5 Adjustment Procedures

5-1 Laminating Pressure

Note:

To perform the following adjustments, it is necessary to remove both plastic side covers first. See Section 4-1: Disassembly / Reassembly Plastic Side Covers.

There are two ways to adjust the laminating pressure:

1.Adjustment using load cells and display unit.

2.Adjustment using Heat Sensitive Film (JetGuard 5mil or Thermashield 5mil).

This procedure is preferred if the adjustment has to be done in the field, at the site of the end-user.

Both ways need the following necessary tools: 10mm open-ended spanner, small flat-head screwdriver, Allen key 3 mm.

Approximate time: 15 minutes.

5-1-1 Adjustment using Load Cells and Display Unit

To adjust or set the laminating pressure, a Pressure Display Unit is required. These units come in various sizes and/or shapes; however, the load cells typically look like figure 21.

The top roller must be at room temperature!

Proceed as follows:

1.Set the nip setting knob to 10 mm (3/8”).

2.Remove the support brackets for the Image Guide (see figure 22, the RH bracket is shown

here). The two bolts that have to be removed in order to remove the RH bracket, are shown in

figure 23 (in later versions of the machine the way these bolts and nuts are mounted, is reversed).

3.Loosen the adjustment strip on either side of the machine. See figure 23, right-hand strip shown. Note that the strips must not touch the top roller bearing housing during the pressure adjustment procedure.
