Paper feed encoder film
Handling encoder film
(1) Be careful not to get any grease on the encoder film (carriage encoder
film and paper feed encoder film).
If grease gets on the encoder film, the film's slits will not be read correctly, resulting in
error. If grease gets on the film, use alcohol to wipe it off completely.
(2) Do not fold or scratch the encoder film.
If the film is folded and a white line is created or if a slit is scratched, replace the
encoder film.
