[Phenomenon]
Service Code E11 is displayed on the operation panel when the machine

The following preventive actions are required when the development connector is
disconnected to protect the sensor from static electricity.
30mm
Preventive Actions:
1: Keep the connector at least 30mm away from the development unit when the unit is
cleaned using a vacuum cleaner.
2: Do not touch the pins of the connector when the development unit is carried away from
the main frame or cleaned.
Once Code E11 is displayed, the toner density sensor must be replaced with a new one.
Toner Density Sensor Replacement Procedure :
Please refer to sections 3.1 DEVELOPMENT UNIT REMOVAL and 3.3 TONER DENSITY
