L1 00
Feeding is not completed within
the specified time after starting
feeding. When the mirror base is returned for the specified time (6 sec) in mirror initializing
after turning on the power, the mirror home position sensor (MHPS) does not turn
OFF. Or when the mirror base is fed for the specified time (about 6 sec) after start of
copy return, the mirror home position sensor (MHPS) does not turn OFF.
L3 00
Return is not completed within the
specified time. When the mirror base is returned for the specified time (6 sec) in mirror initializing
after turning on the power, the mirror home position sensor (MHPS) does not turn
ON.Or when the mirror base is returned for the specified time (about 6 sec) after start
of copy return, the mirror home position sensor (MHPS) does not turn ON.
L4 01 Main motor lock When the main motor encoder pulse is not detected for 100msec.
L6 10
Polygon motor lock The lock signal (specified rpm signal) does not return within a certain time (about
20sec) from starting the polygon motor rotation
H2 00 Thermistor open detection The fusing thermistor is open.
H3 00
Heat roller abnormally high
temperature The fusing temperature rises above 240˚C.
H4 00
Heat roller abnormally low
temperature The fusing temperature does not reach 185˚C within 27 sec of turning on the power,
or the fusing temperature keeps at 140˚C.
U2 01 Counter sum check error When the counter check sum value stored in the EEPROM is abnormal.
U2 04
EEPROM serial communication
error When a communication trouble occurs with the EEPROM.
U2 40 CRUM IC Serial communication error when a communication trouble occurs with the CRUM IC.
F2 04 Toner cartridge type error When a toner cartridge of different type is used.
F6 80
Communication trouble with FAX
PWB (Protocol) Error in data reception from the FAX board to the MCU.
Occurs when the message header of the message format is other than F.
Cancel method: Turn OFF/ON the power.
F6 81
Communication trouble with FAX
PWB (Parity) Error in data reception from the FAX board to the MCU.
Occurs when the odd number parity set with SMR (serial mode register) differs from
the reception data.
Cancel method: Turn OFF/ON the power.
F6 82
Communication trouble with FAX
PWB (Overrun) Error in data reception from the FAX board to the MCU
Occurs when the next data reception is completed with RDRF (Receive Data Register
Full) flag of SS (Reserial status register) set to 1.
Cancel method: Turn OFF/ON the power.
F6 84
Communication trouble with FAX
PWB (Framing) Error in data reception from the FAX board to the MCU.
Occurs when the stop bit is 0. (The stop bit must be 1.)
Cancel method: Turn OFF/ON the power.
F6 88
Communication trouble with FAX
PWB (Time-out) Occurs when time is out without response in data communication between the FAX
board and the MCU.
Cancel method: Turn OFF/ON the power.
F6 10
FAX PWB trouble Communication trouble between the MCU and the FAX board or between the FAX
board and the FAX panel
Cancel method: Turn OFF/ON the power. Check connections.
