Feeding is not completed within
the specified time after starting
feeding.
When the mirror base is returned for the specified time (6 sec) in mirror initializing
after turning on the power, the mirror home position sensor (MHPS) does not turn
OFF. Or when the mirror base is fed for the specified time (about 6 sec) after start of
copy return, the mirror home position sensor (MHPS) does not turn OFF.
Return is not completed within the
specified time.
When the mirror base is returned for the specified time (6 sec) in mirror initializing
after turning on the power, the mirror home position sensor (MHPS) does not turn
ON.Or when the mirror base is returned for the specified time (about 6 sec) after start
of copy return, the mirror home position sensor (MHPS) does not turn ON.
Main motor lock
When the main motor encoder pulse is not detected for 100msec.
