.  Be sure to look over the entire drum as there may be several areas on a drum that need cleaning.



- The drum is photosensitive so DO NOT touch it with your fingers.

- DO NOT clean the surface of the photosensitive drum with a sharp object.

- DO NOT use a scrubbing or wiping motion because this might damage the drum.





7.  When you are done cleaning the drum, put the toner cartridge back into the drum unit until you hear it lock into place.  If you put the cartridge in properly, the blue lock lever will lift automatically.





8.  Put the drum and toner cartridge assembly back in the machine.





9.  Close the front cover.


10. Plug the power cord back into the machine and then reconnect all cables and cords.  Turn on the machine's power switch.


11. If you are experiencing a print quality issue, print a document and compare it to previous prints in order to see if the print quality has improved.


a.  If the issue is the same or the quality has improved, but the issue is still visible, you will need to repeat the cleaning process.  Multiple cleanings has been very successful in resolving print quality issues.


b.  If the print quality issue continues after multiple cleanings, the drum will need to be replaced.  The part number for the drum is DR600.  If you find that your retailer does not carry the specific supplies and accessories you are looking to locate, you can purchase them by calling our toll free Accessory Line on 1-877-552-MALL (6255) or shop on-line at our website at
