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 (
Socket
)
①
Pin2
････････････
Green (
Grounding line
)
⑤

Pin3
････････････
Black (
Switch board)

Pin5
････････････
Yellow (

)
③
Pin6
････････････
Purple (

)
④
Pin8
････････････
Brown (

)
①
If any value exceeds 0 Ω or is ∞, replace the
connection cord.
* For information on the plug 2, refer to “

Checking the grounding line”)
1. Measure the resistance value between Pin 2
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.
