(D) Pull out the viscometer IN-side tube (mark G) from viscometer. (The ink in tube will
slightly drip: Fit wiping paper to the end of tube. No reverse flow of ink will occur
inside the viscometer.)
(E) Immediately lift the end of removed tube higher than the level of liquid in main
container, and then continue this for at least 10 seconds (to return the ink in tube
to the main container).
(F) When the ink has drained from tube and air enters it, release the tube. When air
enters the tube, no reverse flow of ink will occur even if the tube hangs down.
(2) Disposing of ink inside viscometer
Remove any ink remaining inside before removing the viscometer.
(A) Turn power on.
(B) Use “Solenoid Valve/Pump Test” screen of “Maintenance Work” to turn on the
pump to MV4, in that order, and operate them for at least 10 seconds. (The ink
remaining in viscometer will return to the main container.)
(C) Turn power off.
(3) Unplugging connectors
Caution: Do not perform this work with power turned on: Doing so will cause
“Viscometer Temperature Sensor Fault” to occur.
Unplug the connectors of lead wires at the back of circulation unit, and pull them
out forward through the grommet hole.
Proximity sensor: 4-pin; Thermistor: 2-pin (blue/black); Coil: 2-pin (blue/black)
(4) Removing viscometer
