Description: Drum phase adjustment abnormality: Drum phase sensors (Color drum phase sensor and K drum phase sensor) are not turned ON after the drum motor was rotated for a specified period of time.
Causes: Drum motor (K) Drum motor (YMC) K drum phase sensor Color drum phase sensor LGC board Cleaning blade (Y, M, C, K) Needle electrode Drum (Y, M, C, K)
Remedy: LGC board • Connector check (CN313, CN315) Drum motor (K) (M27) • Motor check (Perform the output check: 03-110) • Connector check • Harness check Drum motor (YMC) (M28) • Motor check (Perform the output check: 03-110) • Connector check • Driving section check (Is there any abnormality on the rotation?) • Harness check K drum phase sensor (S44) • Sensor check (Perform the input check: 03-[ALL]OFF/[9]/B) • Connector check • Harness check Color drum phase sensor (S43) • Sensor check (Perform the input check: 03-[ALL]OFF/[9]/A) • Connector check • Harness check Drum cleaner unit (Y, M, C, K) • Cleaning blade check (Check if it turns up.) Main charger unit • Needle electrode check Drum (Y, M, C, K) • Drum check (Check if the aluminum section of the drum flange is worn out.)
Code: CE90
Description: Drum thermistor-K abnormality: The output value of the drum thermistor-K is out of a specified range
Description: 2nd transfer roller position detection abnormality: The 2nd transfer roller does not contact/release normally.
Causes: 2nd transfer roller position detection sensor 2nd transfer cam motor LGC board
Remedy: 2nd transfer cam motor (M48) • 2nd transfer cam motor check (Perform the output check: 243) • Connector check • Harness check 2nd transfer roller position detection sensor (S50) • Sensor check (Perform the input check: 03-[ALL]OFF/[9]/[H]) • Connector check • Harness check LGC board • Connector check (CN307, CN314) • Board check 2nd transfer contact/release cam unit gear • Check that it is not damaged. Actuator in the TRU • Check that it is installed properly. • Check that it is not damaged. Sensors in the TRU • Check that they are installed properly. • Check that the cam is not damaged.
Code: CEC5
Description: Incorrect cam position alarm during 2nd transfer
Causes: Actuator in the TRU Sensors in the TRU
Remedy: 1 2nd transfer contact/release cam unit gear Check that it is not damaged. 2 Actuator in the TRU • Check that it is installed properly. • Check that it is not damaged. 3 Sensors in the TRU • Check that they are installed properly. • Check that the cam is not damaged. 4 If any abnormality on a part is detected and the part is replaced, the 2nd transfer pressure reduction is enabled by changing the value of the setting codes as follows: 08-4663: 0 to 10: Pressure reduction disabled1: Pressure reduction enabled 08-4664: 3 to 0Resetting incorrect cam position error count Notes: Change the value of the following codes to disable the pressure reduction: 08-4663: 1 to 0 0: Pressure reduction disabled 1: Pressure reduction enabled 08-4664: 0, 1 or 2 to 3 Resetting incorrect cam position error count
Code: CF10
Description: Communication module SRAM reading failure
Causes: Finisher control PC board Hole punch control PC board (when MJ-6102 is installed)
Remedy: Equipment • Is the error recovered when the power of the equipment is turned OFF and then back ON? Setting • Check if the MJ-1103/1104 is set as the specified finisher on the equipment. (08-1912=”1”) Finisher control PC board (FIN) • Connector check • Board check Hole punch control PC board (HP) • Connector check (when MJ-6102 is installed) • Board check
Code: CF90
Description: Laser optical unit shutter abnormality.
Remedy: Shutter motor (M38) Shutter • Motor check (Perform the output check: 03-201) • Connector check (CN213, CN214) • Harness check • Shutter plate check Shutter sensor (home position) (S24) • Sensor check (Perform the input check: 03-[ALL]OFF/[7]/[E]) • Connector check • Harness check Shutter sensor (end position) (S25) • Sensor check (Perform the input check: 03-[ALL]OFF/[7]/[D]) • Connector check • Harness check LGC board • Connector check (CN327) • +5V check (CN345-21pin) • Board check Other • Check if the equipment is grounded.
Code: CFA0
Description: Media sensor output abnormality before paper reaching: The sensor output value before paper is reached to the media sensor is not normal.
Causes: Media sensor (S69)
Remedy: 1 If these codes are recorded in the error history, the media sensor may have a malfunction. In this case check the following: 2 Is the connector of the media sensor disconnected or is any harness open circuited? 3 Are the arm of the media sensor and the bearing rollers operating properly? 4 Is the media sensor adjusted correctly? 6.7.1Adjustment of the media sensor position 5 If any abnormality was found in step 3 above or no abnormality was found in steps 2 and 4, replace the media sensor. Note that printing is available even if the media sensor is in a faulty condition. The functions that the media sensor usually performs are then carried out as follows: If the media type of paper is set as plain paper, a media type (plain paper 1 or 2) set in advance in the code below will be used. 08-4599 0: Plain paper 1 1: Plain paper 2 (Factory default - JPD: 0, overseas: 1) Media type setting checking function will be disabled. Even if the media sensor is in a faulty condition, any message notifying this will not be appear. Check the condition with the error history.
