To redistribute toner:

  2. Hold the cartridge over a sheet of paper to catch any loose toner, gently shake the cartridge.
  3. Reinsert the toner cartridge.

5.   

 Perform a stop test 

   

Stopping the paper part way through the printer can help identify where the problem is occurring.

To perform a stop test:
  1. Open the rear door.
  2. Print a single sided page.
  3. As soon as the paper comes in to view at the back of the printer, switch the power off to stop the paper part way through the fuser unit (heated rollers at the rear of the printer).

  4. Open the front cover, remove the toner and drum.

  5. Check the area of the page which has been printed but has not yet passed through the fuser unit.

If the problem is visible before the fuser unit replace the toner first, then the drum if you have not already done so.

If this does not resolve the problem, or the issue occurs only after the fuser, contact technical support for assistance
