1–Quick Start

Step 10 — Autocalibrate Scanner

Important: To receive bar code data through the 9-pin configuration port, you must

enable the port with the following command: <K146,,1>.

The MS-880 has a software routine that will automatically search and test a range of

focus, gain and tracking settings and select those that achieve the best reads.

1. With a test label in place, start autocalibration by:

a. ESP, clicking the Autocalibration button on the overhead toolbar

and clicking the Auto Cal button to start autocalibration.

b. serial command, sending <@CAL> from a terminal screen

a. embedded menu, opening the autocalibration menu with <@>

and pressing A.

An “Autocalibration in Progress” message will be displayed on your monitor

along with the pass number and information on the focus, gain, and tracking.

2. Allow some time for the scanner to cycle through the focus, gain, and tracking

settings. Do not move or disturb scanner or label while Autocalibration is in

progress. (It might take 2 to 3 minutes to complete.)

3. When completed, the settings that provided the highest read rate will be selected.

You will see one of the following messages: “Autocalibration Passed”, “Autocalibra-

tion Failed,” or “Original Settings Were Optimal.”

If autocalibration passes, the scanner sends data to your computer and emits a beep

(if beeper is enabled) for each good read and you will continue to see the read rate

percentage and label data in the window below the scanner image.

Note: If you wish to silence the beeper, interrupt reading by removing or blocking the

test label, or send a <K702,0> command to disable the beeper.

If calibration fails, try the following:

• Check the read range for your particular label density.

• Examine label quality and try a different sample label.

• Slightly skew or tilt the label or scanner to minimize specular reflection.

• Ensure that the correct code type is enabled for the label you are scanning.

Note: See Chapter 6, “Autocalibration” for more details on calibration.
