##322 [RX] Fixing heater temperature abnormality
Cause: Internal unit defect.
Solutions: (1) Check the connections between the fixing ass’y and the PCNT board (J206) and
between the fixing ass’y and the power supply unit (J102).
(2) Check the connection between the PCNT board (J101) and the power supply unit
(J202).
(3) Check the resistance between connector pins of the fixing ass’y.
J206-12 and J206-13: 436 to 301 kΩ (at 25°C)
J102-1 and J102-2: 25.1 to 28.8 Ω (at 25°C)
If either resistance is incorrect, replace the fixing ass’y.
(4) Replace the PCNT board.
(5) Replace the power supply unit.
(6) Replace the SCNT board.
##323 [RX] LASER/scanner section BD signal output abnormal
Cause: Internal unit defect (Low LASER intensity)
Solutions: (1) Check the connection between the LASER/scanner section (J801) and the SCNT
board (J5).
(2) Replace the LASER/scanner section.
(3) Replace the PCNT board.
(4) Replace the SCNT board.
Cause: Internal unit defect (BD signal timing error)
Solutions: (1) Check the connection between the LASER/scanner section (J801) and the SCNT
board (J5).
(2) Replace the LASER/scanner section.
(3) Replace the SCNT board.
##324 [RX] Printer section scanner motor rotation rate abnormal
Cause: Internal unit defect (Incorrect scanner motor speed)
Solutions: (1) Check the connection between the LASER/scanner section (J802) and the PCNT
board (J208).
(2) Replace the LASER/scanner section.
(3) Replace the PCNT board.
(4) Replace the SCNT board.
