Cleaning of pre-heater cover and
after cover
The pre-heater cover and the after cover are easy to be
dirty because of the powder of the media etc.
If it shows dirt, wipe it with a soft cloth soaked in water or
waterish mild detergent and wrung.
Cleaning the Media Sensor
The media sensors are located on the platen in the
backside (3 places) and the bottom surface of the head (1
place). When the sensor is covered with dust, etc., it may
cause false detection of media.
Using a cotton swab, remove the dust, etc. accumulated
on the surface of the sensor.
When cleaning the sensor on the lower surface of the
head is cleaned, move the carriage to the left end by the
operations of step 1 of P.4-12 “Cleaning the Ink Head and
the Area around It”, and clean it.
• Before cleaning the cover, be sure to check that
the pre-heater temperature is low enough.
