[3-11 ] Conveyor Width Check
1) Lower the lifter table.
2) Verify that the conveyor width can be adjusted from the minimum (50mm) to maximum
(356mm) width in a smooth manner without interference.
[3-12] MFU Clamp Pin and Stopper Position Adjustments
Note: When detaching and moving the MFU, protect the cable.
(For example, keep the cable off the floor so that it does not get run over by the MFU
casters.)
1) Set MFUs at the machine, verifying that all MFUs can be set in a smooth manner.
2) Adjust the stopper bracket so that there is a 0.5mm gap between the urethane MFU stopper
and the MFU's end face.
[3-13 ] MFU IN/OUT Port Check
Mount a feeder (for an I/O check) at the MFU, then use I/O commands to check the operation
of all devices. [Ex] I/O X03C PART FED CMPLT, Y028 SEND PART D1
[3-14] Tape Leaf Sensor Adjustment
1) Set an MFU at the machine.
2) Mount device jigs at D19 and D21.
3) Insert bar jigs (1.8mm dia.) into both slits, then move the sensor until the bar jigs are
positioned in the center of the sensor beam. Partially tighten the sensor at that position.
4) Move the D19 jig to D1, and adjust the sensor receptor side in the same manner, partially
tightening it at this position.
5) Move the jig slits forward one side at a time and use the "IN X00E FDR DETECT" I/O
command to verify that the sensor switches off.
6) After completing this check, tighten the sensors all the way and check again using the same
I/O command.

When the conveyor height exceeds
950mm, shoes are placed over the casters.
In this case, the position of scale mark seal
(indicating the conveyor height) is also
raised by the amount of the shoe height.

[3-15] MFU Set Sensor Adjustment
Adjust the sensor height so that the sensor switches from on to off at a point 0.10mm above the
top face of the MFU guide. Verify that the sensor
definitely switches off at 0.15mm above the MFU guide.
1) Adjust the sensor mounting bracket so that it is flat
(within 0.10mm at both ends).
2) Set a jig so that its detection face is 0.10mm above the
MFU rail's top face, then adjust the sensor height to the
position where the sensor switches from on to off.
3) Set a jig so that its detection face is 0.10mm above the MFU
rail's top face and verify that the sensor is off.
4) Set a jig against the MFU rail's top face and verify that the sensor is on.
5) Set an actual MFU at the machine and verify that the sensor operates normally. Be sure to
confirm this at the I/O screen (X014 MFU, MTU CONECT). At old type main relay boards, the
sensor lamp comes on but the I/O input does not occur. Also be sure that the MFU cable (or
dummy connector) is connected to the QP242 (this is because the "MFU Set" and "cable
connection" confirmations are serial I/O commands.)
* Note: There is an old type MFU (with a black steel bracket on the MFU's mounting face,
extending to the rear), and the current type MFU. The adjustment values are different
for these two types, as shown below.

[3-16] Nozzle Changer Operation Check and Sensor Adjustment (For Single Types Only)
1) Changer UP/DOWN operation check
Use the following commands to raise and lower the changer unit:
[SET]è[POSITION]è[MODULE NO.]è [NOZZLE]è[STATION]è[UP][DOWN].
Verify that the changer operates in a smooth manner.
2) Shutter operation check
1. Open and close the shutter by turning the "X020 NZL SHTTR CLS" and "X021 NZL
SHTTR OPEN" I/O commands on and off. Verify that the shutter opens and closes in a
smooth manner.
2. At the shutter open position, align the center of the shutter hole with the center of the
station nozzle holder hole. This is done by turning the adjusting bolt, and by adjusting
the shutter open/close cylinder stroke.
3. Adjust the shutter OPEN/CLOSE limit sensors. With the shutter open, move the shutter
OPEN sensor downward until it switches off. Next, raise the sensor to the point where it
switches on again, then secure the sensor 0.5mm below that point. Move the shutter
CLOSE sensor upward until it is against the top bracket (it cannot be raised higher than
this), then secure it 0.5mm below that position.
Release the air from the shutter OPEN/CLOSE cylinder and move the shutter by hand,
verifying that the shutter OPEN/CLOSE sensors remain on through a distance of 0.5mm
(at the cylinder stroke). If they do not remain on through a distance of 0.5mm, adjust the
sensor positions (up and down) until the distance is 0.5mm.
4. After completing the adjustments, open and close the shutter again, verifying that the
inputs occur at the I/O IN side. Also verify that the sensor switches off when a nozzle is
clamped (for nozzle clamp detection function).
[3-17] Securing the Head's Vacuum Hose
Secure the head's vacuum hose as shown below with the ejector elbow facing inward (to
prevent hose interference).
