Description

If prints are blurry or distorted, cleaning the encoder film may help resolve the problem.

 

Solution

If vertical lines always appear on printouts or print always shifts from the correct position, or if Error 5100 occurs during printer operation, the Encoder Film inside the printer may be smeared.
Follow the procedures below to check the film condition, and clean it when necessary.

[ Check if the Encoder Film is clear.]

(A) Encoder Film
(B) Rail
CAUTION
  • Do not contact the rail (B). If the rail is contacted, the print quality may be deteriorated.
  • 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.
REFERENCE
  • 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.
3. Eliminate any stains or smearing from the film until the entire film becomes transparent and clear.


 
4. If a trail of liquid 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.
 
5. Close the cover, and plug in the power cord of the printer.
 
6. Press the ON button to turn on the printer.
If an error occurs or a strange sound is heard, service is required.
