Honeywell 3780 Fusion

Omnidirectional Laser Scanner

Honeywell’s FusionTM 3780 is an affordable hand-held omnidirectional laser scanner with single-line capability that increases retail checkout system efficiency with its automatic in-stand operation, optionally integrated EAS, and industry-leading scan performance.

Fusion combines omnidirectional and single-line laser bar code scanning into a lightweight, ergonomic hand-held form factor. The 20-line scan pattern provides superior scanning over existing single-line hand-held scanners making Fusion ideal for medium-volume retailers including specialty stores, pharmacies, liquor stores, and convenience stores.

An adjustable stand with 50  of tilt and three locking positions provides flexibility for the user to position the scanner for individual comfort and optimal performance. Stabilized with a weighted metal base, the stand may also be hard-mounted to counters or walls.

Fusion also includes CodeGate, a Honeywell patented feature used in the highly successful Voyager series. An integrated infra-red (IR) sensor automatically activates the laser when a bar code is present. The user then properly aligns the bar code before pressing the button, transmitting the data to the host. This feature provides the ability to pass over other bar codes, selecting only the required code. No other scanner offers this much control.

Standard features such as Flash ROM, MetroSelect and MetroSet2 programming, and user replaceable cables protect your investment by enabling Fusion to grow with you and your application requirements.


Primary Omnidirectional Scan Pattern: Aggressive scanning in any orientation, increasing throughput

Secondary Single-Line Scan Pattern: With a push of a button, switch to a targeted single-line for menu scanning applications

Automatic In-Stand Detection: Hands-free operation for presentation scanning reduces operator fatigue

Sleep Mode With IR Wake Up: Multiple sleep modes reduce power consumption, extending life and lowering cost of operation

Optional Integration of RF EAS Antenna: Increases efficiency by simultaneously deactivating RF EAS tags and decoding bar codes
