2 Best Practices
This chapter provides you with recommendations for program logic,
which will allow you to interact efficiently with the i1800 Series
Scanners. This high-level information is not intended to be used as a
coding guide. The following information is provided in this chapter:
• Basic image capture
• Switching between color/grayscale and black and white
• Jam recovery
• Image file storage locations
• Bar code recognition
• Controlling print strings
• Electronic Color Dropout (form design, drop-out colors)
• Available image header information and its uses
• Zone processing (recombining images, especially for viewing)
• Programmable keys
• Starting image addresses
• Patch reading
• Batching
NOTE: The term
host
in the sections that follow refers to either the
driver or application.
Basic image capture
Basic image capture is a high-level logic flow for retrieving images from
the scanner.
Follow this sequence to scan documents:
• set up the scanner,
• enable scanning,
• initiate polling,
• feed documents
• and disable scanning.
