FS-6020
1-5-3
(1-1) Error code 2000 [E1] (main motor error)
Detection conditions
• The main motor ready signal (MOTRDYN) does not become ready (low level) a specified time after the main motor drive
signal (MOTONN) is turned on.
• The main motor ready signal (MOTRDYN) does not become ready (low level) a specified time after the main motor drive
signal (MOTONN) is turned off.
Corrective measures
Is there any damage to
the harness (S02814) between
the engine/high voltage PWB and the
main motor or improper connection at the
YC12 connector on the
engine/high-voltage
PWB?
Is the voltage at
pin No. 1 (+24V3) of
the main motor connector DC
24 V in the printer
standby mode?
Does the level at
pin No. 3 (MOTONN) of
the main motor connector change
from H to L in synchronization
with activation of the
motor?
Does the level at pin
No. 4 (MOTRDYN) of the
main motor connector change from H to
L after activation of the motor
(after approximately 2
seconds)?
Print a status page.
If any problem is found on the
harness or the connector,
repair or replace it.
Replace the engine/high voltage
PWB. (See page 1-6-26.)
Replace the main motor.
Replace the engine/high voltage
PWB. (See page 1-6-26.)
Print a status page.
End
End
Replace the main motor and the
engine/high voltage PWB at the
same time. (See page 1-6-26.)
