Clean the PCB detection sensors
●Touch the swab tip to detecting section of the PCB detection sensor (transparency type)
and move it as shown below to remove any stain.
●It is recommended that you hold
the swab near its tip when doing
the cleaning.
[Cleaning of the single type]
●With the touch of your hand
or finger, check that the tip
of a swab is in contact with
the detecting section of a
sensor. Then, move the
swab up and down 4 or 5
times to clean it.
[Cleaning of the double type]
●With the touch of your finger
or hand, check that the tip of
a swab is in contact with the
detecting sections of a
sensor. Then, move the
swab up and down 4 or 5
times to clean them (both
sections).
●When moving from one
detecting section to another,
check for the step located
midway between the
sections by touching it with
your hand or finger.
