Motor driver IC (IC401/IC802/IC803)The motor driver ICs control each motor in response to the commands from the CPU or the ASIC.d. Reset IC (IC1002)The reset IC monitors +3.3V voltage and resets the CPU and the ASIC when the power is turned ON.d. EEPROM(IC1007)The EEPROM stores various backup data.2.8.2.3 Fan/Motor Control 0013-8421/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller PCB serves to control 49 motors.The following shows the specifications of the various motors used in the machine:T-2-62.8.2.4 Drum motor failure detection 0013-8422/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller determines the drum motor failure and notifies the video controller of "E012 (The drum motor is faulty)", when it encounters the following con-ditions.1) Drum motor start-up abnormalityThe interval of the DRUM MOTOR SPEED signal does not settle the specified interval after 2.5 seconds of the drum motor drive start.2) Drum motor rotation abnormalityThe interval of the DRUM MOTOR SPEED signal stays irregular interval for 2 seconds and longer after once it has settle the specified interval.2.8.2.5 ETB motor failure detection 0013-8423/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller determines the ETB motor failure and notifies the video controller of "E012 (The ETB motor is faulty)", when it encounters the following con-ditions.1) ETB motor start-up abnormalityThe interval of the ETB MOTOR SPEED signal does not settle the specified interval after 3.5 seconds of the ETB motor drive start.2) ETB motor rotation abnormalityThe interval of the ETB MOTOR SPEED signal stays irregular interval for 2 seconds and longer after once it has settle the specified interval.2.8.2.6 Fixing motor failure detection 0013-8424/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller determines the fixing motor failure and notifies the video controller of "E014 (The fixing motor is faulty)", when it encounters the followingconditions.1) Fixing motor start-up abnormalityThe interval of the FIXING MOTOR SPEED signal does not settle the specified interval after 2.5 seconds of the fixing motor drive start.2) Fixing motor rotation abnormalityThe interval of the FIXING MOTOR SPEED signal stays irregular interval for 2 seconds and longer after once it has settle the specified interval.2.8.2.7 Exhaust fan failure detection 0013-8425/ i-SENSYS LBP5360 / i-SENSYS LBP5300The DC controller determines the exhaust fan failure and notifies the video controller of "E804 (The exhaust fan is faulty)", when the FAN LOCK signal is keptfor 10 seconds continuously.Name Purpose Type FailureDetectionMotorFeed motor(M4) To drive printer feed roller Stepping motor NoM drum motor(M6)To drive developing roller, Photosensitive drum, and stirrerplate DC motor YesC drum motor(M7)Y drum motor(M8)Bk drum motor(M9)ETB motor(M5) To drive ETB and transfer roller engagement/disengagement DC motor YesFixing motor(M1)To drive fixing pressure roller, delivery roller, developingroller, engagement/disengagement, and pressure rolleralienationDC motor YesDuplexing reverse motor(M11) To drive duplexing reverse roller Stepping motor NoDuplexing feed motor(M10) To drive duplexing feed roller Stepping motor NoFanExhaust fan(FM1) To exhaust heat from printer inside DC motor YesDuplex cooling fan(FM2) To exhaust heat duplexing unit DC motor Yes
