Cases of wrong connection
(Refer to the table of
“Connector numbers and
Identifying method of
Harness”)
Symptom caused by wrong connection
Screen display is NOT lit up after main power is turned ON.
Warning of “Ambient temperature Sensor Fault” occurs after main power is
turned ON.
Print positions of nozzle1 and 2 are inverted against the setting of print format.
Shape of ink drop does NOT change even though the value of Auto-phase gain in
“Auto-phase gain adjustment” is changed for the object nozzle.
Printing becomes disordered. APH wave form does NOT change even though the
value of Auto-phase gain is changed.
Charge or deflection-related faults (NO charge, charging too low or too high,
leaking deflection voltage) occurs even though the gutter and charging deflecting
electrode of object nozzle are NOT dirty by ink.
※Note that the wrong connection is NOT allowed by the length of the harness for Connector No.12-No.17
