6-5 : Cleaning of the paper feed, double feed detection, paper ejection photo sensors
[ Cleaning the paper ejection photo sensor ]
Diagram showing that the folder roller is
removed (Refer to the figure on page 46.)
If only one sheet of paper is being fed, remove
the paper dust on the part of the paper ejection
photo sensor indicated by the arrow, using a soft
cotton swab.
[ Cleaning the paper feed and double feed detection photo sensors ] ]
Open the safety cover, and using an air duster,
clean [1] the surface of the paper feed photo
sensor (black resin face), and [2] the surface of
the double feed detection sensor.
(Instead of an air duster, a damp, but not
dripping, cotton swab or similar implement may
be used.)
Caution
！
If using a cotton swab to clean the sensors, ensure that no cotton lint is left behind.
Insufficient cleaning may cause the paper feed to stop, or an error to occur after only
the first sheet of paper is fed.
Only turn the machine on when the sensor has fully dried after cleaning.
