• Carriage error.
The carriage hits against the left/right stop plate, causing a noise.
The printed characters appear somewhat elongated, or characters or pictures are
displaced.
(1) Check for the presence of grease on the carriage encoder film.
(2) Using lint-free paper moistened with alcohol, wipe the carriage encoder film, being careful not
to damage the film.
(3) If a relatively large amount of grease is found, suspect that some grease may have made its way
to the sensor on the carriage board. Replace the carriage board as necessary (as a carriage unit
itself: HM1-0360).
(4) Replace the carriage encoder film.
