Remedy: 1 <Color toner low density> Check the printing status. Is the color printing ratio 5% or more? Yes 2 No The color toner low density might be the cause. Turn the code 08-2692 "Prevention of color toner low density / ON/OFF setting" to ON, and then set number of sheets to be judged at the code 08- 2693 "Prevention of color toner low density/Judged number of sheets setting". 2 Developer unit • Check if the developer unit is installed properly. • Check that the developer unit and coupling on the equipment side are properly engaged. • Check that the mixer of the developer unit is rotated. • Check if the developer material is too light visually. • Check if the amount of the developer material is too large or too small. 3 EPU • Remove any toner or dust on the ATC sensor connector and the drawer connector of the process cover. • Remove any toner or dust on the EPU sensor connector and the drawer connector on the equipment side. 4 Auto toner sensor Harness LGC board • Check the connectors and harnesses between the auto toner sensor and LGC board (CN340). • Check if there is any foreign matter such as toner in the connector of the auto toner sensor. Remove if there is and reconnect it.

Code: C411
Description: Thermistor or heater lamp abnormality at power-ON: Abnormality of the thermistor is detected when power is turned ON or the temperature of the fuser roller does not rise in a specified period of time after power is turned ON.
Causes: Power supply unit. LGC board
Remedy: Power voltage Check if the power voltage is normal.(Is the voltage during the operation ±10% of the rated voltage?) Thermopiles • Check if the fuser belt center and side thermopiles (front, rear) are installed properly. • Check if the harnesses of the fuser belt center and side thermopiles (front, rear) are open circuited. Power supply unit and fuser unit • Is the fuser unit installed correctly? • Check if the heater lamp is broken. • Check if the connector of the heater lamp is disconnected. • Check if the thermostat is blown • Check if the connectors of the power supply unit are disconnected (power supply unit AC output connector CN408, CN409 and LGC I/F connector CN404 CN405). • Check if the power supply unit is abnormal. LGC board • Check if the connectors CN333, CN345 and CN361 are disconnected. • Check if the conductor pattern on the LGC board is short circuited or open circuited. Status counter After repairing the matter which caused the error [C411/C412], perform the following: • Turn ON the power while [0] and [8] are pressed simultaneously • Key in “2002”, then press [START]. • Change the current status counter value “1 “ or “2 “ to “0”, then press [OK] or [INTERRUPT] (to cancel [C411/C412]). • Turn the power OFF and then back ON. Make sure that the equipment enters the normal ready state.
