TWAIN
The driver nearly every scanner ships with. Choose the scanner in job settings, and either show its settings before each scan or leave them as set.
TWAIN and ISIS scanning software, for any document scanner on Windows.
SimpleIndex scans from any TWAIN scanner and from ISIS production scanners, and turns each stack into named, searchable documents filed where they belong, not a folder of image files to sort later. It runs on Windows 11, Windows 10 and Windows Server, and it's licensed once.
01
Two drivers, one job
SimpleIndex talks to the scanner through its driver. Which one you use decides the speed and how the settings are kept, not what happens to the pages afterwards.
ISIS
The faster, more standard driver for high-speed scanners. Its scanner settings are saved in the job file, so every operator scans each document type the same way.
WIA-only scanners
Windows presents a WIA scanner as a TWAIN source, which is fine for a flatbed. WIA drivers don't remember their settings, so turn on Display Settings Before Scan, and many scan only one page at a time. For a document feeder, install the manufacturer's TWAIN or ISIS driver.
Field 02 scanner_to_filed_document
From the scanner to a filed document.
Pick the scanner
Choose TWAIN or ISIS in the Job Settings Wizard, and decide whether operators see the scanner settings before each scan.
Scan the stack
SimpleIndex prompts for more pages when the feeder empties, and can scan two-sided pages on a single-sided scanner.
Work while it scans
Barcode reading and image clean-up can run as pages arrive, so the scanner doesn't wait.
Name and file
Barcodes, OCR or a database lookup supply the index values. Each document is split, named and saved to your folders or system.
03
Scanning options
Set once in the job, so every operator scans the same way.
Processing at scan time
Barcode recognition and image clean-up run while pages are still coming off the scanner, so the batch is half done when the last page lands.
Two-sided pages on a single-sided scanner
Scan the fronts, flip the stack, scan the backs, and SimpleIndex puts the pages back in order.
Lock out colour
Stop operators scanning in colour when the job only needs black and white, so files stay small.
Load more pages
When the feeder empties, SimpleIndex asks for the next stack instead of closing the batch, so one batch can be bigger than the feeder.
Book and magazine scanning
Split two-page spreads into single pages, vertically or horizontally, and put folded magazine pages back into reading order.
Corrupted files set aside
Damaged images, PDFs and Office files are moved to a backup folder before processing, instead of stopping the batch.
04
Keep a production scanner at full speed
A production scanner is only fast while it is not waiting. Keep the scanning job light: barcodes and clean-up during the scan, OCR and exports in a second job. The High Volume Scanning guide shows how to split the work.

Before you connect your scanner.
Does SimpleIndex include scanner drivers?
No. Install the TWAIN or ISIS driver from your scanner's manufacturer, and SimpleIndex lists the scanner in its job settings.
TWAIN or ISIS: which should I use?
TWAIN works with almost every scanner and is right for desktop and departmental scanners. ISIS is worth it on a high-speed production scanner: it runs the scanner at its rated speed and keeps the scanner settings in the job file.
Which edition do I need for ISIS?
Professional includes ISIS. Standard can add it for $200. TWAIN works in both editions.
Does it run on Windows 11?
Yes. SimpleIndex runs on Windows 11 and Windows 10, and on Windows Server 2016, 2019, 2022 and 2025.
Can every operator use the same scanner settings?
With ISIS, yes: the settings are saved in the job file, so everyone scans each document type the same way. With TWAIN, you can hide the scanner settings from operators so the driver keeps the settings it already has.
Can it scan books or magazines?
Yes. Two-page spreads can be split into single pages, and folded magazines are put back into reading order. See book and magazine scanning.
Do I need a 32-bit or 64-bit scanner driver?
SimpleIndex is a 32-bit Windows application, so it uses the scanner's 32-bit TWAIN driver. Most manufacturers install one. If your scanner came with only a 64-bit driver, download the 32-bit TWAIN driver from the manufacturer's site.
What about a network copier or MFP?
If it scans to a shared folder, it needs no driver at all: point the job at that folder. Someone starts the batch, or the Server add-on picks up new files on its own. See network scanners and copiers.
