Trouble Code Description
C1300
Startup failure
• A LOW Polygon Motor (M2) Lock signal is not detected within a given period of
time that begins 1 sec. after the Polygon Motor has started turning.
Lock signal fault: Unstable after the first Lock signal has been detected
• For a period of 1 sec. after the first LOW Polygon Motor (M2) Lock signal (first
Lock) has been detected, the next LOW Polygon Motor Lock signal is not
detected.
Lock signal fault: Lock signal out-of-timing
• A LOW Polygon Motor (M2) Lock signal is not detected for a continuous given
period of time while the rotation of the Polygon Motor remains stabilized.
Faulty Lock signal
• A LOW Polygon Motor (M2) Lock signal is detected for a given period of time or
more when the Polygon Motor remains deenergized.
C13F0
Laser scanning system malfunction
• The SOS Sensor does not detect a rising edge of SOS within a given period of
time after the Polygon Motor (M2) has started turning and a laser output has
been started.
• The SOS Sensor detects no rising edges of SOS while VIA (image area con-
trol) is ON.
