line
Checking the connection cord for breakage
1. Unplug the connection cord from the station.
2. Disassemble the heating element. {Please
refer to [Replacing the heating element
(heating core)]}
3. Measure the resistance values between the
connector and the lead wires at the socket as
follows:
Pin1･･･････Red {Heating element1 (+)} ①
Pin2･･･････Purple {Trigger (+)} ②
Pin4･･･････Black｛Heating element１(-)｝③
Pin8･･･････Blue {Trigger (-)} ④
Pin9･･･････Yellow {Heating element2 (+)} ⑤
Pin12･･････Brown {Heating element2 (-)} ⑥
Pin13･･････Green (Grounding line) ⑦*
If any value exceeds 0 Ω or is ∞, replace the
connection cord.
* For information on the plug 13, refer to
“■ Checking the grounding line”)
1. Measure the resistance value between Pin
13 and the nozzle.
2. If the value exceeds 2 Ω (at room tempera-
ture), perform the nozzle maintenance. If the
value still does not decrease, check the
connection cord for breakage.
