20. CLEANING THE UNIT
20-5. Cleaning the Paper
Ejection Outlet Sensor
The paper ejection outlet of this unit has a
sensor for checking the paper ejection state.
This sensor may fail with the error message
“-J2-” when printing powder and paper dust
accumulate on it.
When this message appears, clean the sensor
with an Air Duster (a commercially available air
spray for eliminating dust for office equipment)
as well as a paintbrush, etc.
This sensor consists of two sensors located at
the top and bottom of the paper ejection outlet.
First clean the upper sensor and then the
lower sensor.
Disconnect control cord 1 of folding
plate 1 from the No.1 connector,
release the lock lever, and then remove
folding plate 1.
