Fitting the

Squeegees

It is usual to fit two trailing edge squeegees and use the machine in the Print/

Print mode.

When fitting a single squeegee (trailing edge or diamond section) to the

machine, it must be fitted to the front squeegee mount only.

The following procedure describes a double trailing edge squeegee

configuration fit to the machine printhead mounting assembly.

1. From the Ready page, select Product Changeover.

2. Select Change Squeegees.

3. The print carriage is driven to the front position.

4. Open the front printhead cover.

5. Fit the rear squeegee to the rear squeegee mount tightening the thumb-

screws finger tight.

NOTE

The locking thumbscrews on the rear squeegee are positioned wider apart

than those fitted to the front squeegee and the keyway slot is positioned on the

left hand side of the rear squeegee.

Mounts to Lateral

Squeegee Mounts

NOTE

The lateral squeegee - squeegee mechanism, is identical to a standard

squeegee mechanism. Refer to the sections: Fitting The Squeegee Printhead

Mechanism and Squeegee Drive Belt Replacement procedures.

To change from a printer with standard squeegee mounts fitted to having

lateral squeegee mounts fitted proceed as follows:

1. Power up the printer to allow it to initialise. The squeegees move to their

home positions.

2. Power down the printer.

3. Open the printhead front cover.

4. If fitted, remove and stow the standard squeegee blades safely away.

5. At the bottom of the squeegee mounts locate the three M4 cap headed

screws.

6. Using a 3mm Allen key, remove both squeegee mounts and stow them,

with their screws, safely away.

M4 x 14mm cap headed screws provided. Do not fully tighten as adjust-

ment is needed.

NOTE

The lateral squeegee mounts should have been stored away with three M4 x

14mm cap headed screws. Do not attempt to fit the mounts using the cap

headed screws removed from the standard squeegee mounts.
