Item
• The temperature of the Heating Roller Thermistor
/1 (TH1) goes down by a given level of degree
compared to the temperature of a given period of
time before when the paper passes on the Timing
Roller and blocks the Exit Sensor (PC2).
• The temperature of the Fusing Pressure Roller
Thermistor /1 (TH2) goes down by a given level of
degree compared to the temperature of a given
period of time before when the paper passes on
the Timing Roller and blocks the Exit Sensor
(PC2).
• The Polygon motor fails to turn stably even after
the lapse of a given period of time after activating
the Polygon motor.
• Motor Lock signal detects H for a given period
time consecutively during the Polygon motor is
rotating.
• SOS signal is not detected even after the lapse of
a given period of time after staring the laser out-
put.
• SOS signal is not detected for a given period of
time during printing or IDC sensor adjustment.
• No image data is output from the MFP Control
Board (PWB-MFP).
• The hardware involved with the compression
function offered by the MFP Control Board (PWB-
MFP) does not respond.
• The hardware involved with the extraction func-
tion offered by the MFP Control Board (PWB-
MFP) does not respond.
• The MFP Control Board (PWB-MFP) is faulty.
• The Motor Lock signal remains HIGH for a prede-
termined continuous period of time while the
Motor is turning.
• The Motor Lock signal remains LOW for a prede-
termined continuous period of time while the
Motor remains stationary.
