Clean both the Q1010 and Q1009 Sensor, beginning with the Q1010 Sensor.

WARNING: The surrounding area of the machine around the sensors can be extremely hot!

Cleaning the Q1010 Sensor:

  1. Open the Processor Doors. The handle to open the doors is above Paper Tray 1.

  2. Behind the left Processor Door, just to the left of Paper Tray 1, is a large green handle. Pull on the handle and pull out the Fuser Module.



  3. Locate the CAUTION label on top of the Fuser Module.

  4. Approximately 25 mm (1 inch) to the left of the label is a small U-shaped cutout in the aluminum frame and a tiny square mirror the size of your small fingernail.



  5. Use a cotton swab to clean this mirror and the small plastic sensor to the right of the mirror. Make sure you do not touch the hot surfaces in this area.




    If the mirror is covered with fuser oil, you may need to use a small amount of Lens and Mirror Cleaner, then follow up using a clean cotton swab.

Cleaning the Q1009 Sensor:

  1. To the left of Paper Tray 1, at the back of the Fuser Module, locate the area 7 label on the machine frame.

  2. Look inside the cutout area. You may need to kneel down so you can see inside the cutout. To your left is a clear plastic bottle containing Fuser Agent. Inside the cutout, and coming out on the side of the plastic bottle, is a shiny metal tab. The right surface near the top of that tab is a mirror. About 10 mm (3/8 of an inch) to the right, facing the mirror, is the Q1009 sensor.



  3. Clean the mirror and sensor with a small amount of Lens and Mirror Cleaner on a soft, lint-free cloth.



  4. Push the Fuser Module firmly back into the machine.

  5. Close the Processor Doors.
