Patch code sheets — document capture template

Patch codes are separator sheets that scanners have read for decades: a pattern of four thick and thin bars. DocView reads patch codes 1, 2, 3, 4, 6 and T in any orientation; here patch T starts a new document and the sheet is removed.

Try it

Create a Batch Setup from this template (Batch Setups › New Batch Setup, tab System features), and download its sample documents from the template's card (Download samples). Then: Print patch-T.pdf, or import batch-with-patch-sheets.pdf. The batch has three documents and the patch sheets are gone.
