Item
• An EEPROM where no initial data is written is
detected.
• The image transfer voltage exceeds 100 V for
the set period of time while the IU Motor remains
stopped.
• The Fusing Roller Thermistor does not detect
the required temperature within 30 sec. after a
warmup cycle has begun; therefore, the copier
does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.
• The Fusing Roller Sub Thermistor does not
detect the required temperature within 30 sec.
after a warm-up cycle has begun; therefore, the
copier does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.
• The Fusing Roller Thermistor and Fusing Roller
Sub Thermistor are detected to be at a tempera-
ture above 240 °C when the Main Power Switch
is set to ON.
• The Fusing Roller Thermistor and Fusing Roller
Sub Thermistor are detected to be at a tempera-
ture below 105 °C during standby.
• The Fusing Roller Thermistor and Fusing Roller
Sub Thermistor are detected to be at a tempera-
ture below 105 °C during printing.
• Communications with the Mechanical Control
Board and the MFBS Board fail.
• No SOS falling edges are detected within the set
period of time after laser emission began while
the Polygon Motor is turning.
• No SOS falling edges are detected while VIA
remains ON.
• The Polygon Motor Lock signal could not be
detected within the set period of time after the
Polygon Motor is energized. (Faulty start detec-
tion)
• No First Lock signals are detected during the 1-
second period that starts 1 second after a First
Lock signal. (Faulty lock signal detection)
• The Polygon Motor Lock signal could not be
detected after the set period of time has elapsed
while the Polygon Motor is turning. (Out-of-timing
lock detection)
• The Polygon Motor Lock signal is set to ON for
longer than the set period of time while the Poly-
gon Motor remains stopped. (Abnormal lock
detection)
