The Encoder Film (A) is fixed to the printer with the springs at the ends. If the film is pushed too strong, it may be dislocated. Do not push the film. Just gently move the cotton swab over the surface of the film.

Caution

Keep your hands off the printer and clean the film with the tip of the cotton swab, as shown in the photo above.

Change the cotton swab to new ones frequently.

Cause and solution

3. Eliminate any stains or smearing from the film until the entire film becomes transparent and clear.

Cause and solution

4. If the trail of detergent is left on the film, clean it using a cotton swab that is moistened with just water.

If moisture is left on the film, eliminate it using a dry cotton swab, and wait until the film dries well.

Cause and solution
