2.11.2 Install the EL box

Step 1 Install the connector interfaced with the machine by screwing (tightening torque

30Ncm) using Loctite 241. Also install the feeder board assy by screwing (tightening

torque 20Ncm).

Use a Phillips screwdriver (No.1).

Step 2 Fit the nut plate on the limit switch so that the limit switch’s protruded part is inserted

in the nut plate’s hole. Then fasten the limit switch with a screw using a 1.5 hex

wrench.

Apply Loctite 241 on the screw and tighten it to 30Ncm.

Step 3 Fit the EL box onto the feeder frame by inserting the EL box’s positioning pin into the

feeder frame’s mating hole.

Step 4 Fasten the EL box with three screws using a Phillips screwdriver (No.2).

Tighten the screws to 75Ncm.

Step 5 Connect the limit switch to the feeder board assy at its connector.

Route the limit switch harness over the mount screw of the EL box.

Step 6 Place the cable cover on the EL box. Then install the earth cable of the peel motor on

the feeder body with a screw using a Phillips screwdriver (No.1).

Tightening torque of the mount screw is 40Ncm.

Note

The cable cover must be placed on the correct position to avoid its interference with mount

holes of the feeder side cover and others.

Step 7 Connect the harnesses from the feed motor, ABS board, peel motor, operation switch

and splice sensor (optional) to the feeder board assy at respective connectors.

Each of those gears can be replaced separately; they do not need to be replaced as a set.

2.12.1 Remove the P/O1 roller, P4 and P5 idle gears

Step 1 Remove the top tape box cover referring to “2.2 Replace the top tape box cover”,

step 1.

Step 2 Remove the two screws fastening the “Idle gear 2” cover using a Phillips screwdriver

(No.1) then remove the “Idle gear 2” cover from the feeder body.

Note

It is recommended to insert a precision screwdriver under the cover to remove it, as it is

difficult to remove because of the two positioning pins.

Remove the two screws fastening the P/O tooth 1 block with a hex wrench (Size 2).

Step 3 Insert a scale between the P/O lever assy gear and the feeder body. Then remove the

P/O tooth 1 block and the P/O 1 roller. (Pull them together little by little to remove from

the feeder body.)

Step 4 Remove the three screws fastening the “Idle gear 1” cover with a Phillips screwdriver

(No.1). Then remove the cover from the body.
