is not detected for 100 msec.)
The voltage of the power supply is faulty (high-
voltage error).
E064- While output is being generated, the AD value of the
0005 transfer output voltage is 0 (DEC) for 100 msec 2
times in sequence. (However, after output, it is not
detected for 100 msec.)
The BD interval is outside a specific range.
After the machine has become ready for image
E100-
formation (i.e., the scanner motor is ready for
0001
operation, and the laser has been turned on), an
error has occurred 50 times or more (BD error).
The scanner motor is faulty.
The scanner motor speed lock signal does not
E110-
0001 indicate a locked state a specific period of time after
the scanner motor has been started.
The scanner motor is faulty.
E110- The speed lock signal indicates a deviation 10 times
0002 in sequence at intervals of 10 msec after the signal
has indicated a locked state.
The scanner motor is faulty.
With the image clock switched over, the scanner
E110- motor speed lock signal does not indicate a locked
0003 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
There is an error in the communication with the high-
voltage power supply
E191-
The data transmission/reception does not end
0000
normally 500 msec after the most recent
transmission/reception of data ended normally.
There is an error in the detection of the CIS home
E202- position.
0001 The attempt to detect the home position fails when
the CIS is moved forward
There is an error in the detection of the CIS home
E202- position.
0002 The attempt to detect the home position fails when
the CIS is moved back.
The light intensity of the CIS is faulty.
E225-
During shading operation, the intensity is below a
0001
specific level.
