3. Push down on the motor and, when the reading on the tensiometer is at 25,
tighten the socket head cap screws.
4. After the screws are tightened, check the tension again to verify the proper
measurement was maintained.
Synchronizing The Embroidery Heads
Head synchronization is very critical in maintaining proper stitch timing for all four
heads. Without head synchronization, the embroidery quality for those heads that
are not in sync with the rest will become very marginal, if they make stitches at all.
To sync the heads, refer to the following procedure:
1. With the 5 mm hex wrench, rotate the Z drive shaft to the HU position on the
disk at the right end of the Z drive shaft (see Figure 3-5).
2. Turn ON the peripheral and ensure the Z encoder is at the headup position with
the Z drive shaft at HU. (The green LED marked ZINDEX on the front of the right
frame leg of the peripheral [see Figure 3-7] should come ON within +/- 3
degrees of rotation around the HU mechanical position of the Z drive shaft.)
3. Perform the Z Shaft Encoder Calibration procedure in this section of the manual
if the previous step is not met.
4. When the Z drive shaft and Z shaft encoder are set at the HU position, check that
head #1 is set to the mechanical headup position by installing the headup
fixture as described in the Z Shaft Encoder Calibration procedure.
5. Head #1 must be at its mechanical headup position when the Z drive shaft is at
HU and the Z shaft encoder is indicating the headup signal ( ZINDEX LED ON).
To adjust any head other than #4 to the mechanical headup position, you must
remove the shroud over the Z drive shaft section just to the right of the head as
view from the rear.
