

Attach a head cap to the tip of head.

Mount it as lightly holding the head as shown in

the gure. The head cap is attached correctly when

its tab clicks.

About the shape of head cap

There are two dierent types of head caps with a dierent shape. Select the one appropriate for a

printing surface.

Flat bottom type

This is suitable for printing on a at surface. As this head cap cannot track a curved

surface or slope well, it is unsuitable for printing on these surfaces. It has high

abrasion resistance against a printing surface and can be used for a long time.

Round bottom type

As this head cap can easily track a curved surface or slope, it is suitable for print-

ing on these surfaces. This head cap, however, tends to be worn out compared

to the at bottom type.

Precautions for use of head cap

Remove dirt and dust from the printing surface.

If you carry out printing without removing dirt and dust attached to the printing surface, it may

deteriorate the printing quality. Make sure to remove dirt and dust from the printing surface before

you perform printing.

For test printing, it is advisable to use materials with no scratches or stains.

Some materials may cause scratches and stains on the head cap during printing, which may aect

the printing quality. Scratches and stains on the materials may also damage the head cap and result

in poor-quality printing. Therefore, for your prior checks on printing, we recommend you perform

test printing with materials without any scratches or stains.
