Waste Toner Vibrator
The waste toner vibrator contains one motor [M]. The motor operates for about one
second at a time. Its vibration prevents the waste toner from clogging the waste
toner path.
The table lists the conditions under which the motor operates.
Machine status Motor operation
During machine start (machine

Suppose: The copier executes two jobs, the first job outputs one paper, and the
second job outputs two papers. In this case, the motor operates one time at the
end of the second job (see

).
Suppose: The copier executes one job, and the job outputs 12 papers. In this case,
the motor operates one time during the fifth printing, one time during the tenth
printing, and one more time at the job end (see

).
Suppose: The copier executes two jobs, the first job outputs one paper, and the
second job outputs 12 papers. In this case, the motor operates one time during the
fifth printing of the second job, one time during the tenth printing of the second job,
and one more time at the end of the second job (see
