Causes:
Remedy: • Check that the printer is grounded properly. • Check that the connectors are connected to the controller board securely and correctly. • Check that the DIMM is connected to the controller board securely and correctly. • Power the printer off and on several times. • Check that the printer is not in electrically noisy environments.
Code: 100
Description: - Laser power has weakened. - SOS signal cannot be detected.
Causes: • ROS ASSY • PWBA MCU
Remedy: 1 Check after turning the power OFF and ON. Does the error recur even when the power is turned off and back on again? Go to Step [2]. End of procedure 2 Check the connection of the ROS ASSY Check the connection state between ROS ASSY and PWBA MCU. Are P/J151 and P/J12 connected correctly? Go to Step [3]. Reconnect the P/J151 and P/J12 correctly. 3 Check after replacing the ROS ASSY Replace the ROS ASSY with a new one. Does the error still occur after the replacement? Replace the PWBA MCU. End of procedure
Code: 1110 ... 2000
Description: 1110 ROM checksum error (bit 0 to 15) (font latter half) 1111 ROM checksum error (bit 16 to 31) (font latter half) 1120 ROM checksum error (bit 0 to 7) 1121 ROM checksum error (bit 8 to 15) 1122 ROM checksum error (bit 16 to 23) 1123 ROM checksum error (bit 24 to 31) 1170 Optional FONT ROM checksum error 1180 Optional ROM module A checksum error 1181 Optional ROM module B checksum error 1182 Optional ROM module C checksum error 1185 ROM module unsupported 1200 EEPROM writing error 1210 EEPROM writing times limit 1300 RTC failure 1400 Engine initialization error 1500 CCNV hardware error 1550 Initialization hardware error for SRAM for compression 1600 Video series hardware error (including PWMIC calibration error) 1610 Video series hardware error (VCNV error) 1700 Loopback test failure of network board 1702 Network board uninstalled 1710 Token Ring hardware error 1800 Illegal SPD 1999 Other hardware errors 2000 Software error
Causes:
Remedy: • Check that the printer is grounded properly. • Check that the connectors are connected to the controller board securely and correctly. • Check that the DIMM is connected to the controller board securely and correctly. • Power the printer off and on several times. • Check that the printer is not in electrically noisy environments.
Code: 300
Description: - Abnormal high temperature was detected - The printer detected that the circuit for the Temp sensor is in failure - Abnormal low temperature was detected - Warm-up has not completed within the specified time - The lamp remains lit longer than the specified time.
Causes: • FUSER UNIT • HARNESS ASSY FUSER • HARNESS ASSY LV TOP • LVPS • PWBA MCU
Remedy: 1 Check after turning the power OFF and ON. Does the error recur even when the power is turned off and back on again? Go to Step [2]. End of procedure 2 Check the installation of the FUSER UNIT Is the FUSER UNIT installed correctly? Go to Step [3]. Reinstall the FUSER UNIT. 3 Check the connection of the FUSER UNIT Check the connection state of the following items. • FUSER UNIT - PWBA MCU • FUSER UNIT - LVPS • LVPS - PWBA MCU Are P/J171, P/J17, P/J47, P/J14, and P/J501 connected correctly? Go to Step [4]. Reconnect P/J171, P/J17, P/J47, P/J14, and P/J501 correctly. 4 Check the continuity of the HARNESS ASSY FUSER Is there normal continuity between the following connectors? • P/J171 <=> P/J17 • P/J171 <=> P/J47 Go to Step [5]. Replace the HARNESS ASSY FUSER. 5 Check the continuity of the HARNESS ASSY LV TOP Is the continuity between P/J14 <=> P/J501 normal? Go to Step [6]. Replace the HARNESS ASSY LV TOP. 6 Check after replacing the FUSER UNIT Replace the FUSER UNIT with a new one. Does the error still occur after the replacement? Go to Step [7]. End of procedure 7 Check after replacing the LVPS Replace the LVPS with a new one. Does the error still occur after the replacement? Replace the PWBA MCU. End of procedure
Code: 500
Description: Abnormal rotation signal of Main/Sub/Deve Motor (DRIVE ASSY MAIN) or the PH Motor (DRIVE ASSY PH) is detected.
Causes: • DRIVE ASSY MAIN • DRIVE ASSY PH • HARNESS ASSY R SIDE • PWBA MCU
Remedy: 1 Check after turning the power OFF and ON. Does the error recur even when the power is turned off and back on again? Go to Step [2]. End of procedure 2 Check the operation of the Main Motor in the DRIVE ASSY MAIN Check the Main Motor with reference to FIP 2-7 . Was the trouble fixed? End of procedure Go to Step [3]. 3 Check the operation of the Sub Motor in the DRIVE ASSY MAIN Check the Sub Motor with reference to FIP 2-8 . Was the trouble fixed? End of procedure Go to Step [4]. 4 Check the operation of the Deve Motor in the DRIVE ASSY MAIN Check the Deve Motor with reference to FIP 2-9 . Was the trouble fixed? End of procedure Go to Step [5]. 5 Check the operation of the DRIVE ASSY PH Check the DRIVE ASSY PH with reference to FIP 2-6 .
