Sensor Cleaning
Dust can accumulate on the media sensors. Use a can of compressed air. Do not use an air compressor to
remove dust. Compressors add moisture, fine grit, and lubricant which can contaminate your printer.
1. Clean the Movable Sensor’s window. 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 it up.
2. Use a dry swab to remove any residue that may be left from the first cleaning.
3. Repeat steps 1 and 2 as required until all residue and streaks are removed from the sensor.
