Using the Imager
The CN4 has two available area imagers: EA11 and EA21. The EA11
provides a “laser-like” aimer and is optimized for a scan-intensive
environment. The EA21 provides a laser framer and is optimized for
document imaging. Both area imagers can scan 1D and 2D bar codes.
The following table shows the minimum bar code size supported by
each imager.
The area imager in the CN4 can perform multiple tasks:
• Reading bar codes, including 1D, 2D, and composite symbologies
and postal codes. For more information, see the next section,
“Reading Bar Codes.”
• Capturing images. Use the imager like a digital camera to take
high-quality, grayscalegrayscale pictures. For more information,
see
“Capturing Images” on page 29.
• Capturing signatures. Use the imager to “photograph” signatures
on business forms, or to capture onscreen signatures or line
drawings. For more information, see
“Capturing Signatures” on
page 32.
• EA21 only: Document imaging of full business forms such as bills
of lading or invoices. For more information, see
“Capturing
Documents (EA21 only)” on page 32.
