For the 3118, the ISLDE call at C feeds the document from the feed tray into the scanner. If there is a document already present inside the scanner, it is ejected, and the document in the feed tray is fed in. The call has only one parameter, the identifier of the scanner device image. A scanner device image must have been created before this call can be used.

The 3118 aligns the top edge of the paper with the top of the (empty) created scanner device image, and centers the paper laterally.

For the 3117, the ISLDE call resets the scanner so that it is ready to scan from the top of the paper.

The paper size does not have to match that implied by the IMACRT parameters. For example, the program creates a scanner device image that is 6 inches horizontally by 4 inches vertically. If a document that is 8 inches horizontally by 5 inches vertically is fed top-first into the scanner, the program captures the middle 6 inches of the document horizontally, and the top 4 inches vertically.
