2 Best Practices
This chapter provides you with recommendations for program
logic, which will allow you to interact efficiently with the i800
Scanner. 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
• Controlling image transfer order – switching between
color/grayscale and bi-tonal
• Jam recovery
• Image file storage locations
• Bar code recognition
• Starting image addresses
• 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
• Patch reading
• Batching
NOTE: The term host in the sections that follow refers to either the
driver or application depending on code logic.
Basic image capture
Basic image capture is the 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.
