INTRODUCTION
Metrologic’s ScanQuest®Engines are miniature laser bar code scanners
designed to be used in OEM applications and decode equipped OEM devices.
The ScanQuest series provides fast, accurate, reliable scanning in a compact,
lightweight package.
Two engine models are available: the IS4125 and the IS4110. The IS4125 has
built-in decoding for versatile OEM operations, while the IS4110 non-decode
engine interfaces directly with decode-equipped OEM devices*. The IS4125 has
flash upgradeable firmware.
* Note: The manufacturer of the end equipment must register with agencies
such as the Food and Drug Administration (FDA). The
specifications required for registration are not obtainable until the
OEM manufacturer uses the ScanQuest Engine in its final
configuration. Therefore, it becomes the responsibility of the
manufacturer who incorporates the scan engine into their product to
comply with all federal laser safety regulations. The manufacturer
must submit a Laser Product Report for the FDA in the US or
similar forms as required by other countries. Metrologic will assist
its customers in complying with the necessary procedures.
Theory of Operation
An infrared (IR) device located behind the scanner window initiates the scanning
process. The IR sensor is active as long as the unit is being powered. When the
laser decodes a bar code, the scan engine transmits the data to the host system.
If the same bar code stays in the field after successfully scanning, the laser stays
on for approximately 4 seconds and then turns off. This prevents unintentional
reads of the same bar code. To read the same symbol more than once, remove
the object from the scan field for approximately 1 second and then present the
symbol again.
If the bar code and object is removed from the field during the scanning process,
the laser turns off. In this stage, the scan engine’s computer remains on
“standby”.
However, if the object stays in the field, the laser remains on for up to 2.5
seconds trying to detect the bar code. To reactivate the scanning sequence,
remove the object.

Figure 2:IS4125
Scanner window: This aperture emits laser light.
Infrared Object Sensor: When a specified time has elapsed without any
scanning, the unit will enter a “standby” mode. To
reactivate the unit, present an object in front of the
IR (infrared) sensor.
Ribbon Cables: This IS4110 has a 10 position FFC/FPC cable and the
IS4125 has a 12-position FFC/FPC cable. Refer to
Scanner Termination starting on page 15.

Label Locations
The serial number label is located on the bottom of the unit. On the top of the
unit is the “avoid exposure” and model number label.
The following are examples of these labels:

Maintenance
Smudges and dirt can interfere with the proper scanning of a bar code.
Therefore, the output window will need occasional cleaning.
1. Spray glass cleaner onto lint free, non-abrasive cleaning cloth.
2. Gently wipe the scanning window.

IR SENSOR ACTIVATION
An infrared (IR) sensor located behind the scanner window initiates the scanning
process. In short range mode the signal projects approximately 101.61 mm –
177.84 mm (4" – 7") beyond the output window. In long range mode the signal
projects approximately 228.61 mm – 330.21 mm (9" – 13") beyond the output
window. The IR sensor remains active as long as the unit is powered.
When the unit remains dormant for a time, the laser will turn off. In this stage, the
scan engine’s computer is on “standby”. To reactivate the unit, present an object
within the scan field.
