Solution

1. Open Door B.

   • For single-function printers
   
   • For multifunction products
   


2. Remove the waste toner bottle (WTB).

   


3. Unplug the green cable.

   


4. Remove the imaging kit. Pull the unit out of the device and set on flat surface.

   


5. Unlock the DHDA (developer hold down arm) by turning both blue levers; this disengages the 4 Imaging Units (developer unit and photoconductor).

   


6. Inspect the developer unit to make sure all levers are in the closed position and all contacts don’t have any damage.

   


7. Reinstall the imaging kit and plug in the green cable.

   


8. Insert the waste toner bottle then close Door A and Door B.

   
   


9. Perform a test print and check if the issue persists.
