MATRIX 410™ REFERENCE MANUAL

FOCUSING MATRIX 410 655-0X0 MODELS (OPTIONAL)

Matrix 410 655-0x0 models are pre-assembled at the factory and have a pre-set focus

distance of 1080 mm. These factory settings allow the 655-0x0 model to be positioned and

calibrated without performing Focusing and Image Density steps.

If necessary, the focus can be changed but not the Diaphragm setting which is fixed at F/11.

To change the Focus Distance for these models, follow the procedure below.

CAUTION

It is strongly recommended to perform this operation with the reader

positioned so that the focus locking screws will not fall out and be lost if

accidently loosened too far.

1. Remove the yellow lens cover in order to access the

Focus Ring.

2. Loosen (but do not remove) the locking screws on the

Focus Ring.

3. Power the reader on. During the reader startup (reset or

restart phase), all the LEDs blink for one second. On the

connector side of the reader near the cable, the “POWER

ON” LED (blue) indicates the reader is correctly powered.

4. Enter the Focus function by pressing and holding the X-

PRESS™ push button until the Focus LED is on.

5. Release the button to enter the Focus function. The Blue

Diamonds™ turn on.

6. Adjust the Focus ring until the Blue Diamonds™ are

perfectly in focus, see Figure 18.

At long focal distances a "skew" angle may cause a noticeable difference in focus

between the two diamonds, in this case select the best possible focus (both diamonds

slightly out of focus). Tighten the Focus Ring Locking Screws.

NOTE

Since correct focusing is influenced by the illuminator lighting, you must

remove your hand from blocking the illuminator to correctly evaluate the

best focus position before tightening the locking screws.

NOTE

Complete configuration can be performed through the VisiSet™ Standard

Setup Wizard including focusing. See Step 8.
