How to Use Single-Pass Duplex Scanning with Adobe Acrobat and Kyocera
Question details
The user needs to configure Adobe Acrobat Pro to perform single-pass two-sided (duplex) scanning using a Kyocera multifunction printer.

- Product
- Adobe Acrobat Pro
- Device & OS
- not provided
- Scenario
- Attempting to scan double-sided documents directly into Acrobat using a single-pass document feeder.
- Observed behavior
- Acrobat requires the correct TWAIN/WIA scanner driver and specific software configuration to recognize and utilize the Kyocera single-pass duplex scanning feature.
Ensure your Kyocera printer is powered on, connected to your computer via USB or network, and that the physical document feeder supports single-pass duplex scanning hardware capabilities.
Configure Acrobat Scanning Workflow and Install Drivers
Install the manufacturer's TWAIN drivers and properly select the two-sided scanning option within the Acrobat Create PDF menu.
By default, Windows might install a basic WIA driver for your scanner, which can limit advanced features like single-pass duplex scanning. Installing the official Kyocera TWAIN driver ensures Adobe Acrobat can access the hardware's full capabilities.
Navigate to the official Kyocera support website, download the latest scanner drivers (specifically the TWAIN driver) for your model (e.g., M2640idw), and install them.
Launch Adobe Acrobat Pro, go to the 'Tools' tab at the top, and click on 'Create PDF'.
Click on 'Scanner' from the left menu. In the device dropdown, look for your Kyocera device. If you see multiple options, choose the one labeled with 'TWAIN' rather than 'WIA'.
Click the gear icon or 'Options' button next to the scanner name. In the settings dialogue, locate the 'Sides' or 'Scan Type' option and select 'Both Sides' or 'Duplex'.
Place your documents into the automatic document feeder (ADF) and click 'Scan' in Acrobat. The scanner should now read both sides of the page in a single pass.

Scan and Edit PDFs Easily with WPS Office
If you are experiencing driver compatibility issues with complex scanner configurations, WPS Office offers a seamless and user-friendly PDF scanning tool. You can easily connect your Kyocera scanner to create, edit, and manage high-quality PDFs without the hassle.
- 1. Open WPS PDF: Launch WPS Office and click on 'PDF' to open the dedicated PDF module.
- 2. Access the scanner: Navigate to the 'Tools' tab and select 'Scanner' to initiate the document import workflow.
- 3. Choose your Kyocera device: Select your connected Kyocera scanner from the list of available devices.
- 4. Scan and edit: Adjust your page settings to your preference and click 'Scan'. The document will be instantly converted into a new PDF ready for editing or saving.

Frequently Asked Questions
Why is the 'Both Sides' option grayed out in Acrobat?
This typically happens if Acrobat defaults to a basic WIA driver instead of the manufacturer's TWAIN driver. Selecting the TWAIN driver from your scanner dropdown menu in Acrobat generally restores the duplex option.
What is the difference between single-pass and reversing duplex scanning?
Single-pass duplex scanning uses two built-in sensors to scan the front and back of a page simultaneously as it feeds through the machine. Reversing duplex scanning scans one side, mechanically flips the paper, and then scans the other, which is noticeably slower.
How can I verify if my Kyocera scanner supports single-pass scanning?
You can refer to the printer's user manual or specification sheet (like the M2640idw). Devices with a Dual Scan Document Processor (DSDP) support single-pass scanning, whereas those with a Reversing Automatic Document Feeder (RADF) do not.
Can I test my scanner's duplex feature outside of Adobe Acrobat?
Yes. You can use the native Kyocera Quick Scan utility or the built-in Windows Fax and Scan app. If single-pass duplex works in these programs but not Acrobat, the issue lies within Acrobat's specific driver selection.
