Code Cause
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.
