2. Replacement of Linear Measure Sensor
Chapter 5 Head Section
Linear Measure Sensor
(4) Check Modes 1 and 2.
(4.1) Rotate the DD motor and make the checking at the already adjusted position
(marked position).
At this time, confirm that the NS axis (nozzle selection axis) is directed toward
the camera side.
The axis can be rotated by hand for the adjustment with the servomotor being
turned OFF.
(4.2) Change the mode.
(4.3) Press the [MODE] switch (SW3) to change the mode.
Every time the [MODE] switch is pressed, "Mode 1 (ArA1)", "Mode 2
(ArA2)", "Mode 3 (ArA3)", and "Idling (IdLE)" is set.
• When the checked data stays in the specified range (80 to 120%), proceed to
Step (5).
• Mode 1: less than 80, Mode 2: more than 120
The light receiver (square sensor) should be directed downward. (To reduce the
shape of the wave) (Proceed to Step (3).)
• Mode 1: more than 120, Mode 2: less than 80
The light receiver (square sensor) should be directed upward. (To enlarge the
shape of the wave) (Proceed to Step (3).)
* Target Values: "Mode 1" = 80 to 110%, "Mode 2" = 90 to 120%
(4.4) Set the amplifier back in the "Idling" mode.
(5) Follow the steps below to check the accuracy.
(5.1) Move down the NL axis (nozzle level axis) and check the accuracy.
(5.2) Set the amplifier in the "Real-Time Display" mode.
(5.3) Press the [Measurement Mode] switch (SW2).
• Mode Lamp ON (Fig. E10-2)
(5.4) Attach the master nozzle to the No. 1 nozzle holder.
(5.5) Turn on the servomotor and zero the NL axis (nozzle level axis), the NS axis
(nozzle selection axis), and the DD motor (head rotational axis) in this order.
Do not rotate the DD motor when the NL axis is not zeroed. Otherwise, the
motor will break down.
(5.6) Rotate the DD motor by -45 degrees and make a fine adjustment until the
maximum E/NR value of the linear measure sensor is indicated.
(5.7) Rotate the NS axis by the same degrees as the DD motor.
(5.8) Move down the NL axis by +1,000 µm and +2,000 µm and compare it with the
origin position of the NL axis.
• When the value is ±30 µm or less in comparison with the point around 0.5 mm,
proceed to Step (6).
• When the value is ±30 µm or more in comparison with the point around 0.5 mm,
proceed to Step (3).
(5.9) Set the amplifier in the "Max. Value Measurement" mode.
(Only at the adjustment with the device)
• Only the green LED is turned ON.
(6) Attach the cover of the amplifier for the linear measure sensor.

3. Replacement of Doughnut Board
UB22
3.1 Detachment of Doughnut Board
(1) Detach the cover.
Remove the four bolts (M2L6) and detach the transparent cover. (Fig. E12)
(2) Disconnect Connectors CN1 through
CN12 (Change-Over Valves), CN13,
CN21, and CN22 from the doughnut
board. (Fig. E11)
Be careful not to make the
disconnected connectors
trapped by the frame while the
center shaft is rotating.
(3) Detach the four supports (M2) and
then the board from the motor section
as shown in Fig. E12.
(4) Disconnect the board from the connector sections into two halves as shown in Fig. E13
and take out the board.

3. Replacement of Doughnut Board
UB22
3.2 Attachment of Doughnut Board
(1) Put the doughnut boards (in the disconnected condition shown in Fig. E13) on the
DD motor and connect the connectors.
(2) Fix the board at the point where CN12 of the board is located just before the #1
nozzle and the dip switches are located slightly on the left side of the #1 nozzle when
the #1 nozzle is facing the front as shown in Fig. E11.
Apply "1401B" to the four M2 hexagonal supports for the fixation. (Fig. E14)
Confirm that no wires are trapped (pinched) and there is no interference between the
board and the frame when the motor section is rotated by hand.
(3) Connect Connectors CN1 through CN12 (Change-Over Valves), CN13, CN21, and
CN22 to the board as shown in Fig. E11.
Set the #1 and #5 dip switches to "ON".
(4) Attach the cover. (Fig. E14)
Apply "1401B" to the four bolts (M2L6).
