E024

Description:
The developing assembly connector is disconnected.
The connection detection signal is absent continuously for 100 msec.
Remedy:
Replace the developing assembly toner sensor.
Re_Connect the connector.
Last resort: Replace the DC controller PCB.

--------

One problem found has been the toner sensor scraper blade in the developer not making contact with the surface of the toner sensor.
To check the toner sensor scraper blade first set up a work area.
Lay out several sheets of 11 x17 paper on the work surface. Disassembling the developer is a messy job. Remove the upper cover of the developer and then rotate the developer in a counter clock wise direction.

Basically the cylinder should rotate so the toner is scraped off of the cylinder by the developer blade.
If it is rotated in the wrong direction a large amount of toner will adhere to the developer cylinder and makes a mess.

The toner sensor is located on the on the outside of the developer and part of it goes through the wall of the developer unit.

Next look at the inside surface of the developer where the toner sensor is mounted while rotating the developer cylinder in the correct direction.

There is a mylar scraper sheet that needs to touch the inside surface of the developer wall.
If the blade is damaged or broken off the toner will not be cleaned off of the sensor and give the error code E024.
If the blade is the problem the developer will need to be replaced.
The part number for the developer is FM2-0287-010.
