Dust can accumulate on the media sensors. Blow or gently brush dust away while a soft cloth.
Do not use an air compressor to remove dust. Compressors add moisture, fine grit, and lubricant which can contaminate the printer.
Adhesive particles and airborne substances can cover or coat the optical components in non-typical use media and operating environments.
Clean the Movable Sensor’s window (1). Gently brush away dust or use a can of compressed air; if necessary, use a dry swab to brush away dust. If adhesives or other contaminants remain, use an alcohol moistened swab to break them up.
Use a dry swab to remove any residue that may be left from the first cleaning.
Repeat steps 1 and 2 as required until all residue and streaks are removed from the sensor.
Spray the Upper Web (Gap) Array Sensor (1) below the printhead with a can of compressed air. If necessary, use an alcohol moistened swab to break up adhesive or other non-dust contaminants. Use a dry swab to remove any residue that may be left from the first cleaning.
Swing the printhead actuator arm up until it touches the printer’s top cover. Hold the printhead actuator arm in this position for access to the area below the printhead, see the next graphic.
Spray the upper web (gap) array sensor (1) under the ribbon drive transport.
Spray the ribbon out sensor (2) on the underside of the printhead actuator arm with a can of compressed air. If necessary, use an alcohol moistened swab to break it up. Use a dry swab to remove any residue that may be left from the first cleaning.
