During auto process control execution after the main switch is turned on, the
toner amount in the development unit is normally checked and adjusted using
the ID sensor. However, in some environments, such as where there could be
traces ammonia in the air, copies could appear dirty or too dark because the ID
sensor reading is not reliable.
