Code Cause
0002 While output is being generated, the AD
value of the primary DC voltage is 230
(DEC) or more for 100 msec 2 times in
sequence. (However, after output, it is
not detected for 100 msec.)
0003 While output is being generated, the AD
value of the developing DC voltage is
224 (DEC) or more for 10 msec 2 times
in sequence. (However, after output, it is
not detected for 100 msec.)
0004 While output is being generated, the AD
value of the transfer output current is 205
(DEC) or more for 100 msec 2 times in
sequence. (However, after output, it is
not detected for 100 msec.)
0005 While output is being generated, the AD
value of the transfer output voltage is 0
(DEC) for 100 msec 2 times in sequence.
(However, after output, it is not detected
for 100 msec.)
E100 The BD interval is outside a specific range.
0001 After the machine has become ready for
image formation (i.e., the scanner motor
is ready for operation, and the laser has
been turned on), an error has occurred 50
times or more (BD error).
E110 The scanner motor is faulty.
0001 The scanner motor speed lock signal does
not indicate a locked state a specific
period of time after the scanner motor has
been started.
0002 The speed lock signal indicates a
deviation 10 times in sequence at
intervals of 10 msec after the signal has
indicated a locked state.
0003 With the image clock switched over, the
scanner motor speed lock signal does not
indicate a locked state 6.5 sec after a
switchover is made from low to normal
speed or 8 sec after a switchover is made
from normal to low speed.
