Be sure to connect the ground lead to the aluminum die cast on the rear of the cleaner (exit side)
before you clean the cleaner unit. Then clean the unit with, for example, a vacuum cleaner.
(If the cleaner unit is not grounded, static electricity may damage the toner adhesion amount sensor.)
Also wipe the window of the toner adhesion amount sensor with a cotton wool bud or tissue.
(If the window of the toner adhesion amount sensor is dirty, the sensor may no longer function prop-
erly.)
