5.3 MFU cylinder sensors adjustment

1. Note that there are two sensors on each clamping cylinder, making a total of four sensors

on side 1, and four sensors on side 2.

2. The clamp check sensors (X02E side1MfuUpChk) should be adjusted so that they are

ON 0.3mm from the clamp upper limit, and OFF 0.8mm from the clamp upper limit. In

order to adjust them, please follow the procedure below:

3. Place 0.3mm spacers in the four corners of the MFU clamping surface as illustrated

below:

4. Clamp the MFU.

5. Slide the clamp check sensors DOWN until they go OFF then slide them back UP until

they just come ON then tighten the screw (X02E side1MfuUpChk).

6. Unclamp the MFU and replace the 0.3mm spacers with 0.8mm spacers.

7. Clamp the MFU and confirm that the clamp check sensors (X02E side1MfuUpChk) are

OFF.

8. Unclamp the MFU and slide the unclamp check sensors UP until they go OFF and then

slide them back DOWN until they come ON. From the position they first come ON slide

them a further 1mm DOWN and tighten the screw. (X02F side1MfuDownChk).

9. Repeat the procedure for side 2 (X03E side2MfuUpChk) and (X03F side2MfuDownChk).

5.4 Adjusting the waste tape cutter

WARNING: the waste tape cutter plate is an extremely heavy item. Please handle with

care. Also, take extreme caution when handling (or working in the vicinity of) the

cutter blade. It may cause damage or personal injury.

1. Remove the MFU, and the waste tape cutter cover.

2. For the waste tape cutter cylinder air valve speed controller adjustments please refer to

the following table:

Speed controller Air Tube Line Number of turns from fully closed

Cutter close valve U5 7.5

Cutter open valve U6 8

3. Repeat the procedure for the side 2 cutter.

Cutter engagement adjustment

1. Disconnect the air supply to the machine and pull out the two air tubes that supply air to

the tape cutter cylinder. This will allow you to operate the tape cutter manually.

2. Ensure the gap between the movable cutter topside and the fixed cutter underside is

within 0 to 0.03mm when both cutters are engaged.

3. Ensure there are no nicks or cracks in the cutter blade.

4. Repeat the procedure for the side 2 cutter.

Stopper position adjustment

1. Loosen the stopper and position it just at the end of the cylinder stroke.

2. Lock the stopper 1.5 to 2.0mm in from this position.

3. This procedure should be carried out for both the cutter close stopper and the cutter open

stopper.

4. Repeat the procedure for the side 2 cutter.

Retract limit sensor adjustment

1. With the stopper adjustment complete, adjust the side 1 retract limit sensor so that when

the cutter is moved to its retract limit the I/O (Y031 Side1TpCutOrgPos) comes ON

1.5mm in from the cylinder stroke end.

2. Repeat the procedure for the side 2 cutter (Y033 Side2TpCutOrgPos).

5.5 Waste tape duct height adjustment

1. Clamp the MFU and insert feeders in slots number 2 and 49.

2. Set the height of the waste tape duct approximately 1mm higher than the top of the

feeder so that there is sufficient clearance for the waste tape to feed down the duct into

the waste tape box.

3. Set the waste tape duct 1.5 to 3.5mm from the tape feeder end in the Y-direction. Please

refer to the diagram above.

5.6 Measuring the vacuum pressure

1. Equipment: manometer. Nozzle and air tube.

Vacuum pressure check

1. Select [Maintenance A] – [I/O Check] – [Y01F ResetCylinder] – [ON] to raise the parts

vacuum pin and the air blow pin.

2. Select [Maintenance A] – [I/O check] – [Y01F ResetCylinder] – [OFF] to lower the reset

cylinder.

3. Attach the nozzle and air tube at nozzle

position 1.

4. Press the nozzle No.1 vacuum pin down.

5. Select [Maintenance A] – [I/O Check] – [Y016

VacuumPump] – [ON] and check the vacuum

pressure reading on the manometer.

6. The reading should be –600 mmHg (-79.99

kPa) or more negative.
