ERROR CODE
E-4
E014
Main cause The belt motor (M15) is faulty. The belt motor drive system has an excess
load. The drum drive AC generation PCB is faulty. The transfer drive AC
generation PCB is faulty. The DC controller PCB is faulty.
Condition of
detection
0001 The target speed cannot be attained even when the frequency of the
motor drive pulse is increased to the upper limit.
0002 The target speed cannot be attained even when the frequency of the
motor drive pulse is decreased to the lower limit.
0003 The encoder signal is not generated by the motor.
0004 The motor rotates in the direction opposite the desired direction.
0005 Not used.
0006 The target speed cannot be attained even when the frequency of the
motor drive pulse is changed.
0007 Not used.
0008 Not used.
0009 An error has occurred in the communication with the DC controller
PCB.
E020
Main cause The ATR sensor connector is disconnected. The developing cylinder/stirring
screw fails to rotate.
Condition of
detection
XX=01: Y, XX=02: M, XX=03: C, XX=04: Bk (XX indicates the develop-
ing assembly color)
XXA0 During printing sequence, the difference between the maximum
value and the minimum value of SIGNAL (9 samplings) is 0.2 V
(10) or less.
Main cause The RAM data inside the drum unit is faulty.
Condition of
detection
XX=01: Y, XX=02: M, XX=03: C, XX=04: Bk (XX indicates the develop-
ing assembly color)
XX80 During printing sequence, the value of INIT-SIGNAL entered as
part of initial settings has dropped to 2.344 V (120) or lower.
XX81 During printing sequence, the value of INIT-SIGNAL entered as
part of initial settings has risen to 2.656 V (136) or higher.
XX90 During printing sequence, the correction value for INIT-SIGNAL
has changed to 0 (in service mode, ADJUST>DENS>SIGG-Y/M/
C/K).
