Explanation:
This code is used by both the scanner and computer for handshaking. This code indicates that a command, a set of parameters, or a data block was legal and accepted by the receiving device.
The computer should always send an ACK code in response to a data block sent from the scanner, except after the last data block of a page of image data. If the computer fails to send an ACK code within 30 seconds, an interface error occurs in the scanner.
Note:
The ACK code shown here is the ASCII code for 06H. The ACK code does not refer to the ACKNLG signal line of the interface.
