How to clean the photoconductor unit; The photoconductor unit (also referred to as the PC kit) is the most likely cause of print quality problems.


In most cases, you will have to replace the photoconductor unit to fix a print quality problem. However, you can also try cleaning the photoconductor drum. If the problem is being caused by excess toner accumulating on the roller, cleaning the photoconductor drum will resolve it.

The photoconductor unit is located on the right-hand side of the printer under the right cover near the top of the printer. This cover is also referred to as Door C. See image below.

To examine and clean the photoconductor unit

  1. Remove the photoconductor unit by grabbing the two green handles/hooks (shown above) and pulling the photoconductor straight out.

  2. Place the photoconductor on a flat surface. We recommend placing a sheet of paper or newspaper under the photoconductor to catch any loose toner that may fall off it.  

  3. Open the shutter and examine the photoconductor drum. The photoconductor drum is  the green (sometimes blue) roller inside the photoconductor unit (B in the image below). There is a black plastic shutter/door (A) covering the drum. Caution! The photoconductor drum is sensitive to light, especially sunlight. Do not expose it to light any longer than is necessary. 


  4. Inspect the photoconductor drum for any toner or dust.

    • If the drum is clean, skip ahead to Step 5.

    • If the drum is not clean, try cleaning it with a dry lint-free cloth or tissue. Caution: Avoid using a paper towel as that may cause tiny scratches to appear on the drum. Also avoid touching the drum with your fingers as that can leave a permanent fingerprint on the drum.

      • If cleaning the photoconductor drum clears up the spots completely, continue using the printer.

      • If the spots begin to clear up but do not entirely go away, remove the photoconductor unit and try cleaning the drum again. Only one-third of the drum can be seen from behind the protective shutter. You should be able to get the entire drum cleaned after letting the printer turn the photoconductor drum, but this may require multiple cleaning attempts (about three or four).

      • If the problem continues, you probably have a leaking or otherwise defective photoconductor unit. It will need to be replaced.

  5. Examine the photoconductor drum for any damage.

    • If the photoconductor drum is not damaged, skip ahead to Step 6.

    • If the photoconductor drum is damaged, check to see if the marks on the drum look the same as the marks on the page. If they are the same, the photoconductor is the likely cause of the problem and will need to be replaced.

    • If the photoconductor is damaged but the marks on the drum do not look the same as the ones on the printouts, the photoconductor unit should still be replaced. However, another part in the printer may be causing your particular print quality problem.  

  6. While you have the right side cover of the printer open, look inside the printer. Check to see if any toner has piled up anywhere in the printer or on any of the rollers. If you see an accumulation of toner anywhere, try cleaning it up.

  7. Reinstall the photoconductor unit into the printer and close the side door.

  8. Try printing again.

  9. If the print quality problem is not resolved, parts on the printer other than the photoconductor unit may be causing the problem. For information on other items and settings you can check, click here.


When replacing the photoconductor unit, please be aware that the counter on the printer is reset whenever you install a new photoconductor unit. As a result, you will lose all the unused pages on the old one. This does not occur when you install an old or used photoconductor.
If you have access to a used photoconductor unit (for example, one from another Optra W810 printer), try installing it in the printer first.

  • If installing a used photoconductor clears up the problem, you will know that the original photoconductor needs to be cleaned or replaced.

  • If changing the photoconductor does not fix the problem, the PC kit counter will not be reset and you will not lose any unused pages from the old photoconductor.
