What a page count assumes. Splitting every N pages is the simplest rule there is, and it is the right one when every document has the same length, such as a stack of one-page receipts or two-page forms. ScanRoute offers it. Legal paper is rarely that uniform. One extra page anywhere in the stack, an enclosure or a fax cover, shifts every break after it, and every document from that point on is cut in the wrong place. Nothing in a page count can tell that the middle of the stack slipped.
What a separator marks. A separator says this is where a document starts, wherever it falls. ScanRoute splits at a page that carries a Code 128 or QR barcode starting with your separator prefix, at a blank page, or at either one in the Barcode or blank page mode. The document in between can be one page or forty. The separator page is dropped from the output unless you choose to keep it, and back-to-back separators count as a single break.
Barcode sheets or blank pages. Blank pages need no printing, which makes them the quick choice for a day of mail. Their weakness is the copier that scans both sides: the blank back of a one-sided letter looks like a separator too. Scan one-sided, or use barcode sheets, because a page only counts as a barcode separator when its barcode starts with your prefix. Set a prefix such as SR- so a barcode printed on a court form or a courier label inside a document is not taken for a break. The free printable separator sheets on the product page carry SR- values; print them at actual size and test a short stack first.
Getting the matter number into the name. The name comes from one zone read on the first content page of each document. Outside senders put their references in different places, so a zone over a letterhead will rarely find the same thing twice. Two approaches work. Place a received stamp or a printed label in the same corner of every first page, with a line such as RECEIVED 2026-09-22 M-24-0193, and draw the zone there. Or let reads that fail their checks wait in the inbox, where the assistant types the matter number while looking at the zone crop. Either way, a template such as {Matter}\{Date}_{Type}.pdf creates the matter folder and a dated name.
What ScanRoute will not do. It cannot start a new document wherever a word such as Re appears in the text. It reads one zone per document, not the whole letter. It works with PDF files in folders on this PC, not on shared drives, and it is not a document-management server. It also makes no claim about how your office must keep its records. It splits and names, shows every result in Preview, writes nothing until you commit, and leaves the original scan untouched.
