Item Purpose Overview Ref.
• HEAD2: Head heater 2
CHECK INK IC • To check for Ink IC chip
contact defects, etc.
• Error: [IC=1 ERR=1] is displayed. -
CARTRIDGE
VALVE
• To check the cartridge valve
operation
• Press the [FUNCTION] key to toggle
between OPEN and CLOSE.
-
Maint.Cartridge • To check the operation of the
maintenance liquid cartridge
slot
• Cartridge detection sensor and ink-end
sensor check
• Valve operation check
• Drip prevention shutter and shutter
sensor operation check
-
AGING • To test durability
• When communication
problems are suspected
between PCBs
• This is used to check the continuous
operation of the motors and units.
• PCB communication test: This is used
to check communication between the
main PCB and the other PCBs.
P. 155
Check Encoder • If the "2.1.4 150LPI Encoder
PCB"(P. 39) was replaced
• If "3.1.6 Encoder Sensor
Height Adjustment"(P. 119)
was performed.
• Periodic check item
• This is used to check the difference
between the Y drive motor encoder
value and the linear encoder scale
coordinate value, and check the
position of the encoder PCB.

Paper Sensor • If an abnormality is detected
in media width detection
• @@@: Sensor value read at SLOP-
ON
• $$$: Sensor value read at SLOP-OFF
• ***: Difference between @@@ and $$
$
• Sensor readings are refreshed
periodically (every 150 ms).
-
Action Test • To check the operation of
moving parts.
