##322 [TX/RX] Fixing heater temperature abnormality
Cause: Internal unit defect.
Solutions: (1) Check the connections between the fixing ass’y and the PCNT board (J2) and
between the fixing ass’y and the power supply unit (J102).
(2) Check the connection between the PCNT board (J403) and the power supply unit
(J202).
(3) Check the resistance between connector pins of the fixing ass’y.
J203-12 and J203-13: 790 to 212 ký (at 10 ~ 35°C)
J102-1 and J102-2: 120.9 to 139.1 ý (at 25°C)
If either resistance is incorrect, replace the fixing ass’y.
(4) Check the voltage at J102 of the power supply unit (with the heater cable TB1
removed); if it is not the same as the AC input voltage, replace the power supply
unit.
(5) Replace the PCNT board.
(6) Replace the SCNT board.
