Description: Drum phase adjustment abnormality: Drum phase sensors (Color drum phase sensor (S43) and K drum phase sensor (S44)) are not turned ON after the drum motor was rotated for a specified period of time.
Causes: Drum motor (M10) Drum drive unit • Color drum phase sensor (S43) • K drum phase sensor (S44) LGC board
Remedy: 1 • Is the error cleared after the power is turned OFF and then back ON? • Is the drum motor (M10) operating properly? (Perform the output check: ON 03-101 / OFF 03-151.) * Check the operation after removing all process units (EPU (Y, M, C, K)). Yes 5 No 2 2 Drum motor (M10) Connector check 3 Drum drive unit Check if their drive gears are damaged or if they contact with the equipment. Correct if any. 4 LGC board • Connector check (CN332) • Board check 5 Rotate the drum of each EPU in the direction of the arrow once. (See the figure below.) If the rotation of the drum is extremely heavy or not smooth, check if the mechanism of the EPU is normal. Fig. 8-1 6 Rotate the drum with 03-101. Are the drum phase sensors (Color drum phase sensor (S43) and K drum phase sensor (S44)) are operating properly? (Perform the input check: Color 03-[ALL]OFF/[1]/[F] K 03-[ALL]OFF/[1]/[E].) Yes 9 No 7 7 Drum phase sensor • Check the connector of the drum phase sensors (S43, S44) and joint connectors • Check if there is any foreign matter such as grease in the detection area of the drum phase sensors (S43, S44). 8 LGC board • Connector check (CN332) • Board check 9 Drum drive unit Check if the drive gears are installed properly. (Check if the mark on each gear is aligned with the area of the punched mark on the frame.) 10 Actuator Check if the actuator is installed properly. 11 LGC board Board check CE71 error can be prevented by setting the drum phase adjustment control OFF in the self-diagnostic code below. The setting value shall be returned after the recovery, otherwise color deviation increases. Drum phase adjustment control ON/OFF code 08-4766 0: Disabled 1: Enabled (Default)

Description: Drum thermistor-K abnormality: The output value of the drum thermistor-K is out of a specified range.
Causes: Drum thermistor K LGC board
Remedy: Drum thermistor Connector and harness check of drum thermistor K LGC board • Check the harnesses between the LGC board and the drawer connector for developer unit. • Connector check (CN340)

Description: 2nd transfer roller releasing position detection abnormality
Causes: Registration motor (M19) LGC board One-way clutch gear at the end of the shaft 2nd transfer roller position detection sensor (S29)
Remedy: 1 Is the 2nd transfer roller's contact and release proper? (Perform output check: 03-239) Yes 9 No 2 2 Is the registration motor (M19) rotating? Yes 5 No 3 3 Registration motor (M19) • Connector check • Harness check 4 LGC board • Connector check (CN332) • Board check 5 Is the 2nd transfer roller holding arm operated smoothly when it is pushed? Yes 8 No 6 6 2nd transfer roller pressure spring Check that the spring is installed properly (not running off the frame of the mold). 7 Parts surrounding the 2nd transfer roller Check if there is any damage or abnormality. 8 One-way clutch gear at the end of the shaft Replace it. 9 Is the 2nd transfer roller position detection sensor (S29) working properly? (Perform input check: 03-[ALL]OFF/[7]/[E]) Yes No 10 10 LGC board • Connector and relay connector check • Harness check 11 Parts surrounding the 2nd transfer roller • Connector check (CN337) • Board check 12 Mechanical section Sensor check 13 LGC board Board check
